For the javaagent, classLoadEnhancement=true is the default, which controls whether OpenJPA load-time class enhancement should be available in this JVM execution. Starting in OpenJPA 2.0 - If a javaagent is not provided via the command line and OpenJPA is running on the Sun 1.6 SDK or IBM 1.6 JDK (SR8+), OpenJPA will attempt to dynamically load the runtime Enhancer. This support is provided as an ease of use feature and it is not recommended for use in a production system. Setting the property openjpa.DynamicEnhancementAgent to false will disable this function. When then dynamic enhancer is loaded, the following informational message is logged: [java] jpa.enhancement INFO [main] openjpa.Runtime - OpenJPA dynamically loaded the class enhancer. Any classes that were not enhanced at build time will be enhanced when they are loaded by the JVM. So, is another module (like a deployer, annotation scanner or Tomcat) possibly loading the classes before the OpenJPA GBean is being loaded and having a chance to register the TransformerAgent? > 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. > > 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.

Donald Woods commented on GERONIMO-5553:
In geronimo-transformer, the TransformerWrapper class is commented out and no
longer used, but geronimo-persistence-jpa20 and geronimo-aries-jpa contains its
own implementation of TransformerWrapper, which only calls the transformer if
the provided classloader is an instance of BundleReference? Is that the right
behavior for geronimo-persistence-jpa20 for a WAR case, where it is not a
Bundle? Seems okay for the Aries case...
public byte[] transform(ClassLoader loader, String className, Class
classBeingRedefined, ProtectionDomain protectionDomain, byte[] classfileBuffer)
throws IllegalClassFormatException {
if (loader instanceof BundleReference && ((BundleReference)
loader).getBundle() == bundle) {
try {
return classTransformer.transform(loader, className,
classBeingRedefined, protectionDomain, classfileBuffer);
} catch (IllegalClassFormatException e) {
throw e;
} catch (RuntimeException e) {
return null;

Aries JPA kicks in when a bundle with Meta-Persistence header is deployed. So it's not really about application being deployed as a wab. Either way, however, Aries JPA will not be used when deploying a regular Java EE web application. Second, everything is turned into a bundle during deployment so even a war module should have a classloader that implements the BundleReference interface. But this is probably good place to put a break point to see if transform() is being called. Third, I know that JPA runtime enhancement is working fine in Geronimo for Aries applications at least because the testsuites/aries-testsuites/jpa tests are passing. > 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. > > 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.

Looking back at ARIES-320, you added and them removed code to enable the javaagent support and instead in geronimo-aries-jpa created "GeronimoManagedPersistenceUnitInfoFactory extends ManagedPersistenceUnitInfoFactoryImpl". How did this enable the javaagent for Aries apps??? Guess I'm wondering, if the app is being loaded as a bundle, is OpenJPA being loaded as a bundle? We have tons of places in OpenJPA where we're looking up classloaders, but only one place (broker factory creation) that we try to use the bundle context if available (which was OPENJPA-1491 for Aries.) So, if the OpenJPA transformer uses the bundle context, what is the runtime using and are we seeing two copies of the class, one enhanced and one not? > 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. > > 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.

Debugging the geronimo transformer wrapper, I'm seeing the transformer getting called on the Book class and all other classes of this application, so it looks like the javaagent hook is working correctly. I deployed this application on 2.2 to see what would happen, and it gave a similar (but different) error, which leads me to believe this really can be closed: org.apache.openjpa.persistence.A rgumentException: No metadata was found for type "class org.apache.sample.entiti es.Book".

[jira] Commented: (GERONIMO-5553) Fail to enchance entities on Geronimo
[ https://issues.apache.org/jira/browse/GERONIMO-5553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12905625#action_12905625 ] 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 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. > > 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.
