Initialized GetLogger at the top of the Service class as follows
Private Shared ReadOnly log As ILog = LogManager.GetLogger(GetType(Service))
I have created GlobalContext property for LogName as follows
log4net.GlobalContext.Properties("LogName") = ConfigurationManager.AppSettings("LogPath") & "Service." & Format(Now, "ddMMyyyy") & ".txt"
Logging is done with log.Info as follows
log.Info(strComments)
In this scenario, the log file is created as "null" under Project folder and logging the details.
I want the log location to be "D:\Service\Service.30082012.txt" according to the code above.
What am I missing? Please help me out.
Typically I separate the log4net configuration from my web.config to avoid web application restarts ( How to prevent an ASP.NET application restarting when the web.config is modified? ) when you change the web.config file.
I usually just have a log4net.config file to store all of these settings and I configure it to watch the config file for changes:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
Also I'm not quite sure why you are storing your log file directory outside of the log4net configuration unless it's just easier for you to modify. I typically keep the path in the log4net config like so:
<appender name="File" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="${ALLUSERSPROFILE}/CompanyName/Logs/ApplicationName/%date{MM-dd-yyyy} - Whatever.log" />
Make sure you don't have any log commands before you set the LogName property.
Also check that logname is being set correctly ie, check that
ConfigurationManager.AppSettings("LogPath") & "Service." & Format(Now, "ddMMyyyy") & ".txt"
is not evalulating to null

I have to write Groovy script log in to a text file, I am able to write request and response of any Soap step using context.expand.
To write test request and response I am using:
def request = context.expand('${SoapRequest#Request}')
new File ("D:/RequestFile.txt").write(request)
What I want is to save the log output in a file:
Suggest me a way to write Groovy script log in a text file.
Config way log4j.xml
There is already a file for Groovy log configured in SOAPUI log4j configuration file.
In SOAPUI_HOME\bin\soapui-log4j.xml:
<appender name="GLOBAL_GROOVY_LOG" class="org.apache.log4j.FileAppender">
<errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/>
<param name="File" value="${soapui.logroot}global-groovy.log"/>
<param name="Threshold" value="DEBUG"/>
<param name="Append" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p [%c{1}] %m%n"/>
</layout>
</appender>
<logger name="groovy.log">
<level value="INFO" />
<appender-ref ref="GLOBAL_GROOVY_LOG" />
</logger>
A possible way is to add another custom FileAppender in this config file. If you change this file remember to restart SOAPUI in order that it can load the changes.
Something like this can do the trick:
<appender name="GLOBAL_GROOVY_LOG" class="org.apache.log4j.FileAppender">
<errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/>
<param name="File" value="${soapui.logroot}global-groovy.log"/>
<param name="Threshold" value="DEBUG"/>
<param name="Append" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p [%c{1}] %m%n"/>
</layout>
</appender>
<appender name="MYLOG_CUSTOM" class="org.apache.log4j.FileAppender">
<errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/>
<param name="File" value="/absoultePath/yourlogFile.txt"/>
<param name="Threshold" value="DEBUG"/>
<param name="Append" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p [%c{1}] %m%n"/>
</layout>
</appender>
<logger name="groovy.log">
<level value="INFO" />
<appender-ref ref="GLOBAL_GROOVY_LOG" />
<appender-ref ref="MYLOG_CUSTOM" />
</logger>
Dinamically using Groovy
However it seems that you want to do it dynamically using Groovy script, hence you can use the follow code to get <logger name="groovy.log"> and add a FileAppender to it; in order that you can save the logs in a custom file:
import org.apache.log4j.Logger
import org.apache.log4j.PatternLayout
import org.apache.log4j.RollingFileAppender
// get the groovy logger by name
def groovyLogger = Logger.getLogger('groovy.log')
// pattern Layout
PatternLayout layout = new PatternLayout("%d{ISO8601} [%t] %-5p %c %x - %m%n")
// create a file appender
RollingFileAppender fileAppender = new RollingFileAppender(layout, "/absolutePath/myLog.txt")
groovyLogger.addAppender(fileAppender)
log.info 'someText to the logger'
NOTE: If you don't use an absolute path in FileAppender the log file is saved relative to *SOAPUI_HOME\bin*
When you configure this the rest of logs in Groovy testSteps will be appended to this file. If you want to get only the log for a specific Groovy testStep then you can simply remove the appender at the end of the script:
groovyLogger.removeAppender(fileAppender);
UPDATE:
From you comment: I want to store output for each run, and if I am executing this again it should rewrite the file.
So you want to store output for each run... but you want to overwrite the file if you execute again? This is contradictory isn't?
If you want to overwrite the file instead of append the content you can use setAppend(false):
fileAppender.setAppend(false)
fileAppender.activateOptions()
groovyLogger.addAppender(fileAppender)
I created a web service project that uses Log4Net to log to the event viewer and optionally to a .log file. Everything works great on my machine, when I try to deploy it on another machine it won't even log to the text file or the event viewer. The fact that it's not even writing to the text file makes me think it's not able to find the log4net.dll or something to that effect?
I'm also receiving an error message when it hits the noted line below in my global.asax:
log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the and elements. The configuration section should look like:
section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /
I'm stumped, I have no idea why this isn't working, help!

You are looking for you configuration in your app.config file. To change this you can use:
// Configure log4net using the .log4net file
[assembly: log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.log4net in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.
or
log4net.Config.XmlConfigurator(ConfigFileExtension="log4net",Watch=true)]
as reference:
// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch=true)]
// This will cause log4net to look for a configuration file
// called TestApp.exe.config in the application base
// directory (i.e. the directory containing TestApp.exe)
// The config file will be watched for changes.
I am trying to use log4c for my C application logging. For implementing rolling policy, I used log4c rolling file APIs. I understood from Log4C developers guide that the rolling policy could be achieved by editing the configuration file (log4crc). I tried editing the appender name to a log file path in the configuration file. But the application run without logging. Can anyone please tell me how to implement rolling log mechanism using log4c?
Please see my helloworld application sample and the configuration file below:
#include<stdio.h>
#include"log4c.h"
int main(int argc, char** argv)
{
int rc = 0;
log4c_category_t* mycat = NULL;
if (log4c_init()){
printf("log4c_init() failed");
rc = 1;
}else{
mycat = log4c_category_get("log4c.examples.helloworld");
log4c_category_log(mycat, LOG4C_PRIORITY_ERROR, "Hello World!");
/* Explicitly call the log4c cleanup routine */
if ( log4c_fini()){
printf("log4c_fini() failed");
}
}
return 0;
}
The configuration file looks as follows:

<category name="log4c.examples.helloworld" priority="debug" appender="/home .. /..filename.txt"/>
</log4c>
I edited the last two lines in the configuration file for logging.
Please let me know what is wrong with my log4crc configuration file and how I can use configuration file to implement logging without using log4c rolling policy apis?
I am also new to log4c. But what I understand from your log4c configuration file
you have category name "log4c.examples.helloworld" twice. So when you write log4c_category_get("log4c.examples.helloworld") it is going to check from CRC file and will get appender name.
Corresponding to log4c.examples.helloworld the appender names are "stdout" and "/home .. /..filename.txt". First one is proper as it will give output to screen. The last one is improper. Do not specify file path there. Put name/ string that will correspoond to appender name. And then in appender name you have logdir value where you can specify the directory where your file will get created.
Check whether your log4crc file is included in the helloworld directory
Removing the version number completely works for me:
Change
<log4c version="1.2.3">
to
<log4c>
I have log4net implemented in a Visual Studio 2010 VB.NET Windows service. It used to work, but not anymore.
I have a sub RunTasks that gets started by the service every minute.
When I debug this procedure using a console project in the same solution, the logging works. However when I install the service and run it, and debug it using VS by attaching to the process, I found out that IsInfoEnabled, IsDebugEnabled, IsErrorEnabled etc. are all set to false, and I guess that's why the logging is not working, although RunTasks is executed by the service.
I have the following class, if I understand things right the XMLConfigurator is started before GetLogger.
Imports System.Reflection
<Assembly: log4net.Config.XMLConfigurator(ConfigFile:="LogConfig.xml", Watch:=True)>
Public NotInheritable Class Logging
Private Shared _LogName As String
Private Shared _ilog As log4net.ILog
Private Sub New()
End Sub
Public Shared ReadOnly Property ILog() As log4net.ILog
Get
If _ilog Is Nothing Then
_ilog = log4net.LogManager.GetLogger(LogName)
End If
Return _ilog
End Get
End Property
Private Shared ReadOnly Property LogName() As String
Get
If _LogName = "" Then
'If GetType(MySettings).GetProperty("LogName") IsNot Nothing Then
' _LogName = GetType(MySettings).GetProperty("LogName").GetValue(MySettings.Default, Nothing)
'End If
If _LogName = "" Then _LogName = "DefaultLogger"
End If
Return _LogName
End Get
End Property
End Class
The logging itself looks like this:
ILog.Info("Starting RunTasks ... ")
And here is my LogConfig.xml
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<log4net>
<appender name="textfileAppender" type="log4net.Appender.RollingFileAppender">

I found the answer myself, I had to move the following line of code:
<Assembly: log4net.Config.XMLConfigurator(ConfigFile:="LogConfig.xml", Watch:=True)>
... (see first code block above) to the AssemblyInfo.vb of the solutions startup project. XMLConfigurator has to be executed before GetLogger is.
I have a WCF service with two methods, Ping and PutAddress. Ping works fine, but PutAddress was failing to initialize NHibernate correctly. Narrowing down the issue, I realized that the relevant settings from Web.config were not being read by PutAddress.
Strangely, Ping does have access to the settings from Web.config. I removed all of the NHibernate code and boiled it down to just trying to read the settings. Ping is able to read the settings (returns non-null, values in result are correct) while PutAddress' result is null.
Again, NHibernate is now completely out of the picture. Both methods simply try to read the relevant settings from Web.config. Ping succeeds while PutAddress fails.
Any thoughts?
Interface:
[ServiceContract]
public interface IMyService
{
[OperationContract]
string Ping();
[OperationContract]
Address PutAddress(Address address);
}
Implementation:
public class MyService : IMyService
{
public string Ping()
{
NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration result =
(NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration)
System.Configuration.ConfigurationManager.GetSection("hibernate-configuration");
if (result == null)
{
System.Diagnostics.Debugger.Break(); // Does NOT break, "Pong" returned
}
return "Pong";
}
public Address PutAddress(Address address)
{
NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration result =
(NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration)
System.Configuration.ConfigurationManager.GetSection("hibernate-configuration");
if (result == null)
{
System.Diagnostics.Debugger.Break(); // Breaks, result is null
}
return address; // Return version potentially modified with DB-assigned ID
}
}

Found the problem - one call was from a Unit Test that I hand-coded, which uses MyServiceClient that was generated by Visual Studio when I added a Service Reference. The other call was from a unit test that was created by the Visual Studio (2010) Unit Test wizard, which just instantiated MyService as an object. The VS-generated unit test was running in-process as a result.
I had an odd problem myself. I could not return "DataTable" objects from a WCF operation. I wonder if there could be a problem with returning an "Address" object from a WCF operation as well.
I don't know the complete answer to your question, but I would suggest the following
In your code for PutAddress, try replacing Address PutAddress(Address address); with string PutAddress(Address address); and replace return address; with return "Pong"
By doing so, you will ascertain the flow of execution through your code. Make sure that you are actually breaking and returning null as opposed to returning a null value of address.
If the new code returns null, then you are in fact having trouble reading from the file. I suspect that it will actually return "Pong", indicating that your code is returning Address, which somehow contains null because of WCF weirdness.
