It looks like you're trying to make a direct connection to your IBM DB2 database, which App Engine's sandbox doesn't permit:
http://code.google.com/appengine/docs/java/runtime.html#The_Sandbox If you want to use an external database, you will have to place a web service in front of it and use App Engine's URL Fetch library. Or you can use App Engine's datastore directly which is preferred. There are JDO and JPA interfaces for code portability: http://code.google.com/appengine/docs/java/datastore/ - Jason On Sat, Sep 12, 2009 at 9:08 AM, Ravi Mandliya <[email protected]> wrote: > > Hello everyone I just uploaded my first application, its running, and > seems to be working fine, > but there is a problem, I get the following error when onblur() on the > textbox is activated, I have applied ajax which fetches the data from > Database(IBM DB2).
