Name and version of the database you are using: Sybase Anywhere 6

When I create a session factory from within eclipse 3.1 I get the exception above and while my tables are displayed under the database branch, almost all of the tables have no column metadata.
Any clues appreciated

What JDBC driver and version etc?

JDBC meta data comes from the JDBC driver so this is the first place to look.
