Testing against multiple JPA implementations

[Marc Prud'hommeaux <mp...@apache.org>]

All-

I recently needed to test out the behavior of other JPA  
implementations for a certain feature, and was annoyed at how long it  
took to download and set up all the various dependencies and  
configuration properties for Hibernate and TopLink, so I went ahead  
and created a template project that will automatically download and  
configure OpenJPA, TopLink, and Hibernate, and run a specific class  
for each of them.

In case anyone else is ever interested in doing this, I've put the  
template up at:

   http://people.apache.org/~mprudhom/interjpa.zip

All you need to do is unzip it, cd to "interjpa", and run "ant". All  
of the logic is in the "build.xml" file, which uses the Maven ant  
tasks to download the dependencies for each of the implementations.

Jacek-

That's a very nice-looking article! It's a pity I don't read Polish.

If you were looking for another place to publish it, one good place  
might be on the jave.net JEE wiki: http://wiki.java.net/bin/view/

Hi Marc,

I've been doing the same with m2 and created pom.xml for OpenJPA,
TopLink and Hibernate with Apache Derby and PostgreSQL. I described it
in my article "Nauka Java Persistence z Apache Maven 2 i dostawcami
JPA: OpenJPA, Hibernate i TopLink" [1]. It's in Polish, but you may
find some useful snippets there. Some steps are no longer necessary
(e.g. Hibernate jars are in the m2 central repo) and the project has
since been updated.

I was wondering whether there'd be some interest in describing it in
more detail, but didn't know where to publish it. Any hints? It's
saved me plenty of time while digging into JPA details.
