Subject Re: Connect a bundle to a data base
Date Tue, 20 Mar 2012 12:13:28 GMT
Absolutely. That is what I wanted to say in my last post. The only 
problem with this aproach is that you hardcode the database type in your 
bridge bundle.
( At least if you dont want to mess with the classloader).

As you probably will not have that many database types in one use case 
this is probably ok though.
