B4J Question Publishing To Windows Store Problems

[keirS]

I tried to use the store packager tool to publish to the windows store but the builder use does not support JPOI. So I built the package manually using the B4JPackerger11 and MS Desktop Packager Tool. I can create the APPX package OK and it will install but it doesn't run.

Running process monitor it appears that Java is run but it is looking in the wrong place for the release_java_modules.txt

I think it maybe running Java from the wrong place as well since it is showing access to:

C:\ProgramData\Oracle\Java\javapath is the entry in my command line path.

Solving my own problem. I changed the C# code in B4JPackeger11 to:

File.WriteString(TempFolder, "runner.cs", $"
  
using System;
using System.Diagnostics;
namespace B4JRunner
{
    class Program
    {
        static void Main(string[] args)
        {
              
            string StartDir = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);
            Process p = new Process();  
            p.StartInfo.FileName = "javaw.exe";
            if (StartDir.Length > 0)
            {
                p.StartInfo.WorkingDirectory = StartDir + @"\bin";
            }
            else
            {
                p.StartInfo.WorkingDirectory = @"bin";
            }
          
            p.StartInfo.Arguments = "@release_java_modules.txt -m ${TargetModule}/${PackageName}.main";
            p.Start();
        }
    }
}"$)

According to this Stack Overflow post that's the best way to get the start location for APPX installation. This returns an empty string when run straight from windows so I just kept the current WorkingDirectory setting if StartDir is zero length. There is probably a better way of doing it but it works.
