getSessionId

public abstract String getSessionId()
Description copied from interface: ClusteredHTTPSessionBusiness
Get the session identifier associated to this HTTPSession. This is the primary key of the entity bean.

Specified by:
getSessionId in interface ClusteredHTTPSessionBusiness
Returns:
The session id.

setSessionId

public abstract void setSessionId(String sessionId)

getSerializedSession

public abstract Serializable getSerializedSession()

setSerializedSession

public abstract void setSerializedSession(Serializable session)

getLastAccessedTime

public abstract long getLastAccessedTime()
Description copied from interface: ClusteredHTTPSessionBusiness
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.

Specified by:
getLastAccessedTime in interface ClusteredHTTPSessionBusiness

setLastAccessedTime

public abstract void setLastAccessedTime(long value)

getCreationTime

public abstract long getCreationTime()
Description copied from interface: ClusteredHTTPSessionBusiness
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)

Specified by:
getCreationTime in interface ClusteredHTTPSessionBusiness

setCreationTime

public abstract void setCreationTime(long value)

getSession

public abstract SerializableHttpSession getSession()
                                            throws javax.ejb.EJBException
Description copied from interface: ClusteredHTTPSessionBusiness
Return the HttpSession object associated to its id. The main difference with the standard class is that this one is Serializable.

Specified by:
getSession in interface ClusteredHTTPSessionBusiness
Throws:
javax.ejb.EJBException

setSession

public abstract void setSession(SerializableHttpSession session)
Description copied from interface: ClusteredHTTPSessionBusiness
Associate a new session (set of attributes, ...) to this id.

Specified by:
setSession in interface ClusteredHTTPSessionBusiness

getEntityContext

protected javax.ejb.EntityContext getEntityContext()
