Java sample code to call the load calculation web service for container and truck loads

This sample code shows how to pass the shipment information including the size of the 20FT container and the cargo list from Java pages to the remote CubeMaster server and take the calculation back. The web service calculates the load plan from the shipment information and the load plan is sent to your computer after the calculation finishes. The client take the load plan and shows the calculation to the console of your computer and saves the 3D graphics as GIF picture to a folder at your computer.
