When starting JBoss (3.2.3 on Solaris 2.8), we recieve the following errors:

--------------------------------------------------------------------------
org.jboss.resource.JBossResourceException: Could not create connection; - nested

I have removed all the files from the {jboss}/data/hypersonic directory, the localDB.data, .script, and .properties file are recreated however this error persists. Why is it trying to access the localDB.backup ? We had one in the directory however the problem persists. I removed it, did a touch localDB.backup and still the problem exists. Has anyone had this problem or know how to fix it ? Help is greatly appreciated.
