An HTTP 500 error means that something went wrong on the server and the server could not process the request. Typically you don't get any additional error information and it is frustrating to solve the problem because it could be anything.

But you're lucky, you actually have more information than you would normally get.

According to what you posted, you are encountering a NullPointerExce ption on line 132 of your Dbconnect.java code file.

This means that the connection that you tried to use was not properly instantiated/created/"newed".

Check out that line and make sure that the variable is properly created before you try to use it.
