Re: [eclipselink-users] eclipselink doesn't find my persistence.xml

[Tom Ware <tom.ware@xxxxxxxxxx>]

Do you see this problem when running a simple JPA program, or just when trying 
to generate a cannonical model?

How is your application configured?
- JavaSE? Jave EE(which server)?
- Where is your persistence unit jar/directory?
- Where is your persistence.xml?
- What does your persistence.xml look like?
- Are all those things on your classpath?
- How are you getting the EntityManagerFactory/EntityManager?
