Hi,
I also posted this issue over the Spring forum:
http://forum.springframework.org/showthread.php?p=97510
Basically, when I used Spring and Glassfish's Toplink and packaged the webapp as a .war archive I would get a ClassNotFoundException. Everything worked fine if I re-pakaged it as .ear archive.
If I replaced Toplink with Hibernate JPA implementation, my Spring webapp deployed as a .war archive didn't have any problem.
I want to use Toplink since it came with Glassfish and don't want to load my webapp with Hibernate libs.
I'm not sure if this is a Spring or Glassfish issue, but I have seen many users with the same problem.
