Where should I put the log4j.properties file?


Question

I wrote a web service project using netbeans 6.7.1 with glassfish v2.1, put log4j.properties to the root dir of project and use:

static Logger logger = Logger.getLogger(MyClass.class);

in Constructor:

PropertyConfigurator.configure("log4j.properties");

and in functions:

logger.info("...");
logger.error("...");
// ...

but, it is error info(actually, I have tried to put it almost every dir that I could realize):

log4j:ERROR Could not read configuration file [log4j.properties].
java.io.FileNotFoundException: log4j.properties (The system cannot find the file specified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:106)
        at java.io.FileInputStream.<init>(FileInputStream.java:66)
        at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:297)
        at org.apache.log4j.PropertyConfigurator.configure(PropertyConfigurator.java:315)
        at com.corp.ors.demo.OrsDemo.main(OrisDemo.java:228)
log4j:ERROR Ignoring configuration file [log4j.properties].
log4j:WARN No appenders could be found for logger (com.corp.ors.demo.OrsDemo).
log4j:WARN Please initialize the log4j system properly.

the example project could be get from http://www.91files.com/?N3F0QGQPWMDGPBRN0QA8

As already stated, log4j.properties should be in a directory included in the classpath, I want to add that in a mavenized project a good place can be src/main/resources/log4j.properties

You can specify config file location with VM argument -Dlog4j.configuration="file:/C:/workspace3/local/log4j.properties"

You have to put it in the root directory, that corresponds to your execution context.

Example:

    MyProject
       src
           MyClass.java
           log4j.properties

If you start executing from a different project, you need to have that file in the project used for starting the execution. For example, if a different project holds some JUnit tests, it needs to have also its log4j.properties file.


I suggest using log4j.xml instead of the log4j.properties. You have more options, get assistance from your IDE and so on...

For a Maven Based Project keep your log4j.properties in src/main/resources. Nothing else to do!

If you put log4j.properties inside src, you don't need to use the statement -

PropertyConfigurator.configure("log4j.properties");

It will be taken automatically as the properties file is in the classpath.
