As described here, I want to update the user's database by means of catching the exception that occurs when the entity classes don't match. I understand that I could add a catch statement to every db-interface method, but that's error-prone*.

I have a JAX-RS webservice (Jersey) that is a CRUD interface for JPA (EclipseLink) entities.

I have a few domain model classes in my web app that have a hierarchical relationship to themselves. An example of one is the hierarchical category structure used to classify users postings.

It generates MyISAM tables by default. I don't want to have to get it to generate a DDL script and then edit that if I can avoid it. I would also like to avoid changing the default table type of my MySQL installation unless I can do that for online one database. Any ideas? ...

1.- I'm working Glassfish 2.1 with EcipseLink 2.0.0, so really using JPA 1.0 specification, and I have a stateless EJB that finds entities among other things. As far as i know JPA 1.0 defines a L1 cache that works at Persistence Context level (transaction level for stateless EJBs) but I can't figure out why the next code prints "Not same...

For me this is a problem because I have a MySQL trigger that fires before a record is deleted. Any ideas on how to get around this problem? Thanks R...
