RE: SocketHubAppender support in Chainsaw

["Frissaer, Jeroen" <je...@be.unisys.com>]

Mark, I quickly tested out your modifications to Chainsaw to support
connections to the SocketHub.   Here are some issues I found when testing
locally (app and chainsaw):

When using a socket port other than 4445, everything works fine.
When using the socket port 4445 however, things will not work:

- first starting Log4J application, afterwards Chainsaw: Chainsaw gives the
error : Unable to create socket on port 4445, quitting.  Is this because by
default Chainsaw will startup listening to port 4445 that is in used by the
SocketHubAppender?  (This issue should be resolved then when using Chainsaw
remotely)
- first starting Chainsaw, afterwards Log4j application: Log4J application
gives the error:
Log4J:ERROR exception setting timeout, shutting down server socket.
java.net.BindException: Address in use: JVM_Bind

What do you think?

This work is preliminary, and I know that Eric is more interesting in
modifications to LF5...but here are some modifications to Chainsaw that will
support connections to both SocketAppender and SocketHubAppender.  I'm
sending it out to you directly instead of the whole user list to get some
initial feedback.

There is a new "Connect" menu with 2 menu items: "Connect to..." connects to
SocketHubAppenders; "Accept connection on..." supports connections from
SocketAppenders.

You will need to place the included jar in front of the log4j.jar in your
classpath for these changes to take affect.  Use at your own risk as I have
not performed a lot of testing.  Review the changes if you have a chance.
It needs to be cleaned up some, but the basic idea is there.

Eric, I am going to look at LF5 next.  Do you have any recommendations?
