hi
My code is:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext();
LocalCommandServiceHome commandServiceHome = LocalCommandServiceHome) ctx.lookup("ejb/CommandServiceBean");

I'have librey jbossall-client.jar

I' have this error :
