Hi Feris,
I am currently working with the HSQLDB for my project.
I had similar problem, which got solved.
1. Make sure your jdbc connection is closed every time.
2. Do not run you application as long as you are looking into the
HSQLDB,
close the DB and then run the application.

Dear All,
I'm using HSQLDB as embedded in-process mode for my web application. I
used
to schedule every 1 minutes to check on the HSQLDB database. I open the
db
when context initialized and close it when context destroyed. But when
the
context reloaded I always get Java.lang.NullPointerException when
trying to
execute SQL statement.
What is wrong ?? It looks like everytime the context is destroyed...
the
hsqldb gets lock.
The snippet code like below :
