      I am trying connect from Console Client Program to Process Engine:

      Properties props = new Properties();
      props.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");

      props.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");

      props.put("java.naming.provider.url", "jnp://localhost:1099");

      Context ctx = new InitialContext(props);

      ProcessEngine eng=(ProcessEngine)ctx.lookup("java:/ProcessEngine");


      but i catch NamingException: ProcessEngine not found.



      What i am doing wrong?

                Short stacktrace ;-)

                Ok, that would have been my second question, is it available anyhow, but you clearly state it is.

                Now I think of it, I remember something that things in the 'java:/' context are not available from outside the AS. I'm not sure though since I did not develop many things this way.

                  The jBPM service bound to the JNDI is not a remote component, like an EJB or Servlet. So you can inject it in other components deployed on the AS, but not from the outside (there is no spec for remote services - in plain Java).

                  You could use the remote CommandService, altough this is more low-level. Another option is wrapping the operations you need in an EJB/webservice/...
