Hi again, I have done the following test and is working fine:
1. Update my log4cxx.properties file to send all messages through a XmlSocketAppender like this: log4j.appender.A1=org.apache.log4j.net.XmlSocketAppender log4j.appender.A1.Port=4560 log4j.appender.A1.RemoteHost=127.0.0.1 2. Launch Chainsaw with teh following configuration file that specifies it should be using an XmlSocketReceived like this: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration PUBLIC "-//log4j/log4j Configuration//EN" "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"; debug="false"> <plugin name="XmlSocketReceiver" class="org.apache.log4j.net.XMLSocketReceiver"> <param name="active" value="false"/> <param name="decoder" value="org.apache.log4j.xml.XMLDecoder"/> <param name="name" value="MyXmlSocketReceiver" /> <param name="port" value="4560" /> </plugin> <root> <level value="debug"/> </root> </log4j:configuration> This is working OK, Chainsaw registers without problem the new receiver "MyXmlSocketReceiver" and log messages sent by my C++ application are correctly displayed, so clearly the problem was in the SimpleSocketServer that I used. One question, what I initially wanted was to write in a single log file all those messages, but now that Chainsaw allows me to display and include the SocketServer that understands "XmlSocket" formatted messages I was thinking adding to Chain saw code the feature to write in a single log file and I would have all I need plus a nice display... Do you think this is feasible? Does Chainsaw bring the feature not only to display messages but to save them into a log file?
