Eclipse generates the basic procedure and example of SWING application
First, SWING project
1. Create a new project
Project -> Java-> Java project, then click "Next" to name "SwingTest" for the project, click "Finish".
2, create a new package
On the project established, click Right click, create a new-> package, name "SRC", click "Finish".
3, create a new class
On the package you just created, click Right click, create a new-> class, named "Buttondemo", click "Finish".

4. Run new class
Run -> Run to -> 2.java app
If everything is normal, OK, you can pack it.
5, play jar package
Right click on the project -> Export -> JAR file, the next step, then select the storage path, as shown in Figure 1. Then continue the next step to select the class of the program entry point. Figure 2. Then complete it. JAR package is already good.
figure 1
figure 2
Second, configure Java Web Start
1. Under the Tomcat's WebApps folder, create a folder, name "SwingTest", then put our JAR package, put it in.
2, at the same time, built two files, one is index.html, one is index.jnlp
The content is as follows:
INDEX.HTML
Index.jnlp
