Re: ProjectStruture

Thanks Jens... perfect. Exactly what I was after (before I disappeared down a dead-end of rpc calls and tons of re-writing, which I'd probably give up on).

Loads to look in to, and get going on.  Thank you. I'll see how far I get and post any questions I have.  Hopefully my only remaining concern is the file upload and download functionality.

Thanks again, much appreciated.

Regards, Sam

GWT-RPC is just one convenient way to communicate with a server using GWT. However GWT-RPC uses its own serialization format that is based on JSON. While convenient to use GWT-RPC also has some pain points that are often discovered later.

If you just want to make a POST / GET to an URL and transfer some serialized data (JSON, XML, custom) you can use GWT's RequestBuilder class (which is actually used internally by GWT-RPC as well). In order to get your XML going you can use GWT's XML API http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsXML.html or use a library that maps from Java POJOs to/from XML. As example of such a library take a look at https://github.com/hpehl/piriti

The above should allow you to not rewrite all the server side code.
