I am using jboss 4.0.5 GA.. Please somebody help me please:

Context context = new InitialContext();
operacionesRHRemoto operacionesRHRemoto = (OperacionesRH) context.lookup("RHumanosEAR/"+OperacionesRH/remote);

and:

  +- RHumanosEAR (class: org.jnp.interfaces.NamingContext)
  |   +- EmpBean (class: org.jnp.interfaces.NamingContext)
  |   |   +- local (proxy: $Proxy179 implements interface em.facade.EmpBeanLocal,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
  |   |   +- remote (proxy: $Proxy178 implements interface em.facade.EmpBeanRemoto,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject)
  |   +- DepBean (class: org.jnp.interfaces.NamingContext)
  |   |   +- local (proxy: $Proxy183 implements interface de.facade.DepBeanLocal,interface org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
