    Problems debugging JBoss source

    Adam Pritz Newbie

      JBoss is new to me and I am evaluating it for a project.

      I have written a very simple JMS Server inside an EJB and attempted to deploy the EJB in JBoss by placing JAR files in the default server deploy directory. In doing so, I receive the following Exception, which is entirely inside of JBoss code, but it could no doubt be caused by my code. I thought I had seen that this error could be fixed by upgrading to JBoss 4.0.3SP1, so I upgraded from 4.0.3, but this did not help.

      So, I then figured I'd try to download the JBoss source and debug/possibly fix the problem myself. Well, I was unable to connect anonymously to the anoncvs server through Eclipse (using a pfs file and HowToDevelopJBossWithEclipse Wiki) and also WinCVS. They both return Connection Refused errors. Using WinCVS from the command line, I was able to reach the anoncvs server but when prompted for the password and hitting Enter (for blank password) the connection gets refused.

      I would greatly appreciate assistance from someone with more JBoss experience. I am more than willing to debug myself if someone can just help me get the JBoss source.

      Thanks,
      Adam

          Finally, I was able to fix this Exception. It was because I had no LocalHome interface. I just hadn't configured XDoclet to generate this interface. That fixed the StringIndexOutOfBoundsException. It would have been nice if Jboss could have caught this error and provided good feedback, rather than throwing the Exception that I saw.
