Thank you for your help.
I have tried your suggestion, but it still does not work since the properties
file does not locate loosely in the system. It is embbeded inside a jar file.

Here my situation:
  I have a war file which contains several jar files. The properties file is
embbeded inside one of the jar file.
  I tried to load that properties file and I have tried this way

      String name = "com.myjar.resources.log.properties";
      InputStream st = ClassLoader.getSystemClassLoader().getResourceAsStream
(name);

  It can not find the properties file

Is there the way that I can open a file embedded inside a jar file?

Sure. Here is an example of finding the 'Object'
class by it's name - note
a) the '/'s
b) the firstmost '/' of the successful string.

<sscce>
class GetResourceTest {
public static void main(String args[]) {
   Object o = new Object();
   String location = "java/lang/Object.class";
   java.net.URL url = o.getClass().getResource(
     location);
   System.out.println( url );
   url = o.getClass().getResource(
     "/" + location);
   System.out.println( url );
}
}</sscce>
