I'm new to the list ... I'd like to know where can i found the source of the jdbc driver for postgresql (the jdbc7.0-1.2.jar) --hermann PS : Is anyone here using postgres with jBoss (minerva as pool connection manager)? I really have a strange problem : when i perform "update" query on the base via a pooled connection from minerva, it is throwing exception, while everything works fine with "insert" or "select". I wonder if something in the driver (like auto-commit or anything else) may cause this problem. My guess : Auto-commit is set to true in a "update" query, so that when minerva tries to end the transaction by commiting it, exceptions get thrown. ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
