Packing Apps with built in JRE...

I have a couple of applications that I am trying to capture that install their own JRE however after creating the MSIX they complain that the JRE can't be found and suggest setting JAVA_HOME.   ---...

Is this resolved now? I also got a package which require (Zulu) Java 1.8 and got the JVM.DLL loading error. Also here i guess the variables are not set, but I can't find the solution to get it working.

There are many problems with this app that will need fixes that are "in progress", however there may be additional unidentified issues.

I can say that if the installer sets a environment variable, then the EnvVarFixup is needed. PsfTooling should automatically detect the need for that fixup if that is the case.

    Hi Tim thanks for your response. I tried using the PsfTooling and it did detect the environment needed, but I was not able to get it in my package. I tried manually which also failed....will try again until I get it working 😉

      The new version of the free PsfTooling (4.14) is now available in the Microsoft Store or TMurgent website. This includes many important fixes to the PSF that I announced earlier today (https://www.tmurgent.com/TmBlog/?p=3309 ).  This version solves a number of launching issues that we have been discussing, including PSF Scripting, and the launching of cmd files directly from the launcher.

       

      Of importance for me to point out: The shell launch of a cmd/bat file by PsfLauncher used to drop out of the container and have no access to package files.  This is due to a change made by Microsoft a couple of years ago in the OS.  I found a way to overcome this in the 2021.09.23 PSF version, so that those shortcuts will work as you'd expect now.

       

      I'll also mention that one of the apps with a "crappy java" I was pointed to was the UVC app.  This is a very old Java version which has additional behaviors that the PSF can't cope with today due to unanticipated OS limitations in the container.  Sorry!

        TIMOTHY_MANGAN Hi, when using the 4.14 toolbox I do get another psflauncher versions then when I download the psflauncher from the github location (https://github.com/TimMangan/MSIX-PackageSupportFramework/blob/develop/ZipRelease-v2021.09.26/ReleasePsf.zip)

        From the toolbox the size is much much larger and seems not to work with me.

        When using the ones from github, the package starts working 😉
