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'm using Hibernate integrated with Spring, please find bean for SessionFactory as below, all works well in Eclipse, however, sessionFactory can't be got after compiling to jar (mvn install), I mean the session got from the sessionFactory would be null.

The *.hbm.xml files are in src/main/resources, and I checked the classpath after the compiling and found nothing.
Could anyone help to give any advice about it ?
Thanks.
I found there are two hibernate-commons-annotations jars with different version in my classpath.
/Users/name/aa-o/target/aa-o-0.0.1-SNAPSHOT/doctor-o-0.0.1-SNAPSHOT/lib/hibernate-commons-annotations-5.0.0.Final.jar:/Users/name/aa-o/target/aa-o-0.0.1-SNAPSHOT/lib/hibernate-commons-annotations-3.5.6.Final.jar
In the running triggered in Eclipse, hibernate-commons-annotations-5.0.0.Final.jar works and all's well, I get the log
INFO [qtp1412752396-16] org.hibernate.annotations.common.Version - HCANN000001: Hibernate Commons Annotations {5.0.0.Final}
However, in the running triggered by shell script, hibernate-commons-annotations-3.5.6.Final.jar is chosen and system failed. And log is like
INFO [qtp1412752396-16] org.hibernate.annotations.common.Version - HCANN000001: Hibernate Commons Annotations {3.5.6.Final}
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 ?

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">

Please tell me what am I forgetting to add.
Your hibernate config file is using wrong parameter names. Correct param names are as below:
hibernate.connection.driver_class
hibernate.connection.url
hibernate.connection.username
hibernate.connection.password
hibernate.dialect
hibernate.show_sql
Correct your param names and try again.
EDIT: Refer this link for detailed list of param names: http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html
You can configure like this :
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="hibernateProperties">
<props>
<prop key="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</prop>
