4. Information about DBCP connection pooling    forum.hibernate.org

PDF version: http://hibernate.org/tmp/Jakarta_Pooling.pdf I'm not really surprised. I've experienced "out of memory" and closed/shared connections with Tomcat and DBCP regularly. Because this was only in development, I simply restarted the whole mess and continued, because there's no point in debugging Jakarta software. You won't get anything done. My personal advice is and has been for a long time: Don't use anything ...

8. DBCP 1.2 connection pool trouble    forum.hibernate.org

I'm having some trouble using the new DBCP 1.2 with hibernate2.1.3, in that the connections do not seem to return to the pool. Every call to hibernate effectively opens a new connection, and of course this exhausts the database's resources. Reverting to DBCP1.1 and Pool1.1 fixes the problem, but I was hoping to use DBCP1.2. Perhaps there are some properties in ...

12. Please helping in understanding datasource ..c3p0? DBCP?    forum.hibernate.org

Ok, I'm upset so I hope it doesn't come off that way too badly in this question. The docs and the JPA with Hibernate book are incredibly confusing on this issue of datasources. Google doesn't help much either since many things that come up are outdated or when I've seen this question asked, it seems to remain unanswered. I understand I ...
