  | What specifically do you do in "cacheoperation"?

the session bean method will invoke this method. forgive for the disorder code.

  |     	String key = key1.substring(0,2);
  |     	String value = key1;

  |     	TreeCache cache = CacheFactory.getCache();
  | 
  |     		
  |     		if("add".equals(command)){
  |     			Address add = ((Person)cache.get("/test/p1","p1")).getAddress();
  |     			add.setCity(value);		
  |     			cache.put("/test/a1","a1" ,add);
  |     			
  |     			if("pp".equals(key)){
  |     				System.out.println("Gettttttttttttttbefore:a1=" + cache.get("/test/a1","a1"));
  |     				throw new Exception("throw exception for rollback");
  |     			}
  | 
  |     		}
  |     		else{
  |     			boolean inCache = cache.exists("/test/" + key,key);
  |     			boolean inLoader = false;//cache.getCacheLoader().exists(Fqn.fromString("/test/" + key));
  |     			System.out.println("Exists in cache:" + inCache + "     exists in loader:" + inLoader);
  |     			Object o = (cache.get("/test/" + key,key));
  |     			if(o != null)
  |     				value = o.toString();

  |         System.out.println("Gettttttttttttttafter:a1=" + cache.get("/test/a1","a1"));

CacheFactory.getCache()
