I used the reference guide to configure mysql as the portal database and also removed the portal-hsqldb-ds.xml file. Checking in the MySQL DB the tables have been created. On trying to access the Portal URL it throws a 'null pointer exception' -- any hints on where I should look at? The Portal is running perfectly with the HSQLDB.
