Sets the stream from which the component will read the HTML version of the message.
public void setMessageHTMLStream(java.io.InputStream messageStream);
This method sets the stream from which the component will read the HTML version of the message. Once set, the component reads the contents of the stream, and populates the MessageHTML property with the HTML version of the message. The corresponding plain text version is provided into the MessageText property.
When this property is called, the component automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.
