Philip Prins · Dec 21, 2016

Hello,

Recently i get some errors when connecting my B4A websocket client to the B4J server;

It does happen often but not every time, any ideas what is the problem?

Erel · Dec 22, 2016

Is this the complete error?

Does the client fail to connect when it happens?

Philip Prins · Dec 22, 2016

Hello Erel,
I will post the complete error below, the client disconnects and then reconnects that does succeed.

Are you using the latest version of B4J with jServer v2.70 ?

Philip Prins · Dec 22, 2016

Hello Erel,

I have B4J 4.5 with Jserver 2.60 , will upgrade to check if the problem persists.
Regards and happy holidays ,
Philip

Philip Prins · Dec 22, 2016

Problem remains with B4J 4.70 and Jserver 2.60

Erel · Dec 25, 2016

Are you using JavaObject to enable any debug logs?

Philip Prins · Dec 25, 2016

Hello Erel,

I am not sure i do get this message at start
log4j:WARN No appenders could be found for logger (org.eclipse.jetty.util.log).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

How can i check this?

Regards
Philip

Erel · Dec 26, 2016

Can you post the full logs when you start the server?

Are you using MqttBroker library?

Philip Prins · Dec 27, 2016

Hello Erel,

I did not use the Broker library but it was checked because i tried it before.I now removed/ unchecked the broker library and the problem with Log4J is gone.
I do get an another error message;Unknown opcode: 7
