I found it rather hard to find this thanks to the generic words “web” “services” and “console”, but JBoss has a handy little console for their web services (if you use their implementation). It is available when JBoss is running at — http://{server-name}/jbossws — and can tell you what services are available, how many times they’ve been called, etc.
Also worthy of note is the location of the default homepage for JBoss:
${JBOSS_HOME}/server/default/deploy/jboss-web.deployer/ROOT.war
Within that dir, you find index.html and other resources that you can modify or remove. The best thing to do is to change which app hosts your ROOT context, but that’s a different story.
