Hi all.

I have implemented a web-app which contains an async servlet using Servlet 3.0 API and JBOSS6.1.0.Final version.

Via longpolling/server-push, the client (jsp) is informed about changes on the server.

Sometimes, the exception "java.lang.IllegalStateException: invalid async context for Servlet " occurs.

What is generally the cause of such an exception ?

How can I avoid this AsyncContext's invalid state ?

I'll very appreciate any feedback.

Thanks in advance.
