B4J Question [Solved] Java 181 update on Windows 10

[jroriz]

Hi.
After install java 181 update on windows 10, my jar aplication does not work anymore.
After lauch the application, a window pops up and disappears quickly. It seems to be a DOS window, because the background is black.
I installed B4J on the computer, and the program works on the IDE, but the compiled JAR application does not work.
Does anyone help?

open a command window and call the jar from here manually
java -jar yourjar.jar

Thank you.

Ok, now I've created a batch file with java -jar myapp.jar.
The application opens, but the DOS window remains open, and if that window is closed, my application closes.
Is it possible to start the application through a batch file, but without getting the DOS window open?

You dont need batch. Just open cmd and run donmanfred suggestion (navigate to your jar)

It's because the application has to start with windows ...

 

[EnriqueGonzalez]

You open CMD so you can see the exception causing your app to crash. It does not matter if it is a UI application, it will work with CMD

Solved!

JAVAW instead of JAVA.

Javaw starts the application without the console.

The window was the console.
