Hi all,
Pleas help.
I am using hibernate 3.1.3. and integrated with struts application.
MySql
Weblogic 8.1
I am using Weblogic connection(from JNDI look up).

I deployed it as a war file in weblogic 8.1.But when I access this application after a very logn time(next day) it fails at JDBC part and gives the error given at the end.
But when i redeploy this in weblogic it is working fine.

MY config file as follows:

<hibernate-configuration>
<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping resource="/dao/hibernate/Tutorial.hbm.xml"/>
</session-factory>
</hibernate-configuration>

Error :
