Subject Re: JNDI lookup in Tomcat
Date Thu, 09 Oct 2008 13:15:58 GMT

In a servlet listener for my webapp, I'm using this:

    public void contextInitialized(ServletContextEvent aArg0)
    {
        System.setProperty(Context.INITIAL_CONTEXT_FACTORY,   
            "org.apache.openejb.client.LocalInitialContextFactory");
        System.err.println(">>>>>>> FULL JNDI TREE FROM STARTUP");
        try {
            InitialContext ic = new InitialContext();
            listContext("",ic);
        } catch (NamingException e) {
            System.err.println("Could not list tree."+e);            
        }
        System.err.println("<<<<<<< FULL JNDI TREE FROM STARTUP");  
             
    }

    private static final void listContext(String s, Context c) throws
NamingException
    {
        NamingEnumeration<NameClassPair> pairs = c.list("");
        for (; pairs.hasMoreElements();)
        {
            NameClassPair p = pairs.next();
            System.err.println(s+"/"+p.getName() + " " + p.getClassName());
            Object o = c.lookup(p.getName());
            if (o instanceof Context)
            {
                Context child = (Context) o; 
                listContext(s+"/"+p.getName(), child);
            }
        }
    }

And here's what I get:
/. java.lang.String
/openejb org.apache.openejb.core.ivm.naming.IvmContext
/openejb/ConfigurationInfoBusinessRemote
org.apache.openejb.core.ivm.naming.Busi
nessRemoteReference
/openejb/DeployerBusinessRemote
org.apache.openejb.core.ivm.naming.BusinessRemot
eReference
...and then other contexts created by my MDB/SB.

I don't see any /openejb/TransactionManager there.
