Retrieving results of asynchronous export job

ScottAC

Hi all - I'm using AppExtender web service (v5.3) to retrieve documents stored in our repository and display them as PDFs on a web page.  I've successfully established a user session, queried for the desired document, and kicked off the job to export the document as a PDF file (using the exportDocumentPagesByRef).  The documentation I have states that the results of this job need to be obtained asynchronously via a call to GetExportDocumentPagesResult using the job key returned by exportDocumentPagesByRef.  Everything works fine, and I can see the actual exported document on the file system of our server.  But when I call exportDocumentPagesByRef and pass it the job key, I get an error claiming I'm not logged in.  So I can't tell which sub directory in the output directory contains the file I just exported.

I'm trying to use the same session ID under which I performed the original query and the export itself.  As far as I can tell, that session should still be valid - leastways I don't logout until after the GetExportDocumentPagesResult fails.  Do I need to login again to establish a new session in order to get the job results?  Or am I missing some step somewhere?

Apologies to all, pressed enter too soon.  Rest of the story is sometimes the call does in fact work, but returns an empty AxStringArray object (empty meaning I get a valid XML AxStringArray object, but no attributes or nodes within it to identify the exported file).  It's only after retrying one or more times that the call suddenly fails.  Any ideas would be appreciated.
