Hi everyOne:
openJpa version :2.2.1
i want to use c3p0 as my datasourcePool
this is my configuration fragment
<property name="openjpa.ConnectionDriverName"
value="com.mchange.v2.c3p0.ComboPooledDataSource"/>
<property name="openjpa.connectionProperties"
value="driverClass=com.mysql.jdbc.Driver,jdbcUrl=jdbc:mysql://127.0.0.1:3306/test?zeroDateTimeBehavior=round,user=root,password=root,initialSize=10,maxIdle=20,minIdle=5,maxActive=50,MaxWait=10000,timeBetweenEvictionRunsMillis=3600000,minEvictableIdleTimeMillis=18000000"/>
