也就是那种同一个client session的相同的reference
如何让container知道 是同一个client session？
多谢了！ |

I have worked and reviewed >10 applications. No application uses stateful
session bean. In real world, I think stateful session bean and entity bean
are rarely used.

那么在HttpSession里面存放一个stateful session bean的reference
和先new 一个普通的java class再放到HttpSession里面有什么区别呢？

with Spring managed POJO bean.

And since Java is no Perl, why beat a dead horse?

发帖数: 192 | 6 The standard way is put a POJO instance in the HttpSession?
But I saw some applicatoins, they put stateful session beans in the
HttpSession
And for avoiding "NoSuchObject Exception", they always create new SFSB in
catch exception block
Are there any issues about the expiration of POJO instances in HttpSessions
and HttpSessions itself and even the SFSBs (this should be handled by the
EJB container)
btw: I know spring framework and Hibernate are better than J2EE, but seems
there are still lots of

I would say that's some... questionable practice.
If you can isolate the piece of code that does this, definitely go ahead and
send it to TheDailyWTF. 8-)

+1. Although SFSBs can be useful in some rich client applications, where
the client can't be trusted, in either the security or the reliability sense
, to properly maintain the session state.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Then how to let the
different JSP pages know they should use the same reference of SFSB and
store the web client's data without HttpSession?
SFSB is used to store the states of the client. I'm confused.

As others have pointed out, it makes very little sense to use SFSB in a web
application. Just maintain the state in HttpSession.
