Server side equivalent of RpcRequestBuilder

[Carlos Silva]

Hi,

I'm using an RpcRequestBuilder to add a session id header to the http request being made to the server.

Now, what I wanted was to on the *server* side, get the request and before it get's executed (call the method), check if the session is valid.

How can I accomplish this?

My biggest problem is understanding the full workflow (classes involved) of a GWT-RPC request, so I really don't know which class to create/extend/define.

Any help is good help :)

Thanks in advance.

Use a Servlet Filter. It sits in front of servlets and you can do stuff before a servlet executes and after it has done its work.
