  | Do you mean a db procedure kind of thing? That will have other significant disadvantages. So that query there looks fine.

Well... what I meant was that instead of querying for everything, loading everything, then performing a find in java code, shouldn't jBPM be creating a query criteria with the call that goes to the database? I mean, whats the point of loading everything in memory, and searching through it... databases are designed for tasks like these...

Though it appears that the queries are fired in a loop, but making query in that way actually will result in less number of queries (in fact no query to db most of the time). If you try to aggregate values and fire query then cache hit will not be possible most of the time.

I think is some misunderstanding here. I will code at the code again, and comment.

Thanks
