Starting JBoss…

…Ok, I’ve been having a whole load of problems getting JBoss to run.

It all started with me being stupid. If you’re having problems, check your environment variables first, people. I mean it.

Then I was getting this weird-ass error message that crashed the server before it even started and googling it only got me about 20 or 30 hits… All questions about the same problem as mine, with no answers (except for the above mentioned environment variables which didn’t cut it this time). I’ve been pulling my hair out about that one, especially since I get the same error on the University PCs. Turns out I wasn’t googling the right part of the exception, as I tend to do especially with very long ones.

So for people who can’t run ./run.sh because of the exception that starts this way:

[BasicMBeanRegistry] javax.management.MBeanRegistrationException: preRegister() failed: [ObjectName='jboss.remoting:service=NetworkRegistry', Class=org.jboss.remoting.network.NetworkRegistry (org.jboss.remoting.network.NetworkRegistry@290fd7f6)]
 23:32:16,395 ERROR [MainDeployer] Could not create deployment: file:/home/thingie/jboss-4.2.2.GA/server/default/conf/jboss-service.xml

Check further down — wayyyy down — if it states this in the last “Caused by:”

Caused by: java.lang.RuntimeException: Exception creating identity: dan:dan

…where “dan” stands for the name of your computer.
If that’s the case, it’s because the name of your computer can’t be resolved. Modify /etc/hosts accordingly (127.0.0.1 dan).

I don’t think this is going to cut it for me at University, but I’ll have a look anyway. Got it running on the laptop so it’s going to work out okay in any case.

…Now, to those beans I should have started to develop hours ago…
