Hopefully I found the correct sub-forum in which to post my question (there were a ton of them, forums, that is). I have only one question, and that is I need some assistance in trying to figure out how to troubleshoot a problem. I inherited a jboss application and have followed the directions provided to me. I have apache running on port 80 just fine. I have jboss-4.2.3.GA-jdk6 installed and running on port 8080. I can compile and deploy my web application via "ant ear" just fine. I start jboss, and everything _looks_ fine. I can provide my output and the log if needed (I just didn't want to flood the forum with this if it wasn't necessary. When I browse to http://localhost:8009/myproj, the browser seems to just sit and try to load the thing. The output from jboss shows: ERROR [AjpMessage] Invalid message recieved with signature 18245 I am not sure even where to start looking. Can anyone help?
