Hello Dave,
Thank you for posting a detailed reply. After going through most of the documentation on shortening w/s path and acceptable keys for GAE, I created another Google project in d:\installs\activiti_gwtws and configured it for GAE.
This time I just created an mvc scaffolding using customer, product and employee table from db derby and also enables sessions in appengine-web.xml. Now the datanucleus enhancer error dissapeared but this time while trying to deploy to GAE, it gave the following error
Unable to update app: Error posting to URL: https://appengine.google.com/api/appversion/cloneblobs?app_id=galaxyshastra&version=1&
500 Internal Server Error
<html><head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">

<body text=#000000 bgcolor=#ffffff>
<h1>Error: Server Error</h1>
<h2>The server encountered an error and could not complete your request.<p>If the problem persists, please <A HREF="http://code.google.com/appengine/community.html">report</A> your problem and mention this error message and the query that caused it.</h2>
<h2></h2>
</body></html>
Is this because of the previous deployment?
Thank you,
