The problem is:
Caused by: com.google.gwt.user.client.rpc.SerializationException: Type
'[Ljava.lang.String;' was not included in the set of types which can
be serialized by this SerializationPolicy or its Class object could
not be loaded. For security purposes, this type will not be
serialized.
which probably indicates there is nothing in any of your RPC service
interface declarations that mentions String specifically, so it is not
included in the RPC "white list". Are you declaring the ArrayList like
this:
ArrayList<String> myService(...) {
....
ArrrayList<String> myList = new ArrayList<String>();
.....
return myList;
}
If not then this will probably make the problem go away.
