Error description
Issue making the openJpa work with WAS 6.1.0.31 + EJB3 feature pack. See the error thrown below: [08/04/11 15:53:37:514 UTC] 00000020 SystemOut O <openjpa-1.0.4-SNAPSHOT-r420667:908274 fatal user error> org.apache.openjpa.persistence.ArgumentException: The type for "test.aaa.bbb" is mapped to custom strategy"test.DecimalWrapperValueHandler", but this strategy cannot beinstantiated. at org.apache.openjpa.jdbc.meta.MappingRepository.mappedStrategy(Ma ppingRepository.java:953) at org.apache.openjpa.jdbc.meta.MappingRepository.defaultStrategy(M appingRepository.java:750) :::::::::::::: Caused by: <openjpa-1.0.4-SNAPSHOT-r420667:908274 fatal user error> org.apache.openjpa.persistence.ArgumentException: The class name "test.DecimalWrapperValueHandler" used in a metadata extension on field"test.aaa.bbb" is not valid. at org.apache.openjpa.meta.JavaTypes.classForName(JavaTypes.java:22 7) at org.apache.openjpa.meta.JavaTypes.classForName(JavaTypes.java:19 4)

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V7.0.0 and V8.0.0 who use an * * OpenJPA * * ValueHandler or FieldStrategy. * **************************************************************** * PROBLEM DESCRIPTION: OpenJPA doesn't find a ValueHandler * * and/or FieldStrategy class with an * * applicable class loader. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a user's JPA entities makes use of (implement) an OpenJPA 'org.apache.openjpa.jdbc.meta.ValueHandler' or 'org.apache.openjpa.jdbc.meta.FieldStrategy', a potential exists for said classes/implementation to not be found by the current classloader. That is, take the following code as an example: package test; @Entity public class TestEntity { @Id private Long id; @Persistent @Strategy("test.MyStringValueHandler") private String testString; ..... package test; public class MyStringValueHandler extends org.apache.openjpa.jdbc.meta.strats.AbstractValueHandler { ..... When OpenJPA attempts to load the 'MyStringValueHandler' class (the class listed in the @Strategy annotation), it may not be able to load the class depending on the classloader in use. In this case OpenJPA is attempting to load the class with the wrong classloader. Thus the following exception results: org.apache.openjpa.persistence.ArgumentException: The type for "test.TestEntity.testString" is mapped to custom strategy "test.MyStringValueHandler", but this strategy cannot beinstantiated.
Problem conclusion
With this fix, code has been added to ensure that OpenJPA uses the correct classloader when it attempts to load a class which has implemented a 'ValueHandler' or 'FieldStrategy' interface. The fix for this APAR is currently targeted for inclusion in Service Levels (Fix Packs) 7.0.0.21 and 8.0.0.2 of WebSphere Application Server versions 7.0.0 and 8.0.0.
