We thought its better to have all stuff in clojure rather than having java+clojure. But i can give it a try today.</p> <p>Thanks for your suggestion. will keep you posted.</p> <p>I'll close this out then Amir, thanx.</p> <p>I believe there is a way to access the the BoneCP connection pool directly and use it with java.jdbc as-is, however it is no longer an issue for the creator of this ticket.</p> Global Rank
