Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 7.x
  • 6.x

Issue

• How to list the objects bound in the IIOP context in JBoss EAP 7

Resolution

Below is a standalone Java client example that uses the JDK com.sun.jndi.cosnaming.CNCtxFactory and invokes context.list to list out the contents of the IIOP naming context.

This follows up on the example in: How to expose an EJB via IIOP and call it in JBoss EAP 7 / 6

import java.util.Hashtable;
import java.rmi.RMISecurityManager;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.NamingEnumeration;
import javax.naming.NameClassPair;
import java.util.List;
import java.util.ArrayList;
import java.util.Properties;

public class JDKClient {

    public static void main(String[] args) throws Exception {
        // Setup security for stub downloading.  See conf/security.policy in
        // this project as well as this project's build.xml 'run' target for
        // additional required configuration.
        // Note this can be removed and use -Djava.security.manager instead when running the
        //  standalone java client
        if ( System.getSecurityManager() == null )
        {
            System.setSecurityManager(new RMISecurityManager());
        }

        System.setProperty("com.sun.CORBA.ORBUseDynamicStub", "true");

        listAllIIOPBindings("localhost");
    }

    private static void listAllIIOPBindings(String host) throws NamingException {
        InitialContext ctx = getIIOPInitialContext(host);
        String root = "";
        List<String> contexts = new ArrayList();
        contexts.add("");
        while(!contexts.isEmpty()) {
          root = (root.equals("")) ? contexts.remove(0) : root + "/" + contexts.remove(0);
          // list the context
          NamingEnumeration ne = ctx.list(root);
          // loop through context's children
          while(ne.hasMore()) {
            NameClassPair ncp = (NameClassPair) ne.next();
            String childName = (root.equals("")) ? ncp.getName() : root + "/" + ncp.getName();
            System.out.println(childName); System.out.flush();
            Object o = ctx.lookup(childName);
            // add any Contexts to the context list to search 
            if(o instanceof Context) {
              if(root.equals(""))
                contexts.add(root + ncp.getName());
              else
                contexts.add(root + "/" + ncp.getName());
            }
        }
       }
    }

    protected static InitialContext getIIOPInitialContext(String host) throws NamingException {
        Hashtable<String,String> env = new Hashtable<String,String>();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
        env.put(Context.PROVIDER_URL, "corbaloc::" + host + ":3528/JBoss/Naming/root");
        return new InitialContext(env);
    }
