Modifying property file at run time

Question

Hi all..
I have been using properties file for handling few configurations in my project.
whenever i need a change in the file, i had to change it in corresponding file, create a jar file and then introspect it into project and then publish the project.
Is there any other way of achieving it.... can we modify the property file at run time just like we do for JSP pages...
Or any other better way of doing this.. pls suggest..
(am using 10g OBPM)
Have a nice time...
Regds,

Sharma,
write a java class that reads a property file from the external path. make the jar file non-versionable in case you need to update that later. if you are on J2ee container all you need to do it drop the file @ domain root and u shd be good to go.
sample code I am doing this for log4j.properties and application propertied.
public class BPMLoggerUtil {
     // Initializing the default Logger //
     private static Logger logger = null;
     private static final String DEFAULT_PATH = "resources/log4j.properties";
     private static HashMap map = new HashMap();
     * This is the init method
     * @param propertyPath
     public static void init(String propertyPath){
          try {
               if((logger = (Logger) map.get(propertyPath)) == null){
                    Properties properties = new Properties();
                    properties.load(LoggerUtil.class.getClassLoader().getResourceAsStream(propertyPath));
                    PropertyConfigurator.configure(properties);
                    logger = Logger.getLogger(PropertiesHelper.getProperty("resources.test", "AppName"));
                    map.put(propertyPath, logger);
          } catch(Exception ex) {
               ex.printStackTrace();
     }
