Hi ranchers

I am creating a small application which I am going to deliver as a jar file. The main class inside that jar file has to execute one .exe file if some condition is satisfied. I have put the exe file also inside the jar. But while running the jar file, it is not executing the .exe file. If I put the .exe file inside the folder from where I am running the jar file then it is working fine. But I cannot deliver as a jar file and a exe file.What can I do now?

By the way, I am using Runtime.getRuntime().exec() method to execute the exe file from the java program. Help me out friends.

You won't get it to execute from within the jar file - you need to extract it into the directory, and run it from there.

If it wasn't clear from the previous post, you might try opening the jar file (that you know must be there, since that's where your app starts), searching for the exe, and writing it out to the local directory. You could also clean-up (delete) the file if you want. The classes you need are contained in standard Java (java.util.zip).
 
It is sorta covered in the JavaRanch Style Guide.
