log4j:ERROR Could not read configuration file

[Cezar Apulchro]

I'm getting error when setting up log4j and I don't know how to resolve.
log4j:

# Root logger option
log4j.rootLogger=DEBUG, console, file

#enable JSF logging
log4j.logger.javax.faces=DEBUG

log4j.appender.console.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Redirect log messages to a log file

ContextListener:

package itc.systems.controller;

import java.io.File;
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;


/**

@WebListener(value = "application context listener")
public class ContextListener implements ServletContextListener {
    
    private Logger logger = Logger.getLogger(ContextListener.class);
    
    @Override
    public void contextInitialized(ServletContextEvent event) {
        
        logger.info("**** Context initialization started ****");
        
        ServletContext context = event.getServletContext();
        
        String log4jConfigFile = context.getInitParameter("log4j.properties");
        
        String fullPath = context.getRealPath("") + File.separator + log4jConfigFile;
        
        PropertyConfigurator.configure(fullPath);
        
        logger.info("**** Log4J initialized successfully ****");
        logger.info("**** Context initialization ended ****");
        
    }
    
    @Override
    public void contextDestroyed(ServletContextEvent event) {
        
        logger.info("Context object destroyed.");

You don't have an init parameter called log4j.properties. The value for the log4jConfigFile is null, which can clearly be seen in the error.

[Cezar Apulchro]

I I changed to:

String log4jConfigFile = context.getInitParameter("/WEB-INF/classes/log4j.properties");

and now the log is generated but the error still the same.

my log4j.properties:

[Stephan van Hulst]

The problem is likely that you added a path separator to a path that already ended with a path separator.

The solution is NOT to remove the path separator. Messing with file paths in a web application is asking for trouble.

The properties file should be at the root of your classpath. If so, I believe you don't have to write a context listener to configure log4j, log4j will automatically pick it up.

Put your configuration file in src/main/resources and Maven will copy it to the correct location.

[Cezar Apulchro]

this error is after the change that you told me to do.

[Cezar Apulchro]

and the log file is not generated.

[Mike Simmons]

The error message contains the complete path of the file it is looking for, and not finding.  Study that - does that path exist on your machine?  Does part of it exist, at least?  Which parts exist, and which do not?  Looking carefully there will help you see where the problem is.

[Rob Spoor]

It's the same error. context.getInitParameter returns the value of an init-parameter that has the given name.

Try getting rid of the call to context.getInitParameter completely.

String log4jConfigFile = "log4j.properties";
         
String fullPath = context.getRealPath("") + File.separator + log4jConfigFile;
// probably better:
// String fullPath = context.getRealPath(log4jConfigFile);

Don't use File.separator in URLs or in Java resource paths. They're based on Unix-style paths and never on Windows paths, so the proper separator is always "/", even in Windows. Resource paths should also always be absolute. That is, "/WEB-INF/classes/log4j.properties" and not "WEB-INF/classes/log4j.properties". Using relative resource paths can lead to unfortunate surprises.

[Cezar Apulchro]

After change made:

ServletContext context = event.getServletContext();
        
        String log4jConfigFile = "log4j.properties";
        
        String fullPath = context.getRealPath("") + File.separator + log4jConfigFile;
        
        PropertyConfigurator.configure(fullPath);

Additional note:

Spring Boot produces an executable JAR. If you use getRealPath() to find a "file" within a JAR (or unexploded WAR) it will return null, because there is no "real" path inside a JAR, only a resource path.

It' VERY important to realize that resources often are not files and therefore should not be read via filesystem operations.

I don't be using Spring Boot.

It doesn't matter.

ANY webapp that's inside a JAR/WAR/EAR file will see the same problem for the same reason. However you were playing around with Spring Boot at one time, I believe and since Spring Boot apps are always JARs, I mentioned it specifically.
