I'm accessing an EJB 3 business interface on jboss from a standalone client by

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

Test test = (Test) ctx.lookup("TestBean/remote");

This works, but the lookup produces the warning:

log4j: WARN No appenders could be found for logger (org.jnp.interfaces.TimedSocketFactory)
log4j: WARN Please initialze the log4j system properly

Has anybody an idea what I have to do in order to get rid of these warnings ?

Any help is appreciated. Thanks.
