how do you return a file GDB from a python-tool based geoprocessing service

Hello,

I have created a python tool which

1) creates a new file geodatabase

2) extracts data from a Map Service via a REST call

3) creates a feature class in the fGDB created in step 1 via the JSONtoFeatures tool.

The tool works as expected when running ArcCatalog or ArcMap. I can publish the tool as a geoprocessing service with no problems, and then make calls against the GP service with no errors. If I publish the service as a synchronous process and then use the Services Directory browser to execute a task, I get a bunch of messages saying that everything was processed without error. However, the fGDB is not returned. If i publish the service as an asynch process and then submit the job, the "completed job" response gives me a URL, but when i browse to the URL, the response back is 'Invalid URL'.

In both cases (synch and asych), i can get on the server hosting the Service and see that the fGDB was created at the location i set for the arcpy,env.workspace (set as part of the execute method). If i don't set arcpy.env.workspace, the script wont run as tool.

What step(s) or settings(s) am I missing to have the GP service return the file geodatabase?

Thank you.

parameter definition
