      I have a method "populateSystemDefs" in SaSystemDef.java file which is given below.

      public static void populateSystemDefs
      (
        String propertiesFile,
        Vector systemDefs
      )
      {
        Properties properties = UtProperties.getPropertiesFromFile(propertiesFile);

        // Look for one or more instances of SystemDef1, SystemDef2, etc.
        String stem = "systemDef";
        int count = 0;
        boolean keepTrying = true;
        while (keepTrying)
        {
         // Build the property key
         String key = stem + String.valueOf(++count);
      Line:49   String entry = properties.getProperty(key);

      ......

      .......

       

      This method (populateSystemDefs) is called from "init" method of "ControlPanelServlet.java" which is given below

      public void init()
      {
        String propertiesFile = this.getInitParameter("propertiesFile");
        Properties properties = UtProperties.getPropertiesFromFile(propertiesFile);
       
        String property = properties.getProperty("persistenceLocation");
        PfPersistenceManager pfManager = PfPersistenceManager.getInstance();
        pfManager.setRootLocation(property);
       
        property = properties.getProperty("propertiesLocation");
        UtProperties.setDefaultLocation(property);
       
        // Setup database access for this application
        ControlPanelServlet.systemDefs = new Vector();
        SaSystemDef.populateSystemDefs("ControlPanelServletSystem", systemDefs);

        ControlPanelMonitor monitor = ControlPanelMonitor.getInstance();
        monitor.setTraceOn();
        //monitor.traceAllToFile(logProperties);
        monitor.traceAllToSystemOut();

        // Setup application sessions collection
        ControlPanelServlet.appSessions = new HashMap();
      }

       

      Help me in resolving this issue.

       

      Thanks in advance.
