Help Needed for PostGreSQL and Java Connector

I have configured Java Connector and iam always getting “XML refers to not existing parent” error. I gave print statement in servlet, thats not printing at all. Seems control is not going to servlet at all. Can anybody help?

Have you configured mapping between the url used in tree.load command and servlet class?

Hi Thanks for the reply. Yes there was a mistake in mapping it works now but only for mysql. Iam having issues with postgresql. Iam not getting data from DB. Always the error is “Error Type: Data Definition”. Description: XML refers to not existing parent. Can you please help. Thanks in advance.

Try to enable server side logs - there must be some error in DB connection or in DB query code. … nd_logging
