Thanks Prabhat. That works now. There already is a hsqldb-ds.xml file within the deploy directory which has the same information. Are these two files hsqldb-ds and portal-hsqldb-ds.xml each necessary? Actually, now I have a whole running portal application to deploy. It connects to a posgresql database and it has a mycomp-ds.xml under the deploy directory. I try to run it, and it gives the same error as I stated above. Should I have a portal-posgresql-ds.xml, when when I have a mycomp-ds.xml which has the datasource info to connect to the posgresql database? I wish to be clear about it. Thanks a lot.
