I am facing problem with session the Error Message Is :

org.hibernate.SessionException: Error! Please, check your JDBC/JDNI Configurations and Database Server avaliability.
Could not open or put a Hibernate Session in ValueStack: Could not parse mapping document from resource .

The code is : I have a hibernate Configuaration file and struts.xml file....
hibernate configuaration is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

<mapping class="com.mss.domain.MsTpMain" package="com.mss.domain"/>
<mapping resource="hibernate.hbm.xml"/>
</session-factory>
</hibernate-configuration>

struts.Xml is:

<!DOCTYPE struts PUBLIC

"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<package name="default" extends="hibernate-default">

</action>
<action name="listUser" method="list" class="com.mss.web.UserAction">

</action>
<action name="addMsTp" method="addMsTpMain" class="com.mss.web.MsTpAction">

</action>

</package>
</struts>

i properly added every thing still i am getting problems..

Your hibernate configuration references a mapping file hibernate.hbm.xml.
Is this correct and if yes, is this file available/correct?

By the way: We're using the jTDS JDBC driver (http://jtds.sourceforge.net/) instead of the original Microsoft SQL Server JDBC driver as we've experienced several severe bugs and performance issues with the original one.
