persistence.

Answer 1

I had this same problem with the proprieties that I put in persistence.xml didn't affect c3p0.

Looking into http://www.mchange.com/projects/c3p0/index.html#configuration_files I tried to put an xml file named c3p0-config.xml and put it in WEB-INF/classes and it work perfectly.

Here is an example of a c3p0-config.xml file:

  
    con_test
    30000
    30
    10
    30
    100
    10
    200
