The "url" variable is null, which is what the error message says.
That's because nothing ever assigns it a value. And that's because the only code which might assign it a value, the code in your init() method, is never called.

I didn't spot the spelling mistake, changed it now, it made no differene to the result though.
I thought i was assigning the string url the property of jbdc.url, and then in TestDB i am calling the getConnection() method which uses the url in it. Or am i missing something?
