Subject Re: JPA component in a JEE5 environment: EntityManagerFactory from JNDI
Date Mon, 31 Aug 2009 11:51:58 GMT
Hi

That is the same s*** with the J2ee servers and the JNDI lookup. Its
painful when it does not work and you need to setup all kind
of indirections in various deployment descriptors both standard j2ee
related and server specific.

I will try googling and look at WebLogic documentation as its a pure
WebLogic + Spring J2ee lookup thingy.
