If it works when you run it from the IDE and fails when you double click on it then the problem is with the default Java JRE.

Make sure that jar files are associated with the latest version of Java installed on your computer.

You can also run Java -jar tt.jar from the command line and see the error message.

It's strange
I runned the command : java -jar tt.jar => It works
after i runned tt.jar directly => it works

thank you for your help

Hi, I checked your application and I found the error to be in a port not being released.
If you first run the application outside the IDE, using the default JRE, it will work, but when you close the application, the actual java process is still opened, so when you relaunch the application, it will fail when trying to bind the port.
Probably it works in the IDE because when you stop the execution of the application it is killing the JRE process.
Ensuring to release any opened port when the application process quits should solve the problem.
