Keeping the result bean - Struggling with Struts:

[Joe Smith]

Hi,

I'm giving my first steps with struts.

Here's the situation: I have created a jsp (say result.jsp) that displays a
table with a set of data calculated in the action, and which has been stored
in a result bean. Normal.

But, in result.jsp, I want to include a link to other action (for instance,
to show a graphic) using the data of the calculated bean.

The only solution I've come up so far is to store the result bean in a
session, ussing an id (for instance, the current timestamp), and have
result.jsp show sth like:

a href="export.do?beanid=myid"

If I don't use an Id, a user that opens a different tab, and arrives to the
same result.jsp will erase the previous value, won't he?

Is there a standard solution to do this?
I don't like storing data in the session, because if my export.do isn't
called, I don't have a choice to remove it from there.

Any pointers are welcome.

Thanks!

Sounds like you are on the right track. If I understood what you
correctly, then these suggestions might help:

*) If you want to store the result bean in the session, store it under
a constant name, ie "resultBean", rather than an id that changes. That
way you will have at most bean of that type in the session (try to
minimize session usage).

*) If the data is easily recalculated, then stick to the request scope
and recalculate/load the data on each request. This saves any data from
going into the session, and the additional calculation time will
probably not even be noticed by the user.
