When you use Condor-G to submit a job via Globus, Globus assumes it's a
regular executable. When Globus submits the job to the remote Condor pool,
it submits it as a vanilla universe job. Globus doesn't do any special
handling for java jobs. If you have a recent version of Globus installed
on surya, you can set attributes in the submit file that Globus uses to
submit the job to Condor. For example, you can make the remote job be
submitted as a java universe job by adding the following to your Condor-G
submit file:

GlobusRSL = (condor_submit=(Universe java))
