What you want is this -
<s:set name="sessionValue" value="%{accountList}" scope="session" />
However, what i'm wondering right now is this -
you have to expose "accountList" most likely by having a getter/setter
combination on the action that is rendering the JSP that contains this
tag. Assuming you are placing the variable in the session so that you
can retrieve it from another action, why have the object pushed into
the session from a view? I mean, if you have it in an action, why not
push it into the session in that action?
To me, setting session variables from a view smells a bit like
business logic creeping into your view layer. I probably don't know
enough about the task to say for sure, and the tag above should get
the job done, but consider what I'm saying... One of the advantages of
adopting an MVC framework is to abstract business logic away from the
views in your application. If the view performs more than just
displaying the appropriate data, it is potentially less reusable by
different actions (although it doesn't happen a lot that a view is
reused by different actions, it does happen more often if you're
properly disciplined in separating the business logic).
