Philip,
I've updated the LoggingEvent serialization code, which should resolve this issue.

Download the latest version of log4j from CVS and you should be able to use Chainsaw V2 to view log4j 1.2.8 socketappender-generated events.
Thanks,
Scott

Thanks for responding to Philip's request so quickly. However, I don't think maintaining serialization compatibility is feasible in the medium term (i.e. by the time 1.3.0 comes out) but time will tell.

As a small reminder of the complexity of this issue, the current change imposes the field name 'categoryName' on 1.4 as well (if we want to preserve serialization compatibility between 1.3 and 1.4).

Anyway, thanks for fixing the problem.

Subject:        log4j 1.2.8 and Chainsaw v2
Hi,

   Is it possible to send events from a program using log4j version 1.2.8 to
Chainsaw v2?  I'm trying to do this with no luck.  It works OK with the
Chainsaw
from log4j 1.2.8.

   My log4jInit.XML file has the following appender for Chainsaw:

            <appender name="CHAINSAW_CLIENT"
class="org.apache.log4j.net.SocketAppender">
                <param name="RemoteHost" value="localhost"/>
                <param name="Port" value="4445"/>
            </appender>

I start Chainsaw v2 first.  It starts up, displays a warning popup - "You
have no Receivers defined...".
I choose "Let me use a simple Receiver:" - SocketReceiver, port 4445.  I
then start my program with
DEBUG messages enabled.  My program gives this error:

        log4j:WARN Detected problem with connection:
java.net.SocketException: Software caused connection abort: socket write
error

In Chainsaw v2, I get this event:

        Level   ERROR
        Logger  org.apache.log4j.net.SocketNode
        Time    2004-05-13 16:21:36,076

org.apache.log4j.net.SocketNode.run(SocketNode.java:143) at
java.lang.Thread.run(Thread.java:534)

Any help would be greatly appreciated.

Thank you,

- Phil
