Hello, First, I am a complete novice with JBoss and Java. My task is to get a default configuration of JBoss up and running for use by another system that has its own applications. So I have minimal knowledge as yet of what I am doing. I am running on SUSE 10.1 SP2 and have Sun JDK 1.5.0 Update 17 installed. I have done the basic unpack of jboss-4.2.3.GA to /usr/local. Below is the first small portion of the trace I see when running bin/run.sh. I am not including the whole thing since it is very long. Suffice it to say that I get a lot of error trace dumps like the below. The server appears to be running after startup but responds with a blank page to http://localhost:8080/jmx-console. I am probably failing to do something simple but do not have a clue what. I would greatly appreciate any guidance on what is wrong.
