[jinyistudio]

Hi

I try my first b4j program but i always get a message as attached image file.
this message tell me it couldn't found my controller "jinyistudio.controller".
My form just have one botton inside.

#Region  Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 400
#End Region

#AdditionalJar:j2mod-1.06

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Private button1 As Button
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   
End Sub


Sub button1_Action
   
End Sub

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.

It is ok when i use internal designer to create layout. Why ?

 

[Erel]

What is j2mod? Why are you adding it to your first B4J project?

You should use the internal designer for new projects. Scene Builder is left for backwards compatibility.

Hi
j2mod is a modbus library. I have remove it,the result is not ok(same) too.

 

[Erel]

The problem is in the fxml file. However you should just avoid using Scene Builder.
