I had trouble finding information when I was struggling with a
'Resource key is missing' error this week. Since I have found the
solution I thought I would post it to this mailing list for others to
find.
Essentially, when I was submitting a GT4 GRAM job I was encountering
the following error:
org.apache.axis.axisfault : java.rmi.remoteexception: job creation
failed.; nested exception is:
org.globus.wsrf.invalidresourcekeyexception: resource key is missing
Most of my code followed the sample code, except that I was loading
my proxy credentials manually from a proxy file in a non-standard
location.
I eventually came to the realization that not all GSSCredential
objects are the same. Even though I had loaded my GSSCredential, it
needed to be processed by the ExtendedGSSManager in order to contain
the correct resource key for job submission.
The working code ended up being:
//credentials
GSSCredential credential;
GlobusCredential globusCredential;
globusCredential = new GlobusCredential
( this.proxyCertLocation );
credential = new GlobusGSSCredentialImpl( globusCredential,
GSSCredential.INITIATE_AND_ACCEPT );
//set default credential to prevent accidental loading of
default globus proxy files
GlobusCredential.setDefaultCredential(globusCredential);
//(processing through the extendedgssmanager)
ExtendedGSSManager manager = (ExtendedGSSManager)
ExtendedGSSManager.getInstance();
credential = manager.createCredential
(GSSCredential.INITIATE_AND_ACCEPT);
globusCredential = ((GlobusGSSCredentialImpl)
credential).getGlobusCredential();
//set security
HostAuthorization iA = new HostAuthorization();
ClientSecurityDescriptor secDesc = new
ClientSecurityDescriptor();
secDesc.setGSITransport(GSIConstants.ENCRYPTION);
secDesc.setAuthz(iA);
secDesc.setGSSCredential(credential);
secDesc.setProxyFilename(this.proxyCertLocation);
((Stub) factoryPort)._setProperty
(Constants.CLIENT_DESCRIPTOR, secDesc);
Calendar cal = Calendar.getInstance();
cal.add(java.util.Calendar.HOUR,50);
//generate unique ID for referencing job later
String uuid = UUIDGenFactory.getUUIDGen().nextUUID();
CreateManagedJobInputType jobInput = new
CreateManagedJobInputType();
jobInput.setJobID(new AttributedURI("uuid:" + uuid));
jobInput.setInitialTerminationTime(cal);
jobInput.setJob(jobDescription);
CreateManagedJobOutputType createResponse =
factoryPort.createManagedJob(jobInput);
EndpointReferenceType jobEndpoint =
createResponse.getManagedJobEndpoint();
I hope this information might come in useful for somebody else.
Although I understand it is not common to load proxy credentials from
a non-standard location.
