Hibernate class loading issue

[nilshan]

Hello..

In my application I am using Hibernate 3 + Spring 3.1 + Jboss AS 7.1.0

The EAR deployment is something like

ECOM.ear

  |

  |-- Message.jar ( EJB Jar )

  |-- Queue.jar ( EJB Jar )

  |-- Console.war ( war )

  |-- lib ( Hibernate 3 jars + other jars )

in my jboss-deployment-structure.xml I have added

<deployment>

    <exclusions>

        <module name="org.hibernate" />

    </exclusions>

</deployment>

I have been facing issue ( stanalone deployment mode ) for above ear deployment:

: java.lang.classcastexception org.hibernate.dialect.mysqldialect cannot be cast to org.hibernate.dialect.dialect

I guess this is class loading issue. How would I stop my ear loading the classes that jboss AS 7 provides.

Please provide suggestion..Thanks.

The above problem is solved by adding custom module for hibernate 3.

     <module name="org.hibernate" slot="3" export="true"/>

I have other question regarding same structure.... 

ECOM.ear

  |

  |-- Message.jar ( EJB Jar )

  |-- Queue.jar ( EJB Jar )

  |-- Console.war ( war )

     |----WEB-INF/LIB...   ( Here, at deployment time the referenced jar are being copied from EAR/LIB .. e.g spring jar)

  |-- lib ( Hibernate 3 jars + other jars )

Here, the Console.war refers to ECOM.war/Lib jar files at compile time for compilation errors.  When I do deploy the EAR, the referenced jar files from EAR Lib is also copiled to Console.war / WEB-INF/lib.  

This creates the class loading issue.

How would I exclude the WAR / LIB at jboss deployment process using jboss-deployment-structure.xml so, that classloading issue can be resolved ?

E.G.

<sub-deployment name="Console.war" >

         <resources>

             <resource-root path="WEB-INF/lib/*" >

                   <filter>

                     <exclude path="/**"/>

                   </filter>

             </resource-root>

        </resources>                  

           <dependencies>           

            <module name="deployment.ECOM.ear.Message.jar" export="true" services="export"/>

            .........

        </dependencies>       

</sub-deployment>

Something like this.....?

Please provide your suggestion or better deployment approach... Thanks in advance.
