I'm using JBoss 2.0 FINAL with TomCat and WebLogic's jDriver for SQL Server,
and would like to use JNDI to look up my database connection pool, and also
a few environment entries set in the web.xml file (via env-entry
elements).

> However, jndiView produces the following (note that my EJB named
AcctMaint is bound to the tree, but the Connection Pools and Env Entries are
not. Don't know if this is expected???):
InitialContext
+- TopicConnectionFactory
+- jmx:JP:rmi
+- QueueConnectionFactory
+- topic
| +- metrics
+- queue
| +- testQueue
+- ejb
| +- AcctMaint
+- invokers
| +- ejb
| +- AcctMaint
+- jmx
+- RemoteControl
> I have a test method to do JNDI lookups based on a key:
private static void lookup(String key)
{
try
{
System.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
System.setProperty(Context.PROVIDER_URL, "localhost:1099");
System.out.println("***** JNDI lookup : " + key);
InitialContext ctx = new InitialContext();
Object obj = ctx.lookup(key);
System.out.println("***** got it!");
System.out.println("***** value : " + obj.toString());
}
catch (Exception e)
{
System.out.println("***** Error getting: " + key + " - " +
e.toString());
}
}
> and the following calls to lookup() product the corresponding JBoss
console output:

> Questions:
1. Why does JBoss report the Connection Pools as bound, but they don't show
up using jndiView, and aren't in the JNDI tree on a lookup? I don't think
it's anything specific to the WebLogic driver, as the InstantDB and
DefaultDS Connection pools have the same problems, but I haven't modified
their config settings from the installation.
2. Why aren't the env-entry settings showing up either?
3. Once these issues are resolved, how do I go about getting my
EnvEntries/EJBs/Connection Pools bound to the recommended contexts of the
JNDI tree (e.g., java:/comp/env/myEnvSetting, java:/comp/env/ejb/myEJB,
java:/comp/env/jdbc/myConnectionPool)
I appreciate the help. Thanks in advance.
