Sessions.xml is not found when debugging multiproject configuration

Question

I have a TOPLink project and it works fine when I am debugging it. But when I am debugging a servlet located in another project and uses my TOPLink project, the sessions.xml file is not found even if I pass it as an absolute path to the xmlloader. Why?
I use the following construction:
xmlloader = XMLSessionConfigLoader( absolute_path_of_sessions_xml );
session = sessionmanager.getSession( xmlloader, name_of_my_session, class_loader );
I tried to pas this.getClass().getClassLoader and
Thread.currentThread.getContextClassLoade as class_loader, but without success. It's unbelievable. What can be the problem?

Answer 1

How are you packaging you application?
TopLink mapped classes and configuration files can be packaged directly in the WAR file under WEB-INF/classes.
Alternatively you can package your model and configuration files in a separate JAR file in your EAR separate from the WAR file where the web application (your servlet) is located. In this case you will need to configure the WAR file to explicitly have access to the contents of the JAR file.
There is also the option of accessing your persistence through a session bean facade using an EJB JAR file but this would not involve your servlet directly accessing the TopLink configuration.
Can you described how you are packaging your application and we can give some more pointed guidance on classpath location of your TopLink configuration files.
