Dynamic proxies can be used for many different purposes, e.g. addAnnotationType(java.lang.String userName, java.lang.String parentName, java.lang.String annotypeName) Calls backend annotation service method addAnnotationType: protected java.lang.String: callMethod(java.lang.String methodName, java.lang.String[] args) Sends a message (calls specified method with specified arguments) and returns the response. It did not find the enum element specified since it was not available anymore. Proxy class creates the dynamic proxy class on the basis of given parameters.
