MySQL4.1:

NO

DEBUG:

My hibernate.cfg.xml is:

Code:

<hibernate-configuration>
    <session-factory>
      <property name="hibernate.connection.provider_class">org.hibernate.connection.ProxoolConnectionProvider</property>
       <property name="hibernate.proxool.pool_alias">Proxool-DBPool</property>
       <property name="hibernate.proxool.xml">proxool.xml</property>

        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
      <property name="hibernate.show.sql">true</property>
       <property name="hibernate.current_session_context_class">thread</property>
<mapping resource="xxxx.hbm.xml"/>
................................
    </session-factory>

I use proxool connection pool with hibernate,when I restart my web application,Tomcat throw exception. It seem that web server want to find a sessionfactory and it can't find it . Why this exception happen?

Try with:

Code:

<session-factory name="java:hibernate/SessionFactory">

Don't forget to rate.

This line from your logs makes me curious:

Code:

2006-08-19 02:09:03,582 ERROR (StandardManager.java:692) - Exception loading ses
sions from persistent storage
java.io.InvalidObjectException: Could not find a SessionFactory named: null
at org.hibernate.impl.SessionFactoryImpl.readResolve(SessionFactoryImpl.

Are by any chance storing the SessionFactory in an HTTP Session? Tomcat will persist HTTP Session accross restarts and it looks like it's trying to deserialize a Sessionfactory instance.
