The library which uses hibernate, contains a package(ejb3-
persistence.jar)
which also uses the class javax.persistence.spi.PersistenceProvider,
the same as in javaee-api-5.0-1.jar package.
The ClassCastException is definitely caused by having two copies of
the javax.persistence APIs in your system (one in the common
classloader provided by us and the one in your webapp). You'll
definitely want to get rid of the jar in your webapp that contains the
javax.persistence API. Assuming that jar only contains javax.*
classes, everything should run fine without it.
