jobrun.exe not triggering jobs when logged on with lhc.jar

Hi!

We have created a service in WAS to inteface to lawson.  It logs on using lhc.jar and then creates a gl165 job using ags calls and runs it using jobrun.exe.

For some reason, in unix server 1, which has the WAS server and the Lawson Apps, its able to create the job but not able to trigger the job using jobrun.exe.  When I point the interface to the 2 other lawson productline with 2 other productline in the the same server unix server 1, the same error happens.

Then if I point the service in unix server 1 to a productline in unix server 2, it is able to create the job and trigger the job.

using IE browser, the jobs can be triggered in all productlines server 1 and 2.

Would you know of any particular reason why the submit from the Service can't trigger the jobs using jobrun.exe when logged on using lhc.jar? 

Thanks in advance.
