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.

Environment: GWT 2, Spring + Spring Security 3, gwtrpc-spring 1.01
I am trying to implement authentication for my GWT application using
Spring Security. But when I call the RPC.invokeAndEncodeResponse
method it throws an SerializationException. Looking at the stack trace
I see that AccessDeniedException from Spring is thrown, but for some
reason GWT can't serialize it.
try {
RPC.invokeAndEncodeResponse(target, serviceMethod, args,
serializationPolicy)
} catch (SerializationException e) {
logger.error(e);
}
AccessDeniedException inherit from java.lang.RuntimeException. It has
a no-arg constructor inherited from RuntimeException. It does
implement Serializable.
What am I missing here???
