Firewall issues? I'm not familiar with how ScrumWorks packages Tomcat.
Have you tried swapping ports? Running JBoss on 8000 and Apache on 8080, to see if the problem follows?
There is not any Firewall on the machine.
I do not think that the reason is in the port ? Apache was working on this port (8080) just before ScrumWorks, and I did not have any problems.
This is happening on Windows and the status of Apache does not influence the behavior of ScrumWorks.
ps sorry for time-out, I was in a trip.
