I have got such error, when tested gwt-application with Tomcat server. I
saw server log and found this:
SEVERE: Exception while dispatching incoming RPC call
java.security.AccessControlException: access denied
("java.lang.reflect.ReflectPermission" "suppressAccessChecks")
at
java.security.AccessControlContext.checkPermission(AccessControlContext.java:366)
at java.security.AccessController.checkPermission(AccessController.java:555)
at java.lang.SecurityManager.checkPermission(SecurityManager.java:549)
at
java.lang.reflect.AccessibleObject.setAccessible(AccessibleObject.java:128)
at
com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter.serializeClass(ServerSerializationStreamWriter.java:751)
.........
My application have not reflection permissions.
I have add this string to the catalina.policy file:
permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
After this everything worked.
