How to run a java executable file on other computer

Question

I made a small application using Java Swings and then created a jar file of the project using 'clean and build' option in Netbeans. Then, I converted that .jar file in a .exe file using the software 'Launch4j' and it was perfectly running on my laptop. However when I tried running that exe file on other laptop. It displayed the error: Class NewJframe.firstfile couldnot be found. ( I made the database on the other laptop also with MySql Connection).

Please help me clarify why I am getting this error. Also, I would like to know what all are the requirements to run an .exe file on other computer which I made from a .jar file?

Answer 1

I would pretty much expect something like Launch4j to take care of all your packaging requirements; did it give you options to "include all dependencies" that you didn't click "YES" to...?

It sounds like it's packaged your app, but possibly not the Java runtime envt it needs to run your app.

Answer 2

Try giving him the JAR file and see if he can run that. If he can, It's a problem with Launch4j, if he can't it's a problem with Java.

Alternatively try something like Excelsior JET instead.
