> The basic problem is this: I'm attempting to specify some entity listeners
> in my orm.xml , but I continue to get the following TRACE message:
> 322664 my persistence unit TRACE [main] openjpa.MetaData - OpenJPA does
> not currently support XML element "pre-persist". Ignoring.
> The following discussion is from the openjpa-dev mailing list...
> ------------------------------------------------------------
> Marc,
> Thanks for the background on the earlier drafts of the JPA spec. That helps
> explain some of the processing that I see. I also now see that elements
> tagged as MetaDataTags have corresponding annotation support associated with
> them. So, it looks like I just need to provide similar callback processing
> for the pre-* and post-* methods at the "system" level as exist at the
> "class" levels. Thanks for your insights.
