Hi all.

I hope you can help be resolve a problem with including mappings from one jar in another project.

I am using Hibernate v2.1.8 for a project consisting of two separate project strctures:
- one containing a framework with a number of classes persisted using hibernate and
- service structure which also persists a number of classes using hibernate and
relies on the mappings in the framework.

I have tried to include the mappings from the framework.jar by using the

tag in the hibernate configuration of the service project. However it throws a NulPointerException inside Configuration.addJar(String) - the problem is cause by getResource("framework.jar") called on the context class loader returning null.

(I have also tried with both relative and full path to framework.jar - but nothing seems to work.)

I know for a fact that framework.jar is in the classpath as other parts of the service project can access classes in the framework.jar without problems.

If I use the following code when configuring the HibernateSessionFactory



it works fine, however specifying the full path to framework.jar is not acceptable :o(

Since addJar(String) uses the classpath resource method to find the file, you need to specify the value relative to framework.jar's location on your classpath. If you're deploying a webapp and you have framework.jar in WEB-INF/classes, for example, you would specify Configuration.addJar("/formula.jar"). Makes sense?

That does not work, if I set my classpath to /home/user/lib/ (so framework.jar is on the classpath) I get a nullpoiinter exception from new Configuration().addJar( "/framework.jar" ) - again because the getContextClassLoader().getResource("/framework.jar") returns null. *sig*
