Reflection with Beans

[Eyal Hirsch]

Hi all,
 I'm using reflection in order to
call an unknown bean at developement
time. I'm able to get the home interface
and call the create method using reflection.
However when I try to call the desired
method I get an exception. Below is
the main code i use :

  home = ( EJBHome )javax.rmi.PortableRemoteObject.narrow( objRef,
 ejbMetaData.getHomeInterfaceClass() );
  classData = home.getClass();
  try {
     methodToInvoke = classData.getMethod( "create", methodCreateTypes );
     EJBObject beanInstance = ( EJBObject )methodToInvoke.invoke(
  home, argsCreateMethod );

     // These two lines won't work either.
     // Object narrowObj = javax.rmi.PortableRemoteObject.narrow(
  beanInstance, ejbMetaData.getRemoteInterfaceClass() );
     // classData = narrowObj.getClass();

     classData = beanInstance.getClass();
     // The above call returns my _xxx_stub class

     // The following line causes the NoSuchMethodException exception
     Method methodToInvoke = classData.getMethod(
 mappedData.sMethodName, methodBeanTypes );
     return ( ( String )methodToInvoke.invoke( beanInstance, argsBeanMethod ) );
  }

 If i put a debug code which prints the available
methods in beanInstance I can see the desired
method with the desired parameters, again using
reflection, so the method is there, but i just can't
call it. The code is called from a servlet, the same
code works fine when called from a regular class,
does this makes sense ?

Any ideas ?

Thanks in advance,
  eyal.
