Configuring remote context

[jenspopp]

Hi,

I want to access a session bean on a remote server via the remote (home) interface. Is there a way to set the context (servername/port) at deploytime (e.g. in an xml conf file) and do a jndi lookup on the local Server?

Thanks

Jens

you need jndi properties on remote client

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://hostname:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

Hope that helps.
Amit.

jenspopp,

Did you mean that you want to perform the lookup from a session bean on one JBoss instance to another JBoss instance or did you mean that the client is running outside of JBoss?

Hi,

thanks for the fast reply. I have to instances of jboss running on different servers. I want to access a session bean (user management) on the remote server from my own server. I'd like to configure the hostname/port of the remote server during deploytime.

Thanks

If you have a look at the administrators guide available from the documentation link above there is an MBean described called 'ExternalContext' in chapter 3.2.6.1.

I have never tried using the MBean so can not say how well it would work but basically the bean allows you to bind a remote JNDI context in your local context, using this combined with an ejb-ref may meet your needs.

Hi,

I think there is a solution using the jboss.xml file. I have defined the UserManagement as an external ref in ejb-jar.xml:

<ejb-ref >
 <ejb-ref-name>ejb/UserManagement</ejb-ref-name>
 <ejb-ref-type>Session</ejb-ref-type>
 <home>session.interfaces.UserManagementHome</home>
 <remote>session.interfaces.UserManagement</remote>
 <ejb-link>UserManagement</ejb-link>
</ejb-ref>

I also defined in the jboss.xml:

<ejb-ref>
 <ejb-ref-name>ejb/UserManagement</ejb-ref-name>
 <jndi-name>jnp://remote:1099/ejb/UserManagement</jndi-name>
</ejb-ref>

or:

<ejb-ref>
 <ejb-ref-name>ejb/UserManagement</ejb-ref-name>
 <jndi-name>jnp://remote:1099/UserManagement</jndi-name>
</ejb-ref>

When I try to deploy I get always the error:

org.jboss.deployment.DeploymentException: Failed to resolve ejb-link: UserManagement make by ejb-name: ejb/UserManagement

No matter if the remote server is running or not. If I deploy it in the same ear file (on the same server) it runs. It seems the jboss server ignores the jndi-name tag. Do I have to configure something else?
