Would it be a multi-threading problem, another user moves cursor to next row of the ResultSet?

How can turn on the validation which checks for a good connection before returning. I guess i need to setTestOnBorrow(true). Do I need to do any thing else? We actually have automated JTest which checks for all closed connections. So that's what makes me certain that connections are all closed properly. What i did is that i made only one connection available to the pool. and when i'm the only user, things work fine even with one available connection. -----Original Message----- From: Miller, Jason [mailto:[EMAIL PROTECTED] Sent: Thursday, February 27, 2003 2:57 PM To: 'Struts Users Mailing List' Subject: RE: [OT] DBCP Pool Closed connection problem I had this problem once. At the time, I was positive everything was closed correctly, but it turned out at one point, where I was unwrapping the connection, I had closed it. This inadvertently caused the pool to be exhausted. This occurred before I had a quality check on my connections, so it didn't replace the closed ones. Still, check exhaustively before you say you are positive all closings are correct. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: Thursday, February 27, 2003 3:52 PM > To: [EMAIL PROTECTED] > Subject: [OT] DBCP Pool Closed connection problem > > > Hi, > I'm using commons DBCP in conjuction with STRUTS. > When a lot of users start using our application, we > start getting a > lot of exceptions related to Connections, like "Exhausted > Resultset" or > "Connection is Closed".
