hello,
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. 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?
This is how my hsqldb-ds looks like.
