Packaging contracts in JARs

In order to distribute contracts, you can place them into a JAR file. This is a very simple job that can be accomplished in just three steps, which are as follows:

1. Consider an empty JAR file.
2. Create, in JAR, a folder named META-INF.
3. Copy the contracts folder from your application into META-INF.

For example, a JAR file that contains the default, tableGreen, and tableBlue contract folders has the structure shown in the following screenshot:

A complete example that uses this JAR file is named ch11_9.
