The "JMX MBean Operation View" of JBOSS says

  | +- HelloBean (class: org.jnp.interfaces.NamingContext)
  |   |   +- remote-beanpackage.HelloBeanRemote (class: Proxy for: beanpackage.HelloBeanRemote)
  |   |   +- remote (class: Proxy for: beanpackage.HelloBeanRemote)
  | 
I suppose there is somewhere a problem with beanpackage.HelloBeanRemote, but where. Someone an idea?
