[logback-dev] Logback doesn't write to a log file

[Sara J]

Hello,

I am trying to migrating my code from log4j to logback without changing my
code using log4j-over-slfj.jar
The logger files creates successefully  but nothing  is written in the log
files/console

*I added the following dependencies in my pom file:*

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.1.7</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.7</version>
</dependency>

*This is my logback.xml:*

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
   <property name="USER_HOME" value="c:\\temp" />
   <property name="ENV_PREFIX" value="s1" />
 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

<appender name="ASYNC_TRAN_Logger"

<appender-ref ref="transactionLoggerData" />
</appender>
<logger name="transactionLogger" level="INFO" additivity="false">
<appender-ref ref="ASYNC_TRAN_Logger" />
</logger>
<logger name="FILE" level="INFO" additivity="false">
<appender-ref ref="ASYNC_COM_FILE" />
</logger>

  <root>
    <level value="INFO"/>
    <appender-ref ref="STDOUT" />
     <appender-ref ref="FILE" />
  </root>

</configuration>

*And I am specifying the location of the configuration file before logback
is loaded:*

                        System.setProperty("logback.configurationFile",
fileName);

InputStream inputStream = new FileInputStream(fileName);

LoggerContext loggerContext = (LoggerContext) LoggerFactory
.getILoggerFactory();
loggerContext.reset();
JoranConfigurator configurator = new JoranConfigurator();

configurator.setContext(loggerContext);
configurator.doConfigure(inputStream); // loads logback file
inputStream.close();

Could you please help?

thanks,
Sara
