	I'm not familiar with the specifics of our SOAP implementation, 
but the problem here may be that you're trying to get the job ad before 
you've finished building it.

	As I understand it, all the newJob() does -- despite the name -- 
is allocate a new procID.  At that point, the job ad is almost entirely 
empty.  (For non-SOAP connections, the job may already have an Owner 
attribute, because the connection itself authenticates as a particular 
Owner.)

	The examples for SOAP I've seen either build a job ad by hand or 
call createJobTemplate() to generate a job class ad.  You then submit the 
job ad you built and commit the transaction.  To continue your example:

> Transaction transaction = scheduler.beginTransaction(30).getTransaction();
> Integer clusterId = scheduler.newCluster(transaction).getInteger();
> Integer jobId = scheduler.newJob(transaction, clusterId).getInteger();
ClassAdStructAttr[] jobAd = { ownerAttr, cmdAttr, argsAttr };
schedd.submit(transaction, clusterId, jobId, jobAd);
schedd.commitTransaction(transaction)

where 'ownerAttr', 'cmdAttr', and 'argsAttr' are (example) ClassAdStructAttr
objects created however you find convenient.

> Is there a way to define a default job-owner for SOAP?

	If I recall correctly, you can configure HTCondor to generate an 
Owner attribute for SOAP by using SSL and the HTCondor mapfile.

	There's a fully-worked example at the following URL (although it 
uses Axis rather than JAX-WS):

	If you still see problems (or if you try with HTCondor 8.4 and it 
works), please let us know, and we'll take a closer look to see if we 
accidentally broke something.  Thanks!
