B4J Question [JwebsocketClient] + [ Jserver ] are both incompatible in the same project?

[Waldemar Lima]

i am trying to connect on a websocket using websocket client so that the Jserver web server can provide the website . are both incompatible?

Code Module I'm trying to use >

Sub Process_Globals
    Private wsc As WebSocketClient
End Sub

Sub InitWsConnection
    
    wsc.Initialize("wsc")
    wsc.Connect("wss://ws.xxxxxxxx.xxx/function")
    
End Sub

Sub wsc_Connected
    Log("Conected bro")
End Sub

when calling >: wsc.Initialize("wsc"), I immediately get the error below:

I don't think that's the issue, the issue is an SSL error. So may be the page you are trying to connect doesn't have SSL or it's SSL has some issue.

 

[aminoacid]

did you try connecting using "ws" instead of "wss":

wsc.Connect("ws://ws.xxxxxxxx.xxx/function")

so you can connect without SSL?

but if I comment out the line: wsc.Connect("ws:// ...
the error still pops up immediately .

Make a test and use jServer3 instead of the internal jServer (4): https://www.b4x.com/android/forum/threads/jserver3.141323/#content

jServer3 works fine !!

jWebSocketClient is based on jServer3 SDK. Keep using jServer3 for now.
