Method Summary

long getCreationTime()
          Return the time when this session has been created in miliseconds since 1970.

long getLastAccessedTime()
          Return the last time this session has been accessed in miliseconds since 1970.

SerializableHttpSession getSession()
          Return the HttpSession object associated to its id.

String getSessionId()
          Get the session identifier associated to this HTTPSession.

void setSession(SerializableHttpSession session)
          Associate a new session (set of attributes, ...) to this id.

Method Detail

getSessionId

public String getSessionId()
                    throws RemoteException

Get the session identifier associated to this HTTPSession. This is the primary key of the entity bean.

Returns:: The session id.
Throws:: RemoteException

getSession

public SerializableHttpSession getSession()
                                   throws RemoteException

Return the HttpSession object associated to its id. The main difference with the standard class is that this one is Serializable.

Throws:: RemoteException

setSession

public void setSession(SerializableHttpSession session)
                throws RemoteException

Associate a new session (set of attributes, ...) to this id.

Throws:: RemoteException

getLastAccessedTime

public long getLastAccessedTime()
                         throws RemoteException

Return the last time this session has been accessed in miliseconds since 1970. This method is a shortcut for getSession().getLastAccessedTime (). The reason is that the bean, when directly asked for the time, don't need to deserialize the session representation if not already done (lazy deserialization). If the only thing that changes in an HTTPSession it the last accessed time (and no attributes), the session may not be replicated on other node (to reduce traffic). Nevertheless, the new session is stored in the local bean. Consequently, if a load-balancer with sticky sessions is used, this is no problem (the local, updated, bean is used.

Throws:: RemoteException

getCreationTime

public long getCreationTime()
                     throws RemoteException

Return the time when this session has been created in miliseconds since 1970. This method is a shortcut for getSession().getLastAccessedTime (). The reason is that the bean, when directly asked for the time, don't need to deserialize the session representation if not already done (lazy deserialization)

Throws:: RemoteException
