Subject [jira] [Commented] (LOG4J2-96) Error with SocketServer
Date Wed, 31 Oct 2012 19:34:11 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-96?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13488138#comment-13488138

Ralph Goers commented on LOG4J2-96:
-----------------------------------

I don't think I understand, or maybe I misunderstood before.  Do you have multiple plugins
each with their own Log4j jars?  The default LoggerContext is the ClassLoaderContextSelector.
With that you will get a new configuration - and hence a new Appender - with each ClassLoader.
But if the Log4j jars are somewhere that they are being shared you will only have a single
AppenderManager that is shared by both Appenders.  So it is important for me to know how you
are using Log4j before I can give you an answer.

> Hello,
> by using your core.appender.SocketAppender and your core.netSocketServer I found a dissent.
> I am using the default setup of the appender with the SerializedLayout. The first send
event to the server is properly deserialized. on the second I get an IOException:
> log4j java.io.StreamCorruptedException: invalid type code: AC 
> I researched the problem and I found a solution here:
> http://stackoverflow.com/questions/2393179/streamcorruptedexception-invalid-type-code-ac
> The appender creates a new output stream for each log event. It writes every time a header.
The listening server don't expect a header the second time. Because of this it crashes.
> Sincerely
> Robert Breunung
