Memcache Java API /deserialize issue

[Manoj Kumar]

Thanks for giving reply greg  . Actually i am passing the Tomcat5.5.4 
StandardSession to memcached sever.


  StandardSession. is serializable Class please check following class 
definition

       public class StandardSession  implements HttpSession, Session, 
Serializable

  Here is my code .

//   mysession is serialized object
     StandardSession  mysession = (StandardSession) session;

    MemCachedClient mc = new MemCachedClient();

     boolean flag = mc.set(session.getId(),mysession);

     log.info("is Standard session  stored into memcahe  ::: "+ flag);
//    flag is true after the above statements  are executed

     StandardSession _mysession =(StandardSession) mc.get(session.getId());
     log.info("calling _mysession from memserver  ::: "+ _mysession);

//    _mysession is null...that's the problem
