How are you trying to run it on the other system? What error are you seeing?

You probably need to set up you CLASSPATH environment variable so that the required libraries are there for Java to find.

By default Netbeans copies all dependent libraries into a lib directory under the dist directory where it places your jar file. The MANIFEST file it creates tells it to look for dependent jar files in a lib directory under the directory you run it from. Adding the lib file to your jar should work, or creating a lib directory under where you run the jar from with all the required jar files in it, will also work.

I have been using the last option for my Selenium programs, because adding the lib directory to every jar file just means I have the same files copied into every Selenium test program I write.

I took the dist folder as it is containing the jar file and the lib folder.
I did not receive any kind of errors but the button that works well in my system stop working in other systems.

specifically this button using a class I wrote by my self.
other buttons working well (cancel --> close the window and ends the execution -browse--> navigates the files and folders)

I am going to assume that you see the jar file for your class in the lib subdirectory. But check to see if the jar files in the lib subdirectory for that class are also in there, in case it has some dependencies that did not get copied into the lib directory for your project.

The other possibility that I can think of would be that this other system might not have some library installed on it that you have on your development system.

But all those cases would generate an exception saying that a class couldn't be found. If you are not seeing that error then something else is going on, in which case you will probably have to do some debugging on the system where it is failing to run properly.
