Dear All,

As requested by Erel in: https://www.b4x.com/android/forum/threads/retrieving-websocket-data-from-webview.88748/#post-562332

.. here´s a new thread on this topic.
Issue: the WebSocketClient library in b4j does not have an option to bypass certificate security check as it´s the case with b4a´s websocket implementation, where the following solves the problem:

B4X: 
Dim ws1 As WebSocket
    Dim cs As CustomTrustManager
    cs.InitializeAcceptAll
    ws1.Initialize("ws")
    ws1.SetCustomSSLTrustManager(cs)

I´m looking for a way to do the same in b4j.

Thanks in advance for any suggestion!

Complete example:
B4X: 
Sub Process_Globals
   Private fx As JFX
   Private MainForm As Form
   Private ws As WebSocketClient
End Sub

Sub AppStart (Form1 As Form, Args() As String)
   MainForm = Form1
   MainForm.Show
   
   ws.Initialize("ws")
   'accept all trust manager
   Dim ssl As JavaObject
   ssl.InitializeNewInstance("org.eclipse.jetty.util.ssl.SslContextFactory", Array(True))
   Dim jo As JavaObject = ws
   Dim wsc As JavaObject
   wsc.InitializeNewInstance("org.eclipse.jetty.websocket.client.WebSocketClient", Array(ssl))
   jo.SetField("wsc", wsc)
   
   ws.Connect("wss://b4x.com:51041/smiley/ws")
   Wait For ws_Connected
   Log("connected")
   
End Sub

I haven't tested it with a self signed certificate.

Thanks Erel so much, it works! Should I ever bounce into you, remind me that I´m in debt of a bottle of whiskey to you for this :)

Ok, so it does work, but not without glitches.

However, I get various errors at random times. For example:

ws error:
ws error: WebSocket Read EOF

And then it continues till at some point the app decides to not continue. The errors don´t occur in b4a.
I have the feeling of that there´s a memory limit being hit here, like a bottleneck which causes a buffer underrun throwing the error, but that´s just my idea.
It could of course also be something related to the ssl workaround.
It´s very inconsistant.. sometimes it takes a minute, sometimes 30 till I see any of these errors.

Any suggestions?

I don't think that it is related to the unauthorized certificate. Please start a new thread and also include the WebSocket url.

Thanks, may I send you the file in a direct message? Some of the things in there may or may not expose some private data, although I doubt it. Better to be safe though.
