AsyncAppender and SocketAppender work together???

[Girish Vasireddy]

Hi all,

1. Can AsyncAppender forward the log messages to a SocketAppender??

I configured a SocketAppender alone and it works fine with the SocketServer. I am 
listening to the events and logging them to a File.
But when I configure the SocketAppender in an AsyncAppender then the file 
are created without any entry in that. 

The problem is as follows,

I am configuring a AsyncAppender which forwards the log messages to a 
SocketAppender and a RollingFileAppender.

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/";> 
<appender name="ASYNC-FOO" class="org.apache.log4j.AsyncAppender">
                <param name="LocationInfo" value="true" />
                <param name="BufferSize" value="5" />
                <appender-ref ref="rappender" />
                <appender-ref ref="sappender" /> 
        </appender>

        <appender name="sappender" 
class="org.apache.log4j.net.SocketAppender"> 
                <param name="RemoteHost" value="AC49101063"/> 
                <param name="Port" value="12345"/>
                <param name="LocationInfo" value="true"/> 
        </appender> 
        <appender name="rappender" 
class="org.apache.log4j.RollingFileAppender"> 
                <param name="File" value="serverLog.txt"/> 
                <param name="Append" value="true"/>
                <param name="MaxFileSize" value="1KB"/>
                <param name="MaxBackupIndex" value="10"/>
                <layout class="org.apache.log4j.PatternLayout"> 
                        <param name="ConversionPattern" value="%d [%t] %p 
- %m%n"/> 
                </layout> 
        </appender> 

<root> 
        <priority value ="debug"/> 
        <appender-ref ref="ASYNC-FOO"/> 
</root> 

</log4j:configuration>  

I configure the above file using  the DOMConfigurator.

DOMConfigurator.configure("async12.xml");

I log the messages shown below ,

logger.error("This is message 1");
logger.error("This is message 2");

The message 1 is logged through the RollingFileAppender, and nothing 
happens after that.

When i change the configuration like

                <appender-ref ref="sappender" />
                <appender-ref ref="rappender" /> 
Then nothing gets logged.

If i remove the <appender-ref ref="sappender" /> then everything works fine with the 
RollingFileAppender.

What is wrong with the configuration??
Does AsyncAppender and SocketAppender work together just with the 
configuration? 

Thanking you in advance
