would this make sense?
i'm not sure about importing rhe realm and overgive a realm to the 
methode backToContext.
can you give me a feedback?

package org.wyona.commons.io;

import org.apache.log4j.Category;
import org.wyona.yanel.core.map.Realm;

/**
  *
  */
public class PathUtil {

     private static Category log = Category.getInstance(PathUtil.class);

     /**
      *
      */
     public static String getName(String path) {
         // Quick and dirty
         return new java.io.File(path).getName();
     }

     /**
      *
      */
     public static String getParent(String path) {
         // Quick and dirty
         String parent = new java.io.File(path).getParent();
         return parent;
     }

     /**
      * Return null if no suffix exists
      */
     public static String getSuffix(String path) {
         int lio = path.lastIndexOf(".");
         log.debug(new Integer(lio));
         if (lio < 0) return null;
         return path.substring(lio + 1);
     }

     /**
      * @return a String with as many ../ as it needs to go back to from 
current realm to context
      */
     public static String backToContext(Realm realm) {
         String backToContext = "";
         int steps = realm.getMountPoint().split("/").length - 1;

         for (int i = 0; i < steps; i++) {
             backToContext = backToContext + "../";
         }
         return backToContext;
     }

     /**
      * @return a String with as many ../ as it needs to go back to from 
current resource to the realm-root
      */
     public static String backToRoot(String path) {
         String backToRoot = "";
         int steps;

         if (path.endsWith("/") && !path.equals("/")) {
             steps =  path.split("/").length - 1;
         } else {
             steps =  path.split("/").length - 2;
         }
         for (int i = 0; i < steps; i++) {
             backToRoot = backToRoot + "../";
         }
         return backToRoot;
     }

}
