Hello all, I am using JBoss 4.2.1GA. When I tried to perform a Context.lookup(), I ran into a java.lang.NoSuchFieldError: TRACE exception in the following line: org.jnp.interfaces.NamingContext:622 | boolean trace = log.isTraceEnabled(); where log is of type org.jboss.logging.Logger.class. I think it's my client using the wrong jar file. I can see that there are several Logger in the following jar files: jboss-common-client.jar jbossall-client.jar jboss-common.jar jboss-ejb3-all.jar Which jar should I use? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067284#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
