JBoss,Hibernate and Caching Issue

[manjith27]

Hi,

I am using Hibernate 3.1 and JBoss 4.0.2.
We have integrated caching, clustering in Jboss.
Now, I keep the instance of SessionFactory in our predefined Cache which implements JBoss supported Caching Framework.
I have written a test JSP which calls the SessionFactory instance from the caching and create a session object from it and does the CRUD functions.
The problem is for the 1st request the SessionFactory object which I placed in the Cache is null. For the 2nd and consecutive requests the SessionFactory object retrieved from the Cache and performs the CRUD functionality properly.

But when I run the same code in the standalone application with a test program, the Test executes without any issues.

I have enable the use_query_cahe to true in hibernate-cfg.xml.
My hibernate-cfg.xml is: -

<property name="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</property>
 <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
 <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:test</property>
 <property name="hibernate.connection.username">test</property>
 <property name="hibernate.connection.password">test</property>
 <property name="hibernate.cache.use_query_cache">true</property>

And my treecache-service.xml is:

<server>

 <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/>

 <mbean code="org.jboss.cache.TreeCache"
 name="jboss.cache:service=TreeCache">

Please, let me know If I need to add any other configuraton over here.

Thanks In Advace For the solution.
