Hello World Recap
It's important to recap what we have done. We created a common Java library called model.jar. This model.jar file is used by a Web application and a standalone executable Java application in an executable JAR file. We created an applet that can communicate with the Web application we will create in Chapter 6. Once the applet loads into the browser, the applet communicates over HTTP to the Web application's HelloWorldServlet, which is covered in depth in Chapter 6.In Chapter 4 we set up the GreetingFactory so that it talks to an enterprise session bean that in turn talks to an enterprise entity bean. The Web application buildfile is set up so that with the addition of a property file, it can talk to either the enterprise beans or to the local implementation in the model library.
