My web service is using C# and .Net 2.0
When a "handled" exception is thrown during the web service call, the
service should return normally but should log some information so some admin
chappie can look at it later.
So I thought of usnig log4net but don't know how to. After checking on the
net, it seemed easy enough:
1: This is In my web.config file of the web service:
*************************************************************
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
<log4net>
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value="chuckchuck.log" />
<appendToFile value="true" />
<maximumFileSize value="100KB" />
<maxSizeRollBackups value="2" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level %thread %logger - %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingFile" />
</root>
</log4net>
<appSettings/>
<connectionStrings/>
<system.web>
<compilation debug="true"/>
<authentication mode="Windows"/>
</system.web>
</configuration>
2. This is in the class where I have to do the logging:
**********************************************************************
using System;
using log4net;
using log4net.Config;
public class CalculationNotPossibleException : Exception
{
protected static readonly ILog log =
LogManager.GetLogger(typeof(CalculationNotPossibleException));
public CalculationNotPossibleException()
{
}
private String userMessage;
public String UserMessage
{
get { return userMessage; }
set { userMessage = value; }
}
public void logInput(CalculationInput p_calculationInput)
{
log.Debug("Sriram says DEBUG - this text will be in log file");
log.Info("Sriram says INFO - this text will be in log file");
}
}
********************************************************************
3. When my web service is invoked, I know for a fact that the above code
(log.debug .....) is executed. I know the code control comes there, so I
expect there to be a log file called chuckchuck.log created and the above
lines to be printed into that file.
But that doesn't happen.
I don't get any errors (even in eventviewer) from log4net but there is no
log file called chuckchuck.log in my entire system ... I did a search for
all files with this name.
Some people might say I have to create an appender in the log4j section of
the web.config file for the name "CalculationNotPossibleException" which is
my class name that is doing the logging. But the way I see it, the root is
supposed to handle it all, so it oughta work.
In my application, this is the only place I have to log anything. So there
is no other related code anywhere at all.
So what am I missing?
Request - for those people givnig ideas, if you are saying "put the log4j
thingies in a separate config file" etc .... any comments like this ...
please tell me details such as where (location) I am supposed to save the
new config file and how my web service is supposed to pick up the location
of this config file ... etc etc. I.e. - please give precise comments with as
much detail as possible .... I would really appreciate it.
Wherever possible, please give me the code to do whatever I am missing,
whether it be in my C# file or in my web.config or any other config u might
ask me to make.
Thanks and much appreciation,
Sriram Ranganathan
