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 :

it's POM :
[code]

[/code]
this is my first test client, the one without maven wich has no problem whatsoever to speak with the EJB

this is my second test client, using maven, it cannot speak with the EJB, all I'm getting is :
[code]
Context lookup finished
Exception in thread "main" java.lang.ClassCastException: javax.naming.Reference cannot be cast to com.thongvan.mp.MyFirstMavenEjb.TestMavenEjb
at com.thongvan.mp.TestClientMavenEjb.App.main(App.java:27)
[/code]

It's POM :
[code]
<project xmlns=" http://maven.apache.org/POM/4.0.0 http://maven.apache.org/POM/4.0.0" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"

<artifactId>MyFirstMavenEjb</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
[/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 :
