Re: [Condor-users] Condor Java problem

["M Swain" <MT.Swain@xxxxxxxxxxxx>]

Hi David

I am suffering from the same Java problem that was discussed about a month ago: java can be seen with condor_starter -classad, but not with condor_status -java. If I run the script as suggested then the libjvm.so can't be found.
 
The only difference is that I am not starting condor with init. If you made any progess with this problem, or if anyone else has any further suggestions, I would very much like to hear from you.

Cheers

Martin

Thanks for the suggestion.  It does seem to be an issue with the
environment.  Now I just have to figure out exactly what the issue might
be.  I'm starting Condor with init, but the environment dumped from the
condor_starter wrapper looks the same as the usual root environment,
from which condor_starter -classad works correctly.  I'll keep digging.
maybe I missed a difference.  For now, I'm getting the following from
the wrapper's attempt to start Java:


  Error occurred during initialization of VM
  Unable to load native library: libjvm.so: cannot open shared object
file: No such file or directory
