I didn't check if it's working, because I cannot even run JBoss on my linux machine. So you can check this site: http://www.opencrx.org/opencrx/1.7/JBoss-4/html/c382.htm maybe it will help.
How did you make it run under linux. I'm using the same version as you do. I used the installer jar and I selected EJB3 all this with JDK1.5_05. Can you tell me what you did?
Can you run jboss on the console? My installation was not through the jar installer. I used the zipped up version. I downloaded the EJB3 zip file and made the appropriate changes.
I am sorry, but it seems to be a JBoss problem, because JBoss works fine under the console mode, and it seems to work fine as a service except that the web page stops loading after a while. I don't know what it could be as I followed the instructions.
