[jboss-user] [EJB 3.0] - Re: interceptor metadata issue

[tterm]

The interceptors (org.jboss.aop.advice.Interceptor) are requested during an ejb3 method call. The client side interceptor code is the following: 

public class ExampleClientInterceptor implements Interceptor, Serializable {
  |    private static Logger logger =     Logger.getLogger(ExampleClientInterceptor.class);
  |    
  |    public String getName() {
  |       return "ExampleClientInterceptor";
  |    }
  | 
  |    public Object invoke(Invocation invocation) throws Throwable {
  |       logger.debug("Client: request");
  |       SimpleMetaData metaData = invocation.getMetaData();
  |       metaData.addMetaData("tag", "attr", "Hello JBoss;-)");
  |       Object obj = invocation.invokeNext();
  |       logger.debug("Client: response");
  |       return obj;
  |    }
  | }

If I do an EJB3 request I get allways this exception:

If I set the last parameter (Payload.KEY) for the addMetaData() method to 'AS_IS' then it works fine in jboss-4.0.4 and also 4.0.5. If the default payload key is MARSHALLED then it crashes with the ClassCastException.
