Using Hashtables in ResourceBundles

Name: rm29839 Date: 11/11/97


Hi,

Sorry if this is user error; but the following
ResourceBundle returns a NullPointerException
during RB.handleGetObject("routeNameNull").

java.lang.NullPointerException
        at mp/MPResourceBundle.handleGetObject
        at java/util/ResourceBundle.getObject
        at java/util/ResourceBundle.getString
        at mp/MPException.toLocalString
        at mp/MPTest.main

Seems as though ClassLoader can load a class
but never fires the constructor for the loaded
class. I can step into handleGetObject; but
Res returns null for "routeNameNull". Apparently
there are additional requirements to using
Hashtables, static arrays work ok. Thanks.

     public MPResourceBundle()

          Hashtable Res = new Hashtable();

          // Load US English Resources
          Res.put("nullFilenameSave", "Cannot save to null filename.");

          Res.put("nullFilenameRestore", "Cannot restore from null
filename.");
          Res.put("routeNameExists", "Route name already exists: {0}");

          Res.put("routeNameNull", "Route name cannot be null");
          Res.put("routeNameNotFound", "Route namd not found: {0}");
     }
     public Object handleGetObject(String key) { return Res.get(key); }
     public Enumeration getKeys() { return Res.keys(); }
}
