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
