Since I could not find out how to buid a crud application with certain tables of a database, I tried to create another instance of the hsql database. In the hsql documentation Table4.1 http://hsqldb.org/doc/guide/ch04.html#N108EC it says that if you're using protocoll hsql and running HSQLDB in server mode
The database to connect to is specified by an alias. This alias is a lowercase string defined in the server.properties file to refer to an actual database on the file system of the server or a transient, in-memory database on the server.
So I'm wondering where to find that file in my jboss-4.2.1.GA there is no such file. Where can I define these settings? In my jboss-4.2.1.GA\server\default\deploy\hsqldb-ds.xml?
