I have solved my initial problem, probably by copying hsqldb.jar to $GLASSFISH_HOME\domains\domain1\lib and restarting the server several times.
I now have the following error when I try to ping:
"Connection object cannot be null"
I really don't know where this error comes from.
If it comes from the properties, this is the additional properties i set:
User: auser
Password : apassword
Database: hsqldb:hsql://localhost/contact
(these are the only important properties I found in the jdbcDataSource class).
I really don't understand what'd happening, any help would be appreciate.
Thank you in advance.
