Problem with Tomcat 5.5

[Anirban Das]

Iam using Tomcat as webserver for my Struts(1.3.8) web application

For getting localhost logging I have followed the instruction @

"http://tomcat.apache.org/tomcat-5.5-doc/logging.html"

It solved Tomcat logging problem but Iam not getting my application log which I have configured through a seperate log4j.properties file.

My application has environment configuration file as follows

  
 
 public class EnvConfiguration {
 
  private static final Properties props = new Properties();
  private static FileInputStream fis = null;
  private static Logger logger =  Logger.getLogger(EnvConfiguration.class);
  
  
 
  static {
    loadProps();
  }
 
  /**
   * Load up the smtConf properties.
   */
  public static void loadProps() {
    String managedServerName = null;
    String location = null;
    try{
      String os = System.getProperty("os.name");
      if (os.startsWith("Windows")) {
             
    PropertyConfigurator.configure("C:/WrkDir/Eclipse_3.1.2_SMT Workspace/SMT_OCT07MAJ1_1/config/log4j.properties");
      fis = new FileInputStream("C:/WrkDir/Eclipse_3.1.2_SMT Workspace/SMT_OCT07MAJ1_1/config/smtConf.properties");
       
      }else{
        
        managedServerName = System.getProperty("weblogic.Name");
        logger.debug("managedServerName="+managedServerName);
        location = "config/" + managedServerName;
        logger.debug("location="+location);
 
        fis = new FileInputStream(location  + "/smtConf.properties");
        
      }
      if (fis == null){
        logger.error(location  + "/smtConf.properties" + " not found");
        throw new Exception(location  + "/smtConf.properties" + " not found");
      }
     
      System.out.println("############################Loading SMT Configuration File");
      logger.debug("Loading SMT Configuration File");
      props.load(fis);
     
    }catch (Exception e){
       e.printStackTrace();
    }finally{
      if(fis != null) {
        try {
          fis.close();
        }catch (Exception f) {
          f.printStackTrace();
        }
      }
 
    
 
    }
  }
public static String getProperty(String name) {
    String val = props.getProperty(name);
    if (val == null)
    {
     // logger.debug("Property " + name + " not found!");
      throw new RuntimeException("Property " + name + " not found!");
 
    }
    return val;
  } 
 

Neither Iam seeing System.out.println() statements in tomcat console nor Iam able to see the log file in the mentioned in log4j.properties file

The log4j.properties file written for my web application is as follows

    
 
log4j.logger.com.spcs.smt=debug,A2
log4j.appender.A2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A2.file=C:\\WrkDir\\Eclipse_3.1.2_SMT Workspace\\SMT_OCT07MAJ1_1\\logs\\smtGui.logs                 
log4j.appender.A2.datePattern='.'yyyy-MM-dd
log4j.appender.A2.append=true
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
 

log4j.appender.A2.layout.ConversionPattern=%-5p %d{ISO8601} %c [%t] - %m%n

Thanks in advance....

Where did you put your application's log4j.properties file?

[Anirban Das]

Ben,
Thanks for your response. Well I have put the log4j.properties under my <Application Workspace>/config directory.

Iam loading the log4j.properties file by using a static method (known as loadProps()) which is coded in the class "EnvConfiguration"

   
  
public static void loadProps() {
 String os = System.getProperty("os.name");      
if (os.startsWith("Windows")) {             
 
PropertyConfigurator.configure("C:/WrkDir/Eclipse_3.1.2_SMT Workspace/SMT_OCT07MAJ1_1/config/log4j.properties");
 
 

As my application requires to read the configuration file from folder name config in the workspace I have kept it there and tried to load it at starting of the app itself.

Just to mention I have also tried to put it under <WEB-INF> directory but met with no success.

Cheers

I'm not a log4j guru but I'll tell you what I do.

I put log4j.properties in WEB-INF/classes.

That's it.

Tomcat does not look in WEB-INF when building your application's classpath.
It looks in WEB-INF/lib for jar files and in WEB-INF/classes.

Loading it yourself is like jumping through hoops of fire. Why do it?

If you want the properties to only apply to a particular web app, put it where Ben indicated.

I like my settings to apply not only to all my web apps, but to the logging performed by Tomcat itself, so I place mine in $CATALINA_HOME/common/classes.

[Ben Souther]

If you're interested, I just put together a war file that is configured to use log4j to write to TOMCAT-INSTALL/logs/SimpleLog4j.log.

It's up on my server but hasn't been tested except on my machine just now.
http://simple.souther.us/SimpleLog4j.war

Try it if you like.
If it works for you, then I'll consider it tested and put up some links to it.

Ben,
Sorry for that typo.

What I mean't that time was putting log4j.properties under <WEB-INF>/classes and log4j-1.2.8.jar under <WEB-INF>/lib directory
