如何使Java应用程序独立？

Question

I have to burn a Java application on a CD. This application have to run on every Windows PC wihtout any installation (also JRE shouldn't be installed) before.

Answer 1

I guess you could copy the JRE from your programs folder onto the CD too. Then, add a batch script to use your "local" JRE to start your app. That should be enough, but I don't know if this works with all versions of windows.

Answer 2

You'd have to bundle jre on disk and create startup scripts. If you are not satisfied with simple batch / shell startup scripts you can use something like JLauncher to create "real" executable.

Answer 3

JSmooth can do the trick with bundling JRE or prompting install Java, and it is free . You can also set properties for JVM

Answer 4

The easiest way would be to include an unpacked Java installation on the CD and use it to run the application.

There are AFAIK only 2 "Java to exe" compilers still on the market, one of which (Excelsior JET) is quite expensive, and the other (GCJ) doesn't work on Programs that use AWT or Swing.

Answer 5

Here's one way... Bundle Java (the JRE) and Launch a Java App with 7zip SFX! ... (Convert Java Apps to an Executable, sort of)

Answer 6

只需将jre刻录到cd上，然后在批处理脚本中启动应用程序，该脚本将CLASSPATH和JAVA_HOME变量设置为指向jre。
