Hi,
Keep this file in "WEB-INF/classes" and then load it using getResourceAsStream() which will locate the file in the CLASSPATH configured for your application.
I mentioned "WEB-INF/classes" as this is already included in the classpath when webapp starts and loads the classes.

Regards,
Amit

Hi amit,
I have add it but problem is different:

String name=null;
InputStream is = getClass().getResourceAsStream("log4j.properties");
Properties p = new Properties();
try {
p.load(is);

name= p.getProperty("log4j.properties");
} catch (IOException e) {
System.out.println("error loading props...");
}

console error:

log4j:ERROR Ignoring configuration file [null].
means NullPointerException

[amit punekar]

Hi there,

What is this line of code doing?

name= p.getProperty("log4j.properties");

Regards,
Amit

Hi Amit,

This code is return the value of the key that is set in properties. That code is wrong. I have check please give me the proper guideline how to solve this problem that is mention above.

Hello,
Can you tell me
1) If the FileNotFoundException as mentioned in your first post is gone ??
2) You are loading the "log4j.properties" using InputStream into Properties object but you still need to initialize the Log4j by calling
PropertyConfigurator.configure(p). Are you facing error even after doing this?

Regards,
amit

Hi Amit,

Thanks It is running properly.
Where are you from? and give me your contact no or email id.

InputStream is = getClass().getResourceAsStream("log4j.properties");
Properties p = new Properties();
p.load(is);
PropertyConfigurator.configure(p);

regards,
VIVEK
