This is a basic implementation of a service that provides retrieval access to the UPC web site. Its was coded to verify basic  proof-of-concept for development of another application and was not intended to provide be anything more than basic functionality in the retrieval  of UPC data from the web site.

There are several places where simple code was left in place rather than using more advanced Java features/methods to allow for easier  understanding of junior developers. Not much time spent refactoring or cleaning up the code. It is provided as a starting point only.

It contains a Factory service that returns a service object configured using the (see below) file found in the class path of  the executed code. The UpcQueryService can respond with an implementation of the UpcResponse and supporting interfaces or with an InputStream  allowing direct access to the response from the from the web site.

JSR 353 is the Java API for JSON is currently under development ( &  The several Java JSON implementations seemed to be more than I was wanting/needing so I wrote a basic parser to provide JSON parsing capability  needed. Its not perfect but is a good basic start.
