Module 1 - Developing a full solution to the lunch ordering problem
By now you have already gotten started by building a simple version of an application, and have dived into the requirements and high-level design of a real solution for our sample problem. With our design in hand, we are now ready to start building out the real thing.
This module assumes you have already done the exercise Quick start: creating a simple app to order some lunch earlier in this tutorial.
If not, you can go back to do that exercise now (this is strongly encouraged).
If you would like to skip this, or want to be sure you are starting with a clean version of the basic application, you also install a pre-built one by using the following steps:
- If you already have an application in your sandbox called com.example.lunchtutorial, you should uninstall it from your workspace (of course, you can use Create Install Package first to keep a snapshot of it before you do this if you like). This is to make sure that you don't have a mix of definitions, because installing an application does not remove any previous definitions.
Download com.example.lunchtutorial-1.0.1-INSTALL.zip. This package includes the work that would normally by done in the orientation.
To download the ZIP file, right-click the URL > Save link as. The ZIP file will get downloaded to the default download location of your web browser. You must use the 7-Zip utility to extract the contents of the ZIP file, and view the install package components. The contents of the install ZIP file cannot be extracted by using the Windows Zip utility or Mac archive utility.
- Use the Install button from the Workspace view to install this application.
- Also download and install the package com.example.util-lib-1.0-SNAPSHOT.zip. This includes some handy additional view components to spruce up views, including a picture viewer. It won't be needed until mid-way through the tutorial but there is no harm in installing it now.
