Logging in j2ee

[sachin y deshpande]

Hi
We are facing a problem (File not found) when specifying custom logging properties in a file external to the application.
Please help in figuring out the issue. Thanks in advance.

We have created a custom Logger class which wraps the JDK logger (initiates it too)
We have used the custom Logger to handle logging in web-service implementations.

The following is the code in the custom Logger class

	LogManager logManager = null;
			try {
				FileInputStream inputStream = new FileInputStream("MY_logging.properties");
				System.out.println(" FileInput stream "+inputStream);
				logManager = LogManager.getLogManager();
				System.out.println(" Log Manager "+logManager);
				logManager.readConfiguration(inputStream);
				inputStream.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
			theLogger = logManager.getLogger(CommonResources.getValueForLoggingProperty("log.loggerName"));
		System.out.println(" theLogger "+theLogger);

The following is a section of the MY_logging.properties file that we need to access. This file is supplied in a jar (its in the base directory) which is set in shared-lib of the server. We are using Websphere App Server v7

	#EM Specific properties
       log.loggerName=EMLogger

The following is the exception which we get:

Your logging config file is not being picked up in the CLASSPATH, you might need to play around with how you are deploying it. Maybe try placing in the WEB-INF/classes dir
