Re: GWT app doesn't work behind reverse proxy

Thanks for the reply and information, it sounds like there is a workaround then for the GWT part but we still have the same/similar issue with Tomcat's authentication.  We need to solve that too else its only a partial solution.

I am not familiar with tomcat and your overall setup but it sounds like your session cookie might not be correct during authentication and you reach some login timeout. Maybe Tomcat sets a JSESSIONID cookie for localhost when accessed through the proxy. Thats why I said you might need to rewrite cookies in your proxy.

 

Btw, regarding the GWT serialization issue...I read online some say a way around this is to use IsSerializable instead of Serializable to mark objects going across the wire but its not clear if that 'trick' still works or not.  Also some say to drop GWT RPC and use JSON instead that doesn't have the same issue.  I don't really care what the format of the data is going across the wire, I just need the results to work.  Is there an easy way to switch the RPC format to JSON or some other format that doesn't have this issue?

When you use IsSerializable then GWT will fallback to an old serialization policy which does not require a RPC policy file. I am not very familiar with that old serialization policy but it is considered legacy.

You can not change the way GWT-RPC works but you could stop using GWT-RPC and switch to REST / JSON using https://resty-gwt.github.io . As its API on client side is pretty similar to GWT-RPC it should be easy to migrate. On server side you would use some JAX-RS 2.0 implementation like Jersey or RESTEasy (or others).
