    Is there any configuration needed to setup?

    Thanks

    You do need to follow the installation instructions when you upgrade, without skipping steps. If you just randomly copy some files you think might be sufficient, you're going to have problems.

    As far as this particular problem, you probably don't even use HSQLDB, right? That's just an embedded DB we ship with the SDK to allow full-stack samples without having to configure a separate DB. So this kind of looks like you somehow overwrote your actual database config (usually in server.properties) with something from the SDK, and that you also have older versions of sample DBs hanging around in your project.

        Hi,

        Thanks for your update. I tried to remove the old configuration of HSQLDB and finally, it worked.
