B4J Question How to build ui-app with B4JPackager11 ?

[jinyistudio]

Hi
My UI APP will use the shell to execute two none-ui jars. How do I package them together with B4JPackager11?

B4JPackager11 - the simplest way to distribute UI apps

Better to start with the integrated packager: https://www.b4x.com/android/forum/threads/integrated-b4jpackager11-the-simple-way-to-distribute-standalone-ui-apps.117880/ B4JPackager11 is a B4J non-ui program that builds a package with your app jar and an embedded modularized Java runtime. It...

Correct link is: https://www.b4x.com/android/forum/t...-way-to-distribute-standalone-ui-apps.117880/

Two options:
1. Add them to the files tab and copy them at runtime to XUI.DefaultFolder.
2. Put them in the project folder and follow tip #5 to copy them to the app folder after the package is created.

I always get following exception when i execute other jar from UI-APP(build by B4JPackager11) ?
Exception in thread "main" java.lang.IllegalAccessError: class com.ab.template.main (in unnamed module @0x64c64813) cannot access class anywheresoftware.b4a.StandardBA (in module b4j) because module b4j does not export anywheresoftware.b4a to unnamed module @0x64c64813

    ExecuteJar("execengine",p1,showcmd)
   
    Sub ExecuteJar(event As String,params As List,showwnd As Boolean) As String
    If DetectOS<>1 And False Then
        ' linux

        Dim s1 As String = shl.Arguments
        'shl.Initialize("shl", "cmd" , params)
        shl.WorkingDirectory = File.DirApp
        shl.Run(-1)
        ' shl.RunWithOutputEvents(-1)
        Dim rets As String="java"
        For Each s1 As String In params
            rets = $"${rets} ${s1}"$
        Next
        Return rets
    Else
        ' window
        If showwnd Then
            params.InsertAt(0,"start")

Don't run it with cmd. Run it with java.exe -jar from the java that is inside the bin folder (File.DirApp).

Same result

Dim p1 As List
p1.Initialize  
p1.Add($"-jar"$)
p1.Add($"linegatemt.jar"$)
p1.Add($"alone"$)
ExecuteJar("execgate",p1)

Dim p1 As List
p1.Initialize  
p1.Add($"-jar"$)
p1.Add($"lgmtengine.jar"$)
p1.Add($"${EngId},${linegatePt}"$)
ExecuteJar("execengine",p1)

Sub ExecuteJar(event As String,params As List) As String
    Dim shl As Shell
    shl.Initialize(event, "java" , params)
    Dim s1 As String = shl.Arguments
    'shl.Initialize("shl", "cmd" , params)
    shl.WorkingDirectory = File.DirApp
    shl.Run(-1)
    ' shl.RunWithOutputEvents(-1)
    Dim rets As String="java"
    For Each s1 As String In params
        rets = $"${rets} ${s1}"$
    Next
    Return rets  
End Sub

Start with running it from the command line. It requires some work to find all the required modules.

To run a simple non-ui project:

java -cp nn.jar --add-opens b4j/anywheresoftware.b4a=ALL-UNNAMED  --add-opens b4j/anywheresoftware.b4a.keywords=ALL-UNNAMED b4j.nonui.main

Based on the error message you will need to add more of these "add-opens" arguments.

The result of execution

[Erel]

Error: Could not find or load main class b4j.nonui.main

You need to change it to your package name. I've set the package of the non-ui app to b4j.nonui.

 

[jinyistudio]

my no-ui app use jylab. it is my library(.jar+.xml). Next, how can I put jylab in the ui package ?

D:\jylab\project\b4j\linegateboot\Objects\temp\build\bin>java -cp linegatemt.jar --add-opens b4j/anywheresoftware.b4a=ALL-UNNAMED  --add-opens b4j/anywheresoftware.b4a.keywords=ALL-UNNAMED com.ab.linegate.main

Is this class inside the non-ui jar?

 

[jinyistudio]

Yes

 

[Erel]

Can you upload the non-ui app jar?

 

[jinyistudio]

the jar is too large !

 

[DonManfred]

the jar is too large !

You know GoogleDrive? Dropbox? Have an own server and put the file there and post a link to download?

 

[jinyistudio]

please run with java -jar linegatemt.jar alone

Solution:

1. Make sure that the non-ui has a different package name.
2. Add all the dependencies to the main project.
3. Add to the main project:

#AdditionalJar: C:\Users\H\Documents\...\SecondAppCompiledJar.jar

4. Start the second app with:

java.exe @release_java_modules.txt  -m b4j/second.app.package.main

 

[jinyistudio]

sorry ! What is dependencies ?

 

[Erel]

All the libraries that the secondary app depends on.
