I've spent a lot of hours trying to replace JDBC with JPA + TOPLINK and I've got many problems and many references to the same code samples, to the same Toplink flaws:
- Toplink jars must be packaged in the war(if a web application) or jar because if Toplink has been initialized, it doesn't reinitialize and desn't find the persistence.xml
- you cannot use two persistence units because when you try to open the second, Toplinks finds itself initialized and it doesn't find the second p.u. And this happens also in a standard JavaSE app
I'm running the latest versions of Netbeans6.1, Glassfishv2ur2 and bundled libraries.
I would like to get a working project of such environment. I use Oracle 10 as DB, but I have also mySql and msSql.
Thanks
