last couple of weeks I'm starting to get the above error when deploying th=

I have copied another developer's JBOSS 6.1 code to my computer and the iss=

The javasource code has no errors.  I'm trying to run jboss from the =
command prompt but I get a java_home is not set even though it is and it st=
art's up in MyEclipse without a problem.  Below is the complete except=

the way, the below exception is constantly repeated as though it's trying =
