hsqldb-ds configuration for server-mode!?
mussie Jan 8, 2008 8:56 AMhello forum,
I'm trying to build a database aplication with jboss and could not make my
data persistent. I allready changed the persistence from create-drop to update in the seam booking example.
So here is my question:
is it correct that I have to change the hsqldb into server mode to make the
data persistent?
I tried to do so by changing the hsqldb-ds.xml in my deploy directory. But when I start my hsql database manager it is still in in-memory type only the URL changed to jdbc:hsqldb:hsql://127.0.0.1:1701.
Does anyone know why my database engine doesn't convert to server based persistence?
This is how my hsqldb-ds looks like.
