I am using a Hypersonic sqldb. I get this error in Windows XP but not in Windows 2000. What is the workaround for this?

javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query
Caused by: java.sql.SQLException: Table not found in statement [select license0_.id as id69_, license0_.date as date69_, license0_.key as key69_, license0_.expirationDate as expirati4_69_ from License license0_]
