[SOLVED] Double-clicking .jar files?

[StokedOnMe]

Hey guys, I've been programming for a while, but I never made executables... just ran it from the compiler. Now, however, I really want to have an icon for one of my programs that would be conveniently located and clickable. So, I made a jar file, both in Eclipse and BlueJ. When I run this file in command line, it works fine (with "java -jar ..."). In case of Eclipse, this worked with both "jar" and "Executable jar" options. However, when I double click the icon, nothing happens. First I was getting "can't find main class" error, but that was an easy fix with the manifest file. But now, nothing seems to happen at all. Could this be because the program is supposed to run in the command line or whatever the compiler offers and there is nothing to force the computer to open one of those windows? Please help, this is very frustrating )))

With Windows make sure you are using java.exe and not javaw.exe to run your jar file. The latter does not display a console window.

Alternatively put the command that you know runs the program properly inside a batch file.

Ok, so I went to properties of the jar file and made it open with java.exe instead of javaw.exe. However, all that achieved is that now the DOS window flashes for a split second and disappears :/

How would I put the command inside the file?

The following works for me (hw.jar just prints hello world to the console).

@echo OFF
java -jar g:\hw.jar
pause

Wow! Thanks a lot! That was easy ))) Didn't even need the "pause" line really... for the purposes of this program at least.
Thanks again.
