If I use Servlet to invoke the function of  my mbean, and the function has a    user-defined-class parameter, not int,string or else. It will throw a IllegalArgumentException: argument type mismatch. But from other way it runs correctly.

Anyone who met this problem before?


Example code:
RMIAdaptor mBeanRMIAdaptor = (RMIAdaptor) ic.lookup("jmx/invoker/RMIAdaptor");
ObjectName TestObjectName = new ObjectName("......");
            String[] sigs = { "test.TestObj" };
            Object[] params = { testObj };
            String result = (String) mBeanRMIAdaptor.invoke(TestObjectName, "testMethod", params, sigs);

If you change the parameter to String , Int or other java type, it runs correctly.
Or if you invoke it from a java application, it runs correctly too.
