launch4j exe has nothing to say for itself, anyone got a suggestion?

Running on Linux, I've used launch4j to开发者_C百科 package an exe.

I copy the exe into my Windows 7 VM, and run it.

And nothing happens.

I run it with --l4j-debug, and nothing still happens (at least, if there's a log file, I cannot find it).

Is there some diagnostic technology that I'm missing here?


Create a console version of your EXE (in the "Header" tab, change "Header type" from "GUI" to "Console") and run that from a CMD prompt.

Most likely you will see an exception message in the console, and that will explain why your app is failing to start.


The .jar file needs to be an executable JAR file. Make sure it is and try creating the .exe file with the executable jar file. This should solve it!
