Dropbox Adapter

Properties   Config Settings  

The Dropbox Component allows easy uploading and downloading to and from the Dropbox service.

Remarks

The Dropbox Adapter provides a simple way to upload and download files from the Dropbox service.

To begin, the adapter must first be configured to allow access to the Dropbox using OAuth.

Open the OAuth Authorization dialog by clicking the ellipses (...) button of the OAuthAuthorization property at design time. This will open a dialog. Within the dialog specify the ClientId, ClientSecret, and CallbackURL values for the registered application.

After specifying the necessary values press the Authorize button to authorize the application. This will launch a browser and prompt the user to grant access. After access is granted the adapter will populate the following values:

• AuthorizationString
• RefreshToken
• ExpiresIn
• TimeStamp

All necessary values will be saved in the CacheLocation for use in subsequent requests by the adapter. The adapter will use the cached values and will automatically refresh the token if needed. In this way any user interaction is only required at design time, not at runtime.

Dropbox Receive Adapter

At runtime the adapter will connect to the Dropbox service every PollingInterval and list the directory specified by RemotePath. All files that match the FileMask will be downloaded and submitted to the BizTalk Message Engine as individual messages.

In order to guarantee that files are not downloaded multiple times, you may set the DeleteMode to remove files from the server that have been downloaded. Alternatively DownloadCacheFile may be used to keep a list of files which have already been downloaded.

Dropbox Send Adapter

The adapter will connect to the Dropbox service whenever it has a message to send. The adapter will attempt to upload to the specified RemotePath. If Overwrite is set to True, the adapter will delete or overwrite remote files as necessary to complete the operation.

Please refer to the section on adapter configuration for a description of how to configure receive locations and send ports for this adapter.

Setting the Dropbox Adapter Configuration Properties for a Dynamic Send Port

A dynamic send port does not provide any transport configuration options in BizTalk Explorer because it is expected that these properties will be provided with the context properties associated with the message. These properties can be set in a custom pipeline or in an orchestration. To set message configuration properties in an orchestration you can do the following:

• Add a Construct Message shape to your orchestration.
• Configure the Construct Message shape to construct a new message. (for example Message_2)
• Add a Message Assignment shape to the Construct Message shape.
• Add code to the Message Assignment shape to initialize the message that you constructed and to set the appropriate configuration properties for the message.

MaxBatchSize Property (Dropbox Adapter)

The maximum size, in MB, of the current batch (0 indicates no limit).

Data Type

Integer

Default Value

0

Remarks

This property limits the maximum amount of data the adapter can store before finalizing and processing the current batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileCount Property (Dropbox Adapter)

The maximum number of files in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

10

Remarks

This property places a limit on the number of files that can be transmitted in a single batch.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileSize Property (Dropbox Adapter)

The maximum size, in MB, of a file in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

0

Remarks

This property limits the maximum size of any file in the current transmission batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxPersistentConnections Property (Dropbox Adapter)

The maximum number of simultaneous persistent connections when sending.

Data Type

Integer

Default Value

1

Remarks

This setting specifies the maximum number of simultaneous persistent connections when sending.

The default value is 1, which limits the adapter to using one persistent connection for the adapter at any one time. This means when ConnectionLifetime is set to Persisted the send adapter will first check to see if an existing connection is present before transmitting data. In the case where a connection exists but another instance of the send port is using the connection the adapter will wait for the connection to become free. A value of 1 effectively serializes all communication for the send port through one persistent connection.

By setting a value greater than 1 a pool of persistent connections can be created. This allows multiple simultaneous persistent connections to be used. When the send adapter is active it will check to see if there are any existing connections. In the case where a connection exists but is being used by another instance of the send port it will attempt to create a new persistent connection. If creating a new persistent connection would exceed the limit specified in this setting the adapter will instead wait for a connection to become free. Setting this to a value greater than 1 allows multiple simultaneous connections to be made while still taking advantage of persistent connections to reduce the overhead of re-connecting.

Note: This only applies to the send adapter.

The default value is 1.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

MaxThreads Property (Dropbox Adapter)

The maximum number of threads that the component may consume.

Data Type

Integer

Default Value

20

Remarks

This property limits the number of concurrent threads that the adapter may consume while completing its work.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

MaxTransmissionBatchSize Property (Dropbox Adapter)

The maximum number of messages that can be sent in a single batch.

Data Type

Integer

Default Value

1

Remarks

This property controls the maximum size of an outbound message batch.

Note: be careful when modifying this property as it directly effects the efficiency of the transmit adapter. Setting MaxTransmissionBatchSize to a low value in an environment that requires transmission of large quantities of data will result in the adapter accumulating several small batches. If TransmitBatchMode is set to Parallel, this will result in the adapter transmitting many small batches at once and can put a heavy load on the processor.

Conversely, if TransmitBatchMode is set to Serial, setting MaxTransmissionBatchSize to a large value may result in long transmission delays as the adapter will wait on existing work to complete before accepting new messages from the BizTalk Message Engine. This is especially true when the adapter is transmitting large data.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

OAuthAuthorization Property (Dropbox Adapter)

• ClientSecret
• ExpiresIn
• RefreshToken
• ServerAuthURL
• ServerTokenURL
• ServiceProvider
• TimeStamp

Other Property (Dropbox Adapter)

Defines a set of configuration settings to be used by the component.

Data Type

String

Default Value

""

Remarks

The adapter accepts one or more configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the adapter, access to these internal properties is provided through the Other property.

The Other property may be set to one or more configuration settings (name/value pairs). Set one setting per line. For example: configname1=value1 configname2=value2

Overwrite Property (Dropbox Adapter)

Whether or not the component should overwrite files during transfer.

Data Type

Boolean

Default Value

true

Remarks

This property is a value indicating whether or not the adapter should overwrite files on the server if they already exist. If Overwrite is false, an error will be thrown whenever RemoteFile exists before an upload operation.

This property is not available in the Receiver.

PollingInterval Property (Dropbox Adapter)

The amount of time, in seconds, between download attempts.

Data Type

Integer

Default Value

60

Remarks

The adapter will wait for the number of seconds indicated before attempting another download.

This property is not available in the Sender.

ReceivedFileDate Property (Dropbox Adapter)

The modified date of the remote file received by the component.

Data Type

String

Default Value

""

Remarks

This value contains the modified date of the remote file received by the adapter. It can be read from the context of a message received by a adapter receive location.

By default the datetime format used is "yyyy-MM-dd'T'HH:mm:ss". To modify this format set DateFormat.

This property is not available in the Sender.

ReceivedFileName Property (Dropbox Adapter)

The name of the remote file received by the component.

Data Type

String

Default Value

""

Remarks

This is the file name returned by the server.

This value is also placed in the File.ReceivedFileName and the [Adapter].ReceivedFileName context properties. This is to ensure compatibility with other adapters that poll those context properties when filling out macros such as %SourceFileName%.

This property is not available in the Sender.

ReceivedFileSize Property (Dropbox Adapter)

The size of the file in bytes.

Data Type

Integer

Default Value

0

Remarks

This property holds the size of the received file in bytes. It can be read from the context of a message being received by a adapter receive location.

This property is not available in the Sender.

RemoteFile Property (Dropbox Adapter)

The name of the remote file.

Data Type

String

Default Value

"%SourceFileName%"

Remarks

This property specifies the remote filename. This is either an absolute path, or a relative path based on RemotePath. For instance:

Filename only: file.txt

Relative Path: subfolder/file.txt

Absolute Path: /MyFolder/subfolder/file.txt

This property is not available in the Receiver.

RemotePath Property (Dropbox Adapter)

The current path on the server.

Data Type

String

Default Value

""

Remarks

This property specifies the path on the remote server. This may be set to an absolute or relative path.

If the path begins with a "/" it is considered an absolute path.

If the first two characters of the path are ".." this indicates a change to the parent directory.

RequeueEndpoints Property (Dropbox Adapter)

Whether to requeue receive endpoints if the polling interval has not been reached.

Data Type

Boolean

Default Value

false

Remarks

This setting controls whether receive endpoints are requeued for later processing if the polling interval has not yet been reached. When this setting is set to No (default) each thread will block until the polling interval for the corresponding receive location is reached. If there exist more active receive locations than MaxThreads it is possible for some threads to block the execution of others since they may be waiting for a polling interval.

When this setting is set to Yes if the polling interval has not been reached the thread will not block until the polling interval is reached, and instead the endpoint will be requeued to be processed later. This lets subsequent endpoints in the queue to be processed.

If MaxThreads is set to a low value and there are a larger number of receive locations setting this to Yes will help assure that polling intervals are respected and receive locations poll in a timely manner.

The default value is No.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

RuntimeLicense Property (Dropbox Adapter)

Specifies the component runtime license key.

Data Type

String

Default Value

""

Remarks

You can use the RuntimeLicense property to set the runtime key for the adapter license.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

SSLAcceptServerCert Property (Dropbox Adapter)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

Data Type

Certificate

Remarks

If it finds any issues with the certificate presented by the server, the adapter will normally terminate the connection with an error. You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

This property is used to set a Public Key Certificate.

Ordinarily, the system will attempt to locate the public key in trusted certificate stores in the system registry. If a match is found, the certificate is trusted, and the process proceeds without error. If the certificate is not trusted, the adapter will report an error.

You may explicitly set a public key, either to accept a key that is not installed on the system, or to ensure that a specific key is presented. Public key certificates may be loaded from the machine registry or from file. If you click on the ellipses, a certificate selection dialog will open. To select a public key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of available certificates will be shown below.

Alternatively, you may specify a public key on file. Select the PEM or Certificate File tabs to load a public key from file. You can use the browse button to examine the file system for the certificate that you wish to use. Public keys typically are stored in .CER, .DER, or .PEM files, but other formats may be used. You can click on the Open button to examine the contents of the certificate. Or, if you have a certificate stored in memory, you can write the contents of the certificate into the text box provided. Note that if you are loading a certificate from memory, the certificate must be Base-64 encoded, or the string representation of the certificate may become corrupted and uninterpretable.

Regardless of how you selected the certificate, once you hit the OK button, the adapter will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the adapter was not able to verify the selection, a dialog box will appear instead detailing the verification error.

Note: You may also set the Accept Any field to Yes without opening the certificate selection dialog to force the adapter to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes. Set the LogMode to Info to cause the adapter to report the server's credentials to Location.

SSLCert Property (Dropbox Adapter)

The certificate to use for client authentication during the SSL handshake.

Data Type

Certificate

Remarks

This property is used to assign a specific certificate for SSL client authentication.

This field is used to set a Private Key Certificate.

Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format. If you click on the ellipses, a certificate selection dialog will open. To select a private key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of certificates which have private keys will be shown below.

To select a private key certificate from a file in PKCS#12 format, select the PFX Store tab. The browse button can be used to examine the file system for PKCS#12 (.pfx or .p12) certificates. If you wish to examine the certificate, provide the password in the field provided and click on the Open button to examine the file store for certificates present. To load a certificate from PEM files, select the PEM tab. Like the PFX file selection, you can specify the password and click the Open button to examine the certificates in the PEM store, or you may paste any PEM data stored in memory.

Regardless of how you selected the certificate, once you hit the OK button, the adapter will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the adapter was not able to verify the selection, a dialog box will appear instead detailing the verification error.

TempPath Property (Dropbox Adapter)

A temporary local directory where data can be stored before the component processes it.

Data Type

String

Default Value

""

Remarks

This property indicates a temporary directory where the adapter can store any data before the adapter processes it. If TempPath is empty, the adapter will receive all data to memory. If set, the adapter will generate and write all inbound data to a temporary file in the specified directory.

Once the file is submitted, the adapter will handle closing the file stream and deleting the temporary file. However, if the adapter is shut down during a transfer some temporary files may be left in the directory. To ensure optimal performance, server administrators should check the directory regularly and remove old or extraneous files.

This property accepts the "%TEMP%" macro, which will be replaced with the default system temporary directory at runtime. Note: by default, this property is empty and the adapter will use memory streams to store all inbound data before submitting it. It is recommended that you use a temporary directory when downloading large batches or batches containing large files to alleviate potential increased memory requirements.

This property is not available in the Sender.

Timeout Property (Dropbox Adapter)

A timeout for the component.

Data Type

Integer

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion, or an error condition is encountered.

If Timeout is set to a positive value, the adapter will wait for the operation to complete before returning control.

If Timeout expires, and the operation is not yet complete, the adapter fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when data is successfully sent or received.

Optionally, the behavior of the adapter may be changed to absolute timeouts, i.e. the adapter will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the AbsoluteTimeout configuration setting.

The default value for the Timeout property is 60 (seconds).

TransmitBatchMode Property (Dropbox Adapter)

How the transmitter processes batches.

Data Type

Enumeration

Possible Values

Parallel (0)
Serial (1)

Default Value

0

Remarks

This property controls how the transmitter processes message batches:

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

TransportLog Property (Dropbox Adapter)

Tells the component where and how to report information about its operations.

Data Type

Log

Remarks

This is a Log type property which contains fields describing how and where the adapter will record information about its execution.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

URI Property (Dropbox Adapter)

The Uniform Resource Identifier (URI) of the send port or receive location.

Data Type

String

Default Value

""

Remarks

This property specifies a URI for the send port or receive location. Setting this property is optional.

By default the adapter will automatically generate a URI. You may choose to specify your own value here to be used in place of the generated URI.

If this value is specified it must begin with the correct prefix, as seen in the default value.

Certificate Type

The digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Certificate();

Creates a Certificate instance whose properties can be set.

public Certificate(string certificateFile);

Opens CertificateFile and reads out the contents as an X509 public key.

public Certificate(byte[] certificateData);

Parses CertificateData as an X509 public key.

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, string subject);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the constructor will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, byte[] encoded);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the constructor will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, string subject);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or base64-encoded) containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the constructor will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, byte[] encoded);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or base64-encoded) containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the constructor will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

Firewall Type

The firewall the component will connect through.

Remarks

When connecting through a firewall, this type is used to specify different properties of the firewall such as the firewall Host and the FirewallType.

Fields

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Firewall();

Log Type

A log where the component will record information about its operations.

Remarks

This describes how and where the adapter will record information describing its execution.

Fields

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Log();

public Log(LogTypes logType, string location, LogModes logMode);

OAuthAuthorizationParam Type

This type holds details of the OAuth authorization.

Remarks

This type holds details of the OAuth authorization.

Fields

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public OAuthAuthorizationParam();

Proxy Type

The proxy the component will connect to.

Remarks

When connecting through a proxy, this type is used to specify different properties of the proxy such as the Server and the AuthScheme.

Fields

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Proxy();

public Proxy(string server, int port);

public Proxy(string server, int port, string user, string password);

Config Settings (Dropbox Adapter)

The adapter accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the adapter, access to these internal properties is provided through the Other property.

Dropbox Config Settings

SSL Config Settings

General Config Settings

Supported Macros

The adapter also supports the following Macros. These values are not case sensitive and would be supplied to a property in the form %MacroName%.
