Could anyone please give me an idea of what is happening? I searched, but couldnot find an effective answer. My jboss version is 4.0.5. Eclipse Indigo and java 6

I was trying to install a new server into eclipse and then when i tried to start it I got this error. My Eclipse and code was in use for so long and did not have any issues. I have currently no projects put in my server. I just tried starting it and got this error. Am I missing any configurations?

Answer 1

I missed to quote my server VM arguments. just missed to put the VM arguments in double quotes and this happened.
