That's not a missing library. It's a version mismatch. It appears that your JPA api version is incompatible with your Hibernate version.

A quick comparison of javax.persistence.Persistence between Java EE 5 and Java EE 6 plainly shows that the getPersistenceUtil() method was added in 6. If you're stuck with a Java EE 5 server/library, then you'll have to use an appropriate version of Hibernate or whatever Hibernate jar is looking for that method. It seems to be coming out of hibernate-validator.
