简单的可以用如hello world 我实验过，可以我在将JMFStudio生成.exe时却没有成功，让我report bug
用JET时你的JDK必须是1.3.0 OR 1.3.02我不知道在那里下载!我用的是JDK1.3，但JBUILDER5中的JDK是1.3.02
当然是在sun下载。真是废话^^
Make a JAR executable In the manifest file of a JAR, it is possible to specify the class to be used when the JVM is lauched with the JAR as parameter. The class must have a main(). Try with this simple class import java.awt.*; import java.awt.event.*;public class MyClass { public static void main(String[] args) { Frame f = new Frame(); f.addWindowListener (new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit(0); } } ); f.add(new Label("Hello world")); f.setSize(200,200); f.setVisible(true); } } Then create this manifest file (manifest.mft) with any text editor. Manifest-Version: 1.0 Main-Class: MyClass Classpath: .\MyJar.jar
Next, you include the manifest file in the JAR (MyJar.jar) with the MyClass class. jar cvfm MyJar.jar manifest.mft MyClass.class
Then you are able to start the MyClass.class by double-clicking on the MyJar.jar file (if the JRE is correctly installed) or by typing java -jar MyJar.jar
On NT, you can also make JARs run from the command-line by setting the PATHEXT environment variable, for example set PATHEXT=.EXE;.BAT;.CMD;.JAR Then if you have the jar file MyJar.jar accessible via the PATH environment variable, typing "MyJar" on the DOS command line will invoke "java -jar MyJar.jar" .
