Android Question [RESOLVED] B4A/B4J - SSL Web Server

[Jmu5667]

Hi All

I am attempting to build an SSL Web Server to allow B4A clients ('wss' websockets) connect and send and receive data.

I am getting the following error on the server when the B4A client connects:

Waiting for debugger to connect...
Program started.

This is the server code:

'Non-UI application (console / server application)
#Region  Project Attributes
   #CommandLineArgs:
   #MergeLibraries: True
   #VirtualMachineArgs: -Xbootclasspath/p:alpn-boot-8.1.11.v20170118.jar

Sub Process_Globals

   Public srvr As Server

End Sub

Sub AppStart (Args() As String)
  
   srvr.Initialize("")
   srvr.AddHandler("/test", "Test", False)
   srvr.AddHandler("/ws", "WebSock", False)
   ' // add filter to redirect all traffic from http to https (optional)
   srvr.AddFilter("/*", "HttpsFilter", False)
  
   srvr.Port = 51041 'non ssl
  
   ConfigureSSL(51042)
  
   srvr.Http2Enabled = True
   srvr.Start
  
   StartMessageLoop
  
End Sub

Private Sub ConfigureSSL (SslPort As Int)
   ' // example of SSL connector configuration
  
   Dim ssl As SslConfiguration

   ssl.Initialize
   ssl.SetKeyStorePath("C:\Isle Systems Data\Certs", "jetty.keystore") 'path to keystore file
   ssl.KeyStorePassword = "************"
   ssl.KeyManagerPassword = "************"
   srvr.SetSslConfiguration(ssl, SslPort)
  
End Sub

WebSocket Class

'WebSocket class
Sub Class_Globals
  
   Private ws As WebSocket
   Private timer1 As Timer
  
End Sub

Public Sub Initialize
  
   Log("WebSocket Initialize")
  
End Sub

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
  
   Log("WebSocket_Connected")
   ws = WebSocket1
   timer1.Initialize("timer1", 1000)
   timer1.Enabled = True
  
End Sub

Sub Timer1_Tick
  
   ws.RunFunction("ServerTime", Array As Object(DateTime.Time(DateTime.Now)))
   ws.Flush
  
End Sub

Sub Device_Message(Params As Map)
  
   Log("Device message: " & Params.Get("message"))
  
End Sub


Private Sub WebSocket_Disconnected
  
   timer1.Enabled = False
   Log("WebSocket_Disconnected")
  
End Sub

I have a both project files.

Any help would be appreciated

Regards

John.
