java.io.IOException: Couldn't get lock for applicationLog.xml

Hi Experts
im working with tomcat5 and use java logging api for logging perpose.
But When I run the application it will create huge number of files(0
bytes) in tomcat bin folder
with following exception.

java.io.IOException: Couldn't get lock for applicationLog.xml

This is my own logger class constructor:
-------------------------------------------------------------------------

    public CLogger( String className ) {

        try {
            this.logger = Logger.getLogger( className );

            // set log level to ALL as default
            this.logger.setLevel(Level.ALL);
            int limit = 1024 * 1024; // 1 Mb
            // Create a new handler that uses the XML formatter
            fileHandler = new FileHandler( logFilePath + logFileName,
limit,
1, true );
            // set File formatter
            fileHandler.setFormatter( new XMLFormatter() );
            fileHandler.setLevel(Level.WARNING);
            // set handler
            this.logger.addHandler( fileHandler );

        } catch (Exception e) {
            e.printStackTrace();
        }

    }
-------------------------------------------------------------------------

Thanks in advance
