Derby Embedded Database: errors in connection code

I've coded connection code for an embedded db in NetBeans. Something is wrong with my return connection. Any ideas? I added color=red to the code that is generating the errors, but it is appearing in code. See lines 21, 39, 70, 100, 122, and 144. When trying to compile, I'm getting an error which reads, "cannot find symbol
symbol: variable connection
location: class ProductDB"

This is my first time working with Derby.
