Java log: Remote Config Reader

Logging In Java with the JDK 1.4 Logging API and Apache log4j

If this property is not passed to the logging framework at startup, 
by default, LogManager reads a configuration file located in the 
"JAVA_HOME/jre/lib/" file. This configuration 
file defines the default configuration parameters for the logging
framework to work. It is possible to override the default location 
and specify our own configuration file by passing a command line 
option to the Java runtime as:

java -Djava.util.logging.config.file=configuration file name

import java.util.logging.LogManager;

public class RemoteConfigReader
 private String urlString = "";
 private URL url = null;
 private URLConnection urlConn = null;
 private InputStream inStream = null;
 private LogManager manager = null;
  * The constructor obtains a connection to the URL specified in the
  * urlString object, obtains an InputStream on the URL and
  * calls the readConfiguration(InputStream) of the LogManager class
  * to perform the initialization
 public RemoteConfigReader(){
           url = new URL(urlString);
           urlConn = url.openConnection();
           inStream = urlConn.getInputStream();
           manager = LogManager.getLogManager();
      }catch(MalformedURLException mue){
           System.out.println("could not open url: "+urlString);
      }catch(IOException ioe){
           System.out.println("IOException occured in reading: "+urlString);
      }catch(SecurityException se){
           System.out.println("Security exception occured in class RemoteConfigLoader");
