Static member problem in multiple instance of web application

Question

Problem
I am working on a product which is java based. I have a war file. I have to deploy this war file in JBoss. Further, I need to run multiple instance of this war file in same JBoss instance.
Issue
     In that war file there is servlet Start.java. That servlet calls an other class from its init method. Here is code
public class Start extends HttpServlet
     public void init(ServletConfig config) throws ServletException
          super.init(config);
          DB.loadProperties (�db.properties�);
     } // init
     public void doGet(HttpServletRequest request, HttpServletResponse response)
          throws ServletException, IOException
               } // doGet
     public void doPost(HttpServletRequest request, HttpServletResponse response)
          throws ServletException, IOException
               } // doPost
} // Start
public final class DB implements Serializable
     public static final String     P_UID = "ApplicationUserID";
     private static final String     DEFAULT_UID = "System";
     public static final String     P_PWD = "ApplicationPassword";
     private static final String     DEFAULT_PWD ="System";
     public static final String     P_STORE_PWD = "StorePassword";
     private static Properties           s_prop = new Properties();
public static boolean loadProperties (String filename)
     {    // looks for properties file
s_prop = new Properties();
          FileInputStream fis = null;
          try
               fis = new FileInputStream(filename);
               s_prop.load(fis);
               fis.close();
          catch (FileNotFoundException e)
               log.warning(filename + " not found");
               loadOK = false;
     �}
As you can see if I deployed two instance of this war in JBoss and assume each instance point to its own properties file. The �Static� members are problem.
Restriction
     I am not allowed change the code or logic of the product. I must be able to get some thing outside or apply a patch to solve this problem.
Please Help
Possible option that I have thought
1 Using multiple JVM - Not an option in this project
2 Using multiple JBoss � Not the requirement (need to run only on single Instance of JBoss)
3 Use own class loader for war/ear � don�t know how in JBoss need help.
I am using JBoss 3.2.3
Thanks,

Answer 1

Static members belong to the class. So, you needto
think of multiple JVMs for your problem.Thanks for reply.
don�t know how in JBoss need helpJust guessing... clustered environment MAYBE
RichThanks Rich,
I don�t know how Cluster environment solve my problem. I need more information on your thought. Cloud you explain it.
