<sessionId/> is not necessary, but if you don't specify either a <sessionId/> or (better yet) <nosession/> then you're going to start accumulating 1 session in the server per request, which is bad.
If you want to see sample valid SOAP for your server version, turn on the debug window for the AJAX client and use the app. All the SOAP sent between client and server should appear in that window. (Search the forums for instructions on how to turn on the debug window.) |
