For a Java app outside of a J2EE container, which connection pool library is the best?
I was using c3p0 along with DataNucleus/JPA and it was easy to switch to BoneCP. Practically all I had to do is change the DataSource configuration in the Spring context file.
As far as I saw the BoneCP benchmarks are really good: http://www.databaseskill.com/2282333/, http://jolbox.com/benchmarks.html
