Hi,

I loaded the data you mentioned in another thread and run the query using Jena API. I got one answer for the query without seeing any problem.
I also checked the output you uploaded. It is unclear why the original query failed. There was no exception printed out.

Could you please run the query using Jena API (instead of Joseki) and then send the stack trace?

Thanks,

Zhe Wu

Zhe,
This query is returning, the problem is that it takes a remarkably long time. It's taking nearly 4.5 seconds when most finish in tens or hundreds of milliseconds. When I looked into the logs to investigate the possible problems, I discovered that this query is responsible for over 8000 SELECT statements being sent to the database.

Making this query via the Jena API causes the same behavior.

The code I'm using to submit the query along with the output that is printed to standard out are bundled here

In my test, I only see one query. Please email me your contact information so that I can give you a call.

Thanks,

Zhe Wu

Awesome, your offline help fixed it. Turns out I had the wrong sdordf.jar. The rest of the patch was applied properly, but I had missed that step apparently. This query is executing very quickly now, no flood of SELECTS. Thank you.
