B4J Question Raspberry Pi simple led light up cannot work!

[tzfpg]

I try to used jPi4J for simple led light up project but cannot work. Here is my coding

'Non-UI application (console application)
#Region  Project Attributes
   #CommandLineArgs:
   #MergeLibraries: true
#End Region

Sub Process_Globals
   Private controller As GpioController
   Private Pin23 As GpioPinDigitalOutput
   'Private Timer1 As Timer
End Sub

Sub AppStart (Args() As String)
   controller.Initialize
   Pin23.Initialize(23, True) 'GpioPinDigitalOutput
   StartMessageLoop
End Sub

Suppose pin23 get the High value and the led light will turn on but it not.

I used python to write the small project and the light was turn on.

Here is the python code:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
led=23
GPIO.setup(led,GPIO.OUT)
GPIO.output(led,1)

How to make b4j work?

Are you sure that the code runs at all?

Are you running it with B4J-Bridge?

Try to add: Pin23.State = True

yes i'm running with B4J-Bridge, yes i have tested already. but still cannot light up.

Anyone please help me try my b4j source code, i need to know where the problem cause the led didn't light up.

Please, check the Pin numbering.
Here are the pin numbers used by Pi4J lib

Try using pin no 14.
