Personally, I would just write my own helper class:

public class MyPropertiesHelper
{
     private Properties props;

     public void load( Object filepath)
     {
         FileInputStream fis = ...;
         props.clear();
         props.load( fis);
     }

     public Object get(Object key)
     {
         return props.getProperty(key.toString());
     }

     public Object put(Object key, Object value)
     {
         return props.setProperty(key.toString(), value.toString());
     }
}


An -new- instance of this can then be put into your context for every 
request, or you can wrap it in a contexttoolloader/factory so that you 
automatically get a new instance for every request.

...or you add a simple factory that you put into the context instead:

public class MyPropertiesFactory
{
      public MyPropertiesHelper newInstance(Object filename)
      {
           MyPropertiesHelper h = new MyPropertiesHelper();
           h.load(filename);
           return h;
      }
}

Cheers
