Hello,
Presently I have a working persistence.xml file - I can deploy my project and it runs correctly, storing entities in the database using container managed transactions. Unfortunately when I run "generate tables from entities" using Dali I get the exception listed below. Changing transaction-type to resource_local to bypass the app server works fine, but container managed doesn't seem to work. From what the guys in the Dali forum tell me, the table create is delegated to eclipselink. Any ideas what's going wrong?

Hello MJ,

From the bit thats there, the exception is coming from trying to look up weblogic.transaction.TransactionManager from within a new InitialContext, which throws the NoInitialContextException, which is odd if it is occuring within the server. Can you provide the full exception stack trace?

Best Regards,
Chris
