Hi, here is my problem, I made an EJB with maven and 2 test clients,
* a test client without maven, only added jnp-client and the EJB to it's class path, work like a charm
* a test client using MAVEN, added the EJB through the POM and jnp-client, does not work
this is my EJB :
[img] http://img11.hostingpics.net/pics/480421EJB1.png http://img11.hostingpics.net/pics/480421EJB1.png[/img]
it's POM :

this is my first test client, the one without maven wich has no problem whatsoever to speak with the EJB
[img] http://img11.hostingpics.net/pics/974963EJB0.png http://img11.hostingpics.net/pics/974963EJB0.png[/img]
this is my second test client, using maven, it cannot speak with the EJB, all I'm getting is :
[code]
Context lookup finished

[/code]
Both clients have the same main :
[code]
public static void main( String args[] ) throws NamingException
{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );
Context ctx = new InitialContext(env);
System.out.println("Context lookup finished");
TestMavenEjb proxy = (TestMavenEjb)(ctx.lookup("TestMavenEjbBean/remote-com.thongvan.mp.MyFirstMavenEjb.TestMavenEjb"));
System.out.println(proxy.getClass());
System.out.println("do something!");
proxy.doSomething();
}
[/code]
So, anybody has even the slightest idea about why the maven test client is not working?
Jboss 5.1.0.GA
Eclipse indigo
Maven 3.0.4
Also I did some poking around by printing a toString on both context lookup here is what I got :
