The program I write in Eclipse runs on console purely. I hope to export it to a jar file then use launch4j make it an executable .exe file. The program should desirably be opened in cmd or terminal on Mac once clicked. But it seems I can't open it with cmd and unless I used swing or awt, nothing to show when I clicked either jar file or exe file. So what is the problem and how should I do to make it runnable on cmd! PS:I dont want to type any command line, just click the jar file or exe file and it started to run on cmd or terminal!

You would possibly try script files for this task:
windows: run.bat
java -jar your.jar mac: run.sh
#!/bin/bash java -jar your.jar 1 Comment

Thank you it works on Windows now. But what if I converted it to an exe file, how should I run?
launch4j could work on windows/osx/linux, but I think you need a mac to build the executable file. And the jar file itself can be run when double-clicked, if you specify the Main Class in META-INF/MANIFEST.MF file, like this:
Main-Class: com.xxx.xxx.YourClass After this, the jar file could be double-clicked to run.

When you export jar file from Eclipse, you can specify the Main Class, so you need not edit the manifest file manually.
This Answer shows the use of Jar Bundler to convert jar to executable native Mac OS X .app executables
I think you can give it a try. Enjoy!
Edit
Jar2Exe seems promising to convert jar file to executable for Windows and Linux Platform.
You can try them and let me know too if that work for you.
