Hi,
I am unable to reference your old email in the gt-user archives, but I am
curious that your proxy credential affected access of GRAM job with a
resource key missing exception. So if you comment out the following code
from your snippet, you see a resource key not found exception?
> //(processing through the extendedgssmanager)
> ExtendedGSSManager manager = (ExtendedGSSManager)
> ExtendedGSSManager.getInstance();
> credential = manager.createCredential
> (GSSCredential.INITIATE_AND_ACCEPT);
> globusCredential = ((GlobusGSSCredentialImpl)
> credential).getGlobusCredential();
In the security framework, when we load credential from a file, we use only
the GlobusGSSCredentialImpl constructor for creating the relevant credential
and we don't create a user credential using the ExtendedGSSManager. So I am
surprised about this fix.
Also, just to confirm, in both cases were you using the following utility or
equivalent to create the EPR to the GRAM factory service?
EndpointReferenceType factoryEndpoint
= ManagedJobFactoryClientHelper.getFactoryEndpoint(factoryUrl,
factoryType);
ManagedJobFactoryPortType factoryPort
= ManagedJobFactoryClientHelper.getPort(factoryEndpoint);
In your SOAP message header, did you see the resource key was missing in the
previous case?
Thanks,
Rachana
