Hibernate+Struts

Question

Hi everyone
I've already posted this java programming subforum but they adviced me to post in databases or in struts forums, so I repeat it here:
First of all thanks for reading my post.
I've been looking for it on internet for a week but there are different opinions about it. Is it necessary to develope a plug-in in order to integrate hibernate with struts or is it enough adding the hibernate.cfg.xml and hibernate libraries into the project?? I made the second choice.
The fact is that my hibernate project works correctly, but when I integrate it with struts in order to access the database from the web browser, i get a null pointer exception error just when it tries to create the sessionFactory. I have placed de hibernate.cfg.xml in webapps/projectname/src/hibernate.cfg.xml
Looking around, I've seen that the hibernate.cfg.xml in the hibernate project is
<hibernate-configuration>
<session-factory>
<property name="connection.username">root</property>
<property name="connection.url">
jdbc:mysql://localhost:3306/pymmet
</property>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="connection.password">tilour</property>
<property name="connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="myeclipse.connection.profile">pymmet</property>
<mapping resource="pymmet/Presupuesto.hbm.xml" />
<mapping resource="pymmet/Factura.hbm.xml" />
</session-factory>
</hibernate-configuration>
but in the hibernate.cfg.xml that's been copied into the project in webapps (tomcat), the mapping resources are missing.
Could it be the problem? If it weren�t, anyone knows why is giving me that error?
Thank you very much

I second Duffy's comments on the matter of your screen name. Pick one and stick with it. If you forget your password there's a reminder link.
Your previous question:

Right. Struts and Hibernate have NOTHING to do with one another. One's an MVC web framework and the other is an ORM framework.
Furthermore, nothing about either Struts or Hibernate will cause the hibernate.cfg.xml file to be amended during deployment.
If you've got a different set of contents in your configuration file at the destination from the one you had at the target then:
1. Some other process is amending it during deployment (unlikely)
2. You're not deploying the file you think you're deploying (likely)
3. You're not deploying anything, you just think you are (fairly likely).
