Hi
Am I missing something (or just lazy) - but I have written a B4j App and it works great when run under the IDE. However, I am unable to run it on a PC.

I have used the IDE to Build a stand alone package and when I double click on the appname.jar windows asks what file do I want to open it with.

NOTE: I did look this up on the forum but the suggested solutions appear somewhat complex, is that really what you have to do get the App to run?

Kind regards
Dave

You should get an exe file.

aeric is correct. You should get the following folders after the packager is done. My app uses a sqlite database so I had to manually add the
Files folder. Click on the exe file and it should run.

Hi thank you quick response

Firstly, you are correct B4j will create a <appname>.exe file if you wait to let it complete. My machine is doing updates ,so it's slow and there is a gap (several seconds) between producing the <appname>.jar file and the .exe file - My fault for being too impatient.

Also in my case the .exe is written to <projectFile>\B4j\Objects\temp\build and not as expect in the <projectsFile>\B4j\Objects.

Thanks all for your help.
