I’m trying to deploy a web app on JBoss 4.0.5.GA, but get the following error.
What’s frustrating is that I’m not even exporting log4j.jar. I’m also using JBoss’ version (see .classpath below)

<classpathentry kind=”lib” path=”C:/sw_dev/java/j2ee/lib/selenium-remote-control-0.8.1/server/selenium-server.jar”/>

This is your offending entry (read your error, higher up). It looks like for build purposes you are including a server-JAR in your build path. The only problem is that when you then deploy the project, you are re-deploying this server JAR back to itself, and causing the load violation. You will either need to not include this in your path, or adjust the deployment rules under your project properties then MyEclipse > Web> Deployment, to not deploy that *type* of JAR.
