log4cxx chainsaw

2 problems:

1. 
I am having problems connecting log4cxx with chainsaw- I get the following
error:
             Connection lost! :: invalid stream header: 3C6C6F67

this is my log4cxx config:
<appender name="countersFileAppender"
class="org.apache.log4j.XMLSocketAppender">
    < param name="RemoteHost" value="localhost"/>
    < param name="Port" value="9000"/>
    < param name="ReconnectionDelay" value="1000"/>
    < layout class="org.apache.log4j.xml.XMLLayout">
         < param name="properties" value="true" />
         < param name="locationinfo" value="true" />
    </layout>
</appender> 
		
2.
I have reconnectionDelay set to 1000 - which i assume is milliseconds, but i
do not see any connection attempts. why is that?

Re: Custom Appender

First. it would be best for you to define your custom appenders in a namespace other than log4cxx.

Second, you declare a constructor, destructor and close method for VirtualAppender, but you did not
provide an implementation.  Unless you compiled and linked in a file that looked like:

#include "VirtualAppender.h"
log4cxx::VirtualAppender::VirtualAppender() {
}

log4cxx::VirtualAppender::~VirtualAppender() {
}

void log4cxx::VirtualAppender::close() {
}

Then the linker would be expected to complain that there was no implementation provided.
