Problem acessing business mehod of Session Bean
Hi,
I am trying to access a business method of a stateless session bean, but receive the exception:
java.lang.NoSuchMethodError: org.jboss.aop.joinpoint.MethodInvocation.([Lorg/jboss/aop/advice/Interceptor;JLjava/lang/reflect/Method;Ljava/lang/reflect/Method;Lorg/jboss/aop/Advisor;)V

This my Session Bean and its business interface:
@Stateless
public class LogarFacadeSessionBean implements LogarFacadeRemote{
public LogarFacadeSessionBean(){
}
public BancarioVo mymethod (String login, String senha) throws SQLException, Exception{
...
}
}
@Remote
public interface LogarFacadeRemote{
public BancarioVo mymethod (String login, String senha) throws SQLException, Exception;
}
This is my client:
public class LogarAction extends DispatchAction{
public ActionForward autenticarUsuario (ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws SQLException, Exception{
InitialContext context = new InitialContext();
String lookup = LogarFacadeRemote.class.getName();
LogarFacadeRemote logar = (LogarFacadeRemote) context.lookup(lookup);
BancarioVo bancarioVo = logar.mymethod (login, senha);
...
}
}
It passes normally til the line
LogarFacadeRemote logar = (LogarFacadeRemote) context.lookup(lookup);
but when I invoke the method
BancarioVo bancarioVo = logar.mymethod (login, senha);
it throws the exception above.
Anybody knows what is causing this error??
What else should I have in my Session Bean?
Is missing any Annotation (@BusinessMethod, @Interceptor...)?
What about the callback methods?
Are they necessary?
Where should I declare them?
I am doing exactly the way tutorials recommends!
Thanks, Guilherme
