B4J Question Jetty setting maxIdleTime

[alwaysbusy]

I'm experiencing Timeouts in on the server side streaming audio files. Although these messages appear in the log, the audio file keeps playing.

Searching the net, I should be able to extend this timeout, e.g maxIdleTime=500000. (it is 30000 by default).

I tried:

srvr.SetStaticFilesOptions(CreateMap("cacheControl": "max-age=604800,public","gzip":True,"dirAllowed":False, "maxIdleTime":"500000"))

But I do not think this is the right place to set this param (it is ignored).

It is not a general timeout. It means that there was no activity for more than 30 seconds (during the connection). The connection might have been closed by the client at some point.

That is probably true. It has to load a mp3 of 11Mb. After 7.6 Mb it stops buffering and start playing. When it reaches 30 seconds into the song, it still has plenty of the song into the buffer so it does not communicate with the socket, giving this error.

I solved the issue on the browsers side, but just out of curiosity, where could I set the Jetty idleTimeout parameter in B4J? Is SetStaticFilesOptions the right place?

You can use this code:

srvr.Start
Dim jo As JavaObject = srvr
Dim connectors() As Object = jo.GetFieldJO("server").RunMethod("getConnectors", Null)
Dim timeout As Long = 50000
For Each c As JavaObject In connectors
   c.RunMethod("setIdleTimeout", Array(timeout))
Next

I solved the issue on the browsers side

can you please explain how?
i am streaming mp4 movies on my server and every time i load a video i get after 30sec this error message. everything keeps working fine but i still get this error. can you please tell me how you solved it?

thanx

I am sorry Ilan, but I have absolutely no idea what I would have done

but you wrote that you solved it??

Well, yes, 5 years ago...

And this line gives birth to a new forum wish....

You can use this code:

srvr.Start
Dim jo As JavaObject = srvr
Dim connectors() As Object = jo.GetFieldJO("server").RunMethod("getConnectors", Null)
Dim timeout As Long = 50000
For Each c As JavaObject In connectors
   c.RunMethod("setIdleTimeout", Array(timeout))
Next

Sub Process_Globals
    Private serverHTTP As HttpServer
    Private mPort As Int = 4444
End Sub

Sub Service_Create
    serverHTTP.Initialize("serverHTTP")   
    serverHTTP.Start(mPort)
End Sub

Public Sub GetIdleTimeout As Int()

    Dim joServerHttp As JavaObject = serverHTTP   
    Dim joSrv As JavaObject = joServerHttp.GetFieldJO("[B]server[/B]")   
End Sub

Using the HttpServer library, trying to retrieve the server object, reports the following error.
java.lang.RuntimeException: Field: server not found in: anywheresoftware.b4a.objects.HttpServer

Note that in debug, for object joServerHttp, server object is displayed.

What can we do?

Thank you.

1. You are using the wrong library. You should use jServer.
2. You are posting in the wrong place. Always start a new thread for your questions.
