End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.SetFormStyle("UNIFIED")
    MainForm.RootPane.LoadLayout("test1") 'Load the layout file.
    MainForm.Show

Is that class that can't be found in your j2mod-1.06.jar file? I think you should post the full stack trace so we can see in which subs the error occurred.
