Donald Woods commented on GERONIMO-5553: ---------------------------------------- Reply to the 8/30 questions about enhancer, which dup my 8/27 comments.... When a list of classes is handed to the javaagent, then it will only enhance those classes, but when no class list is given it will discover all classes to enhance. When the 1.6 JVM's Attach API is used (new in OpenJPA 2.0) to dynamically load the OpenJPA enhancer agent, then the class list is used AND any other classes to enhance are discovered unless <exclude-unlisted-classes> is specified in the PU. So, I'll opened OPENJPA-1780 to request that the javaagent behave the same as the dynamic loader.... > Fail to enchance entities on Geronimo > ------------------------------------- > > Key: GERONIMO-5553 > URL: https://issues.apache.org/jira/browse/GERONIMO-5553 > Project: Geronimo > Issue Type: Bug > Security Level: public(Regular issues) > Components: persistence > Affects Versions: 3.0 > Environment: OS:win xp > Geronimo :3.0 20100824 build > Reporter: Lu Jiang > Assignee: Rick McGuire > Fix For: 3.0 > > Attachments: booknew.war > > > I tried to deploy a simple jpa sample on geronimo.But when persist data into > database. > Following exception will occur. > <openjpa-2.0.0-r422266:935683 nonfatal user error> > org.apache.openjpa.persistence.ArgumentException: Attempt to cast instance > "org.apache.sample.entities.b...@97781f" to PersistenceCapable failed. > Ensure that it has been enhanced. > FailedObject: org.apache.sample.entities.b...@97781f -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
