Please do not misunderstand me, it is not a recomendation, it will not help too, but you can test this workaround at home:
1. before to return from "getConnection" pool sets "currentThread" for connection. 2. if !connection.getOwner().isAlive(), it safe to reuse connection. It must be safe to return the same connection for the same thread for the most of use cases too. It can help to hide problem and to crashe later, but it is not *common* way to solve problems . ----- Original Message ----- From: "Hope, Matthew" <[EMAIL PROTECTED]> To: "'Jakarta Commons Developers List'" <[EMAIL PROTECTED]> Sent: Wednesday, July 23, 2003 4:16 PM Subject: RE: [DBCP] AbandonedTrace - Connection Recovery > > > -----Original Message----- > > From: Glenn Nielsen [mailto:[EMAIL PROTECTED] > > Sent: 23 July 2003 13:52 > > To: Jakarta Commons Developers List > > Subject: Re: [DBCP] AbandonedTrace - Connection Recovery > > > > > > Hope, Matthew wrote: > > > I would disagree on one point.
