Re: [Condor-users] How to find Java bin Path in different machines of condor

[Matthew Farrellee <matt@xxxxxxxxxx>]

Another possibility is to ask your sysadmins to add STARTD_EXPRS = JAVA 
to their execute node configs. You can then use $$ to reference JAVA 
from the ad of the machine your job is running on, e.g. arguments = 
script $$(JAVA).

Best,
