B4J Question Trying to "clone" my app on a MAC.

#Region  Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 400
#End Region
 
Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Dim shl As Shell
    Private taInfo As TextArea
End Sub
 
Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    MainForm.Show
End Sub
 
Sub btnClone_MouseClicked (EventData As MouseEvent)
    Log("clicked")
        shl.Initialize("Clone", "java.exe" , Array As String("-jar", "ShellTesting.jar"))
        shl.Run(-1)
End Sub
 
Sub clone_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
    If Success AND ExitCode = 0 Then  
        Log("Success")  
    Else  
        Log("Error: " & StdErr)
        Log("stdout: " & StdOut)
        taInfo.Text = "StdOut: " & StdOut
        taInfo.Text = "Error: " & StdErr
    End If
End Sub
