Hi folk,

Afer 8 hours of inactivity (ex. during night) connection close and my application stop to work...

Anyone know how to obtain the same as "jdbc:mysql:/localhost/mydb?autoReconnect=true" with oracle jdbc driver? Assuming actually, even with MySql, using the autoReconnect parameter is not recommended (http://www.theserverside.com/news/thread.tss?thread_id=24137#111947).

I don't use Hibernate connection pool but DBCP (with tomcat) and this not help:
"<property name="connection.autoReconnect">true</property>": after 8 hours of inactivity I get "connection error" exception.

Can c3p0 help?
<property name="c3p0.idle_test_period">100</property>
Is c3p0 really "enterprise ready"?

Here my hibernate.cfg.xml file:



I use a JNDI resource with this "context.xml" configuration:



but it doesn't seem to work!
From Tomcat LOG:




I'm discouraged but I cannot think that a so basic thing is too difficult to setup! (

Have a look at this, especially the validationQuery, testOnBorrow, testWhileIdle, timeBetweenEvictionRunsMillis and the related properties.
