GWT app engine openID error 500

We are developing a webside with gwt. And we are implementing openID (openid4java), but we are stuck when we are running it with app engine online. Locally it works perfect, but when we deploy on app engine we get error message 500 and this error message :

javax.servlet.ServletContext log: Exception while dispatching incoming RPC call

Openid4java does not work with GAE since GAE excludes certain redirects. Refer link.

You can do it using Federated Authentication via OpenID in Google App Engine

It seems you are using threads. Google app engine does not support Threads.

Yes it will work locally,But when you deployed it throws that exception at run time
