GWT does not serialize RuntimeExceptions. If it did, it would have to generate javascript equivalent of several useless Exception classes.
If you want the exception to propagate to the client, you have to do the following - a) The Exception should be Serializable b) It should be in the client package (meaning, GWT Compiler has the source code) c) The Exception should be declared in the throws clause of your RPC interface In your case, AccessDeniedException is only meeting criteria (a). You would have to create a new Exception class that clones AccessDeniedException and then push it down the network. --Sri http://blog.530geeks.com On 12 March 2010 19:02, d95sld95 <[email protected]> wrote: > Environment: GWT 2, Spring + Spring Security 3, gwtrpc-spring 1.01 > > I am trying to implement authentication for my GWT application using > Spring Security.
