Trying to invoke EJB services from WebLogic client

Hi,

trying to invoke EJB services on JBoss EAP 6.1 from a client running on WebLogic Portal 10.3.4, the console shows this error:

I already tried changing the log4j library inside the project, substituting many versions, from 1.2.14 to 1.2.17, but the problem seems to persist.
Any ideas?

Here the config properties:

Properties properties = new Properties();
properties.put("java.naming.factory.initial","org.jboss.naming.remote.client.InitialContextFactory");
properties.put("java.naming.factory.url.pkgs","org.jboss.ejb.client.naming");
properties.put("jboss.naming.client.ejb.context", true);
properties.put("java.naming.provider.url", "remote://x.x.x.x:4447");
InitialContext context = new InitialContext(properties);
