B4J Question evolving from Java 8 to openjdk 11

[rbirago]

I have always used standard java environment, using Launch4j to create executable objects. I have seen that in the last year B4j ide has a built-in procedure to create directly exe files and so I have decided to follow this new way. So I have substituted the standard java environment with OpenJdk 11 (mandatory to use the built-in procedure).
Now, when I try to execute the .jar (like I was used) the system replies with this question:

but at the same time executing in release mode the application it starts as usual. So, which is the correct path to launch the .jar?
I have tried to point to jdk-11.0.1\bin\javaw.exe or java.exe and also to the old jdk1.8.0_251\bin\java.exe, but it doesn't execute my .jar
thanks

The forum search is your friend.

Unlike JDK 8 JDK 11 will not run a jar by double clicking it.

Running jars under OpenJDK 11

With Java 8 you could run a jar on a Windows PC by double clicking on it. This does not work with OpenJDK so as I want to be able to quickly run some utility B4J programs easily without packaging them this is what I did. 1) I installed OpenJDK in a convenient place, mine is in 'C:\jdk-11', and...

or you can use a batch file as in post #2 of the link above.

or best is probably the integrated packager

Integrated B4JPackager11 - The simple way to distribute standalone UI apps

B4JPackager11 is a utility written in B4J that uses the underlying Java tools to create a standalone package that doesn't depend on any other software being installed. It works with OpenJDK 11 and OpenJDK 14. Starting from B4J v8.30 it is integrated in the IDE and available under Project - Build...

This is the problem: I have generated the exe by the buit-in ide procedure and this is the log error (using run_debug.bat):

note: launching the app on-the-fly by ide all is ok!

It looks like you haven't read the integrated package tutorial. The answer is in there - Tips and special cases #2.

...of course you are right! now all it works. Really this new method seems to be easier, but has some tricks: the #packager properties, the set of directories I have to pass with the .exe, the dirapp files I have to copy every time in /bin directory...I was used in other rules and so I have to evolve myself. Thank you for the help!
