hsqldb to mysql migtration issues

[David Senter]

I'm having issues migrating an hsqldb to mysql using the migration toolkit. There are a few sites I've consulted for the correct way to do this:

http://wiki.alfresco.com/wiki/Migrating_from_HSQL
http://confluence.atlassian.com/display/DOC/Migrating+from+HSQLDB+to+MySQL

In the connection string for the source database I've put
jdbc.hsqldb:file:C:\Program Files\<path to db>\<database name no extenstion>
and
jdbc.hsqldb:file:C:\Program Files\<path to db>\

I keep getting the same error when connecting to servers:

Connecting to source database and retrieve schemata names.
The list of schema names could not be retrieved (error: 0).
ReverseEngineeringGeneric.getSchemata :Bad version number in .class file

I can't figure out whats causing this. Any help is appreciated. Thanks!
