Logging Error with Spring+Log4j

[Rajkumar balakrishnan]

I am using Log4j as my logger with Spring. I did everything as per the basic tutorial and tried to write log messages in a log file. But every attempt to this is failed

my web.xml file is

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  </session-config>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

The log4j.properties file is

log4j.rootLogger = INFO, FILE
log4j.appender.FILE = org.apache.log4j.FileAppender
log4j.appender.FILE.file = ${Erp}/WEB-INF/log.txt
log4j.appender.FILE.layout = org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern = [%d{MMM dd HH:mm:ss}] %-5p (%F:%L) - %m%n
log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern = [%d{MMM dd HH:mm:ss}] %-5p (%F:%L) - %m%n

Then in my controller i wrote a code to add message to text file

	private static Logger log = Logger.getLogger(Controller.class);

	

    @RequestMapping(method = RequestMethod.POST)
	public String setupForm(LoginReg model,Model model1) {
    	System.out.println("Inside Login Controller");
    	log.info("Inside a method of Login Controller");
        //log.debug("Inside a method of Login Controller");
    	//log.error("I think there is an error!!!");

No matter what, it's not working. but when i try to print it in console, its printing. Please help me where i went wrong?

Where did you put log4j.properties ? Under WEB-INF ?

Yes it is under WEB-INF folder. As i said earlier there is no problem in detecting the prop file. Because the log messages got printed in console but when i try to write them to a file, it isn't writing. The log.txt file is also under WEB-INF.

Which message? The one printed with System.out.println()?

[Christophe Verré]

What is ${Erp} ? Where does it come from ?

Nope, logger.info(); Do you think i am that much dumb?

From web.xml. Have a look at this.

 <context-param>  
   <param-name>webAppRootKey</param-name>  
   <param-value>Erp</param-value>  
 </context-param>
