we are setting up a web portal which allows users to submit jobs and

I don't know, so I've cc'd the gram-user mailing list.
No. GRAM does not gather this information from the local resource
managers (e.g. pbs) and make it available directly via GRAM. But,
TeraGrid is using OGSA-DAI to create a virtual DB on top of gram
auditing DB and TeraGrid's central DB (TGCDB).
Here is a paper on that:
http://www.globus.org/alliance/publications/papers/TG_GRAM_Auditing_and_LEAD_Gateway.pdf
Alternatively, is it possible to get the PBS job ID to use PBS
tools for
this task?
The "localJobId" was added as a resource property in GT 4.2.
http://www.globus.org/toolkit/docs/4.2/4.2.0/execution/gram4/developer/gram4-wsdl.html#gram4-rps-mejpt
But this was not available in ws gram in GT 4.0.
Yes. Assuming GRAM audit is enabled at the resource, you can query
the GRAM audit database to obtain the local_job_id (which is what the
PBS job ID is called in the gram_audit_table): For example, using the
GRAM Audit Tools, here's how you obtain the local_job_id given a
particular job_grid_id (GJID):
$ $GRIDSHIB_HOME/bin/get-audit-record --debug \
--GJID $GJID | grep local_job_id
http://globus.org/names/attribute/gram/audit_v1/local_job_id 12345
The output is a name-value pair for the "attribute" local_job_id.
The GRAM Audit Tools include a Java API to build your own if the
provided tools (such get-audit-record) don't do what you want.
Hope this helps,
Tom
