[JNDI/Naming/Network] - What is happening?... DefaultDS?
by randall＠fieldshome.com
Greetings Gurus!
I am having difficulty referencing the DefaultDS from a
client running outside the JBoss JVM. Any advice or examples would be greatly
appreciated. I am running JBoss version 4.0.5GA. I eventually want to load
and use the datasource in the client application. For simplicity of example,
I set up a default JBoss install. It seems that I do not have access
to anything in the java: context from outside the JBoss JVM. Are there
security constraints that need to be modified?
Here is my source code:
---
import java.util.*;
import javax.naming.*;
public class JNDI {
public static void main(String[] args) {
try {
Context ic = new InitialContext();
// Print the environment settings
System.out.println("Printing environment keys:");
Hashtable hash = ic.getEnvironment();
Enumeration keys = hash.keys();
while (keys.hasMoreElements()) {
Object key = keys.nextElement();
Object value = hash.get(key);
System.out.println(key + "=" + value);
}
// We can see several bindings, just not the ones we need
System.out.println();
System.out.println("Printing bindings in jmx:");
NamingEnumeration b = ic.listBindings("jmx");
while ( b.hasMoreElements() ) {
Object key = b.nextElement();
System.out.println(key);
}
System.out.println();
System.out.println("Get the default datasource:");
// Both of the following lines choke:
// b = ic.listBindings("");
// Context compEnv = (Context) ic.lookup("java:/DefaultDS");
}
catch (Exception e) {
e.printStackTrace();
}
}
}

The first few lines of output look like:
Printing environment keys:
jnp.parsedName=
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
Printing bindings in jmx:
invoker:
org.jnp.interfaces.NamingContext:org.jnp.interfaces.NamingContext@a4e743
rmi: org.jnp.interfaces.NamingContext:org.jnp.interfaces.NamingContext@4aeb52

The "listBindings" call throws the following stack dump:

I am certain that the DefaultDS is up and running since the out of the box
examples work, however they are all running inside JBoss. I have tried many
many things to no avail.

I really want to use JBoss, and eventually lend my support to the efforts
surrounding what appears to be an awesome project, but I am beginning to
have doubts in my choice as I have been trying to get this to work for
some time. What am I doing wrong?
I am completely confused. Please advise.
Thanks,
Randall

[Management, JMX/JBoss] - Aspect in XMBean
by bossy
Hi,
I need to create an aspect that can be managed by JMX. The idea is to use the aspect to obtain some stats(by intercepting calls) and to use JMX console to retrieve the stats.
I created an XMBean and I added methods wich I use as advices.
Everything almost works with one exception - it seems that AOP and JMX create their own instances of the class. Aop intercepts the calls I make and updates the stats, but the XMBean values of the same stats remain the same ( null in my case).
I tried to use separate XMBean and aspect classes, but the problem is that in order to use the XMBean methods to update my stats, I have to expose them and once i do this - they are available to the users in the JMX console.
My question is - is it possible to do write an Ascpect XMBean and if so - where should I look for more details.
Thanks in advance.
