Hi, I have a problem when I want to run my application's jar, it's a standalone app and I don't have this problem when I run it into Eclipse.
I'm using Jboss 5.1.0GA, maven 2.2.1 and JDK 1.6.18.

PS C:\Workspace\hre\target> java -jar AppClient.jar
java.exe : javax.naming.NoInitialContextException: Cannot instantiate class: or
g.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoun
dException: org.jnp.interfaces.NamingContextFactory]

This is my code:

public Contexto() throws NamingException{

Properties env = new Properties();

// Try with a login that should succeed 
env.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
env.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
env.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming.client");
env.setProperty("java.naming.provider.url", "localhost:1099");

env.setProperty(Context.SECURITY_CREDENTIALS, "");

env.setProperty(Context.SECURITY_PRINCIPAL, "");
env.setProperty(Context.SECURITY_PROTOCOL, "java:/jaas/App");

this.ctx = new InitialContext(env); 
}

I added my server.log

If anyone can help me I would appreciate it.

Thanks
