B4J Question Compiled program won't start

[oldeast]

I am running the B4j packager with the IDE and get no errors. On Win 10, the program seems to install but there is no .."program installed " message at completion. The program shortcut appears but the program won't run. The jar file runs ok too.
The project uses an SQLite database and I move that to a readable location. I tried renaming the program and restarting win after install .. anyone have any suggestions where to start looking...
thanks...

Run the jar from the command line with java -jar <yourjar>
It will allow you to see the error message.

Thanks Erel, its all sorted now, but that will be good for the next project.

Works fine on my win 10, so I asked a friend to try it on another Win10 machine but it won't install on that system...he tried install and run as admin, checked the uploaded file by downloading and reinstalling on my sys with no problems, the install includes java runtime right so there should not be anything else needed?

Thanks

Did he get any error message?

You still haven't fixed the paths issue:

I did change the code for the file copy ...

I uninstalled the program and deleted File.DirApp folder
I checked that the database was in the objects (File.DirApp) folder.
After installation and the first execution, the folder File.DirData("CMS") is created but the database is not copied, it is copied using .jar

Public Sub DBFilePath
    'check if Db already created
        If File.Exists(File.DirData("CMS"),"cms.db3") =False Then
    File.Copy(File.DirApp,"cms.db3",File.DirData("CMS"),"cms.db3")
    End If
End Sub

How is it created in File.DirApp? It cannot be the correct folder.

cms.db3 is in the CMS/Objects folder...its not copied when the .exe runs the first time

I'm sorry but I don't see how I can further help you.
As I wrote many times in this thread you shouldn't use File.DirApp at all.

 

[oldeast]

sorry Erel, I completely misunderstood, apologies.

I was using basing my code on the dbutils example...

File.MakeDir(File.DirApp, "data")
SQL1.InitializeSQLite(File.DirApp, "data/1.db", True)

also a post from Aug 10 2016
The file.DirApp is read only
You're right but you can create a sub dir in DirApp and write there:
Code:
Dim MySubDir AsString = File.Combine(File.DirApp, "SubDir")
IfNot(File.Exists(MySubDir, "")) Then
File.MakeDir(MySubDir, "")
End If

So I have to create the db in file.dirdata if Iwant to compile the program.
