I have a problem with c3p0. Last time I configured c3p0 as dataSource in application because Quartz Scheduler opened new connection for every check, now is ok but from this time application doesnt respond after about 30mins, sometimes more. There is no logs in catalina or application logs file. Other applications work normally on the same server. On this application I got 404. I returned to default Spring data source and removed configuration and everything works.
What can cause the problem ?

Can anyone explain to me whats the difference between hibernate.connection.autocommit and hibernate.c3p0.autocommit? Also there are another equal properties . Whats the difference? Also what happens if they are different which one will prevail?
According to the c3p0 documentation :
autoCommitOnClose Must be set in c3p0.properties, C3P0 default: false
The JDBC spec is unfortunately silent on what should happen to unresolved, pending transactions on Connection close. C3P0's default policy is to rollback any uncommitted, pending work. (I think this is absolutely, undeniably the right policy, but there is no consensus among JDBC driver vendors.) Setting autoCommitOnClose to true causes uncommitted pending work to be committed, rather than rolled back on Connection close.
As hibernate.c3o0.autocommit drives this settings, we can say that the difference is that hibernate.connection.autocommit is just like wrapping every query with begin transaction; and then commit.
Both are not recommended.
I want to connect to sql server in hibernate with windows authentication as the login methond. So my config as this but not connect to sql.
I also add sql maven dependency to pom.xml.
I try with comuter name and localhost in url connection but not connect to db.

Im using hibernate3 and springframework.
I want to set c3P0 Pool for hibernate.connection.provider_class but apparently LocalDataSourceConnectionProvider was set.
In Hibernate.log I see this:
[Level: INFO]Initializing connection provider:
org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider
I think org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider is hibernate default connection provider class for pooling and as I read it's wrong to use in production. Is that correct?
I want to set org.hibernate.connection.C3P0ConnectionProvider and manage pool connection with c3p0
This is my hibernate config:
<bean id="c3p0Datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">

Any suggestions?
I found some threads saying this was doable, but did not find specific instructions or config information.
I want to do this from Beanstalk as well: the app should get deployed to beanstalk with a config that points hibernate to the elasticache instance(s).
Yes, we were able to configure hibernate with 2nd level cache.. Not with beanstalk though.. This code should help you with it.

You would need the hibernate memcached jar as well
