Does this depend on other jars? I am trying to run the OpenJPA in J2EE Applcation Client on Rational Software Architect 7 using DB2 as database. Thanks for help. -- View this message in context: http://www.nabble.com/NoClassDefFoundError%3A-serp.util.Strings-tf3678480.html#a 10279501 Sent from the open-jpa-dev mailing list archive at Nabble.com.
