Hi I am facing a problem with accessing the JBOSS. according to the exception it seems to me --- log related exception. when I call the following code Hashtable env = new Hashtable(); | env.put(Context.INITIAL_CONTEXT_FACTORY, initCtxFac); | env.put(Context.PROVIDER_URL, providerUrl); | try { | | ctx = new InitialContext(env); | conFactory = (QueueConnectionFactory) ctx.lookup | (queueConFacLookupName); | | ----- | ----- exception details Exception in thread "main" java.lang.NoSuchFieldError: TRACE | at org.jboss.logging.Log4jLoggerPlugin.isTraceEnabled(Log4jLoggerPlugin.java:85) | at org.jboss.logging.Logger.isTraceEnabled(Logger.java:122) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:622) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:589) | at javax.naming.InitialContext.lookup(InitialContext.java:351) | at com.cognizant.util.ServiceHelper.initQueueService(ServiceHelper.java:153) | at com.cognizant.main.StartUp.<init>(StartUp.java:28) | at com.cognizant.main.StartUp.main(StartUp.java:46) I use jboss-4.2.1.GA version with JDK jdk141_05 version. I added jboss.jar,jbossall-client.jar,jboss-client.jar,jboss-system.jar,log4j-1.2.9.jar,log4j-boot.jar in my project library. Strange thing is that I run this same code with all other 3/4 windows XP system. OK But in another system with the same configuration I got the above mentioned exception. Can any body help me?
