Hi, I added below additional operations also to the Gmail connector.
- "send mail message" - "delete mail message" - "read mail message" - "set labels to a mail thread" So now, altogether 12 operations are implemented including two authentication operations. Below given the way how I handled attachments in sending and reading Gmail messages. *Reading e-mail messages* The attachments found in each message are added to the operation context where, the content ID is created by concatenating both "e-mail message ID" and "attached file name". Then, the comma separated content IDs of the attachments are returned to the user in the response as given below; <ns:attachemnts>1464782427362087215gmail-connector-1.0.0.zip,1464782427362087215mail.odt</ns:attachemnts> *Sending e-mail messages* User can add files to the operation context where each file's content ID should be equal to its file name. Then, he can specify again the file names which, should be attached to the e-mail message, using the parameter named "attachmentIDs". Then, the connector will read the attachments from the operation context using the content IDs(file names) specified by the user and attach them to the mail body with the same file names. Please let me know if you have any concerns regarding this implementation.
