Re: Self referencing Entity causes id already assigned value on entity save

Hi mxc, could you post the exception stacktrace and the code snippet causing the error? the one where you add the entity and the parent and persist them. Simone mxc wrote: Hi all, I have a simple node entity pretty much as follows - @Id

Re: Eclipse - javaagent enhancement

Hi Kevin, After debugging, I discovered that I need to have a META-INF/persistence.xml file on my classpath for this to work otherwise no ClassFileTransformer is installed and hence enhancing does not work. It may be worth to explicitly state that out-of-the-box the javaagent requires a META-INF

Re: random insertion order for inherited classes

Heather, What release/revision of OpenJPA are you using? There was a semi-recent situation with the ordering of inserts in our statement batching support that you may be running into. OPENJPA-817 ( https://issues.apache.org/jira/browse/OPENJPA-817) documents the problem I am thinking of. Besides

random insertion order for inherited classes

Hi, I am experiencing some weird behavior regarding the insertion order for inherited classes. I am using the join table strategy and some of the time it inserts the superclass first, while other times it inserts the subclass first (thus resulting in an exception). It's completely random, with

Re: Eclipse - javaagent enhancement

Adam, Provided you have your pu's defined separately, the agent allows you to specify a particular persistence unit for enhancement. Example: -javaagent:C:/eclipse.workspaces/3.2.2/openjpa-1.2.0/openjpa-all/target/openjpa-1.2.0.jar=pu=OpenJPAPU -Jeremy On Fri, Jan 30, 2009 at 11:05 AM, Adam Ha

Re: Eclipse - javaagent enhancement

Hi Kevin, whilst on the subject, I'm using this in Eclipse too but there is one thing that it appears cannot be done. One of the projects I work on is a framework that is designed to be used with any JPA provider, and the testing runs against OpenJPA as well as Hibernate and Toplink Essentia

Hi Gianny, I use this all the time. On my Run configuration for the application that I am running I will put something like the following as a JVM argument... -javaagent:C:/eclipse.workspaces/3.2.2/openjpa-1.2.0/openjpa-all/target/openjpa-1.2.0.jar This should kick in the PCEnhancerAgent for the

Eclipse - javaagent enhancement

Hi, I am unable to get javaagent based enhancement work within Eclipse. Based on a cursory review of PCEnhancerAgent, I can see that no ClassFileTransformer is installed when List anchors = Configurations. getFullyQualifiedAnchorsInPropertiesLocation(opts); returns an em
