In your Action, set your collection to a session attribute:

session.setAttribute(itData, someVec);
Then in your JSP:

Yup. But you can also clean it out of the session yourself.

Depends on what you mean. If it's a read-only collection, then
Hi All,
I want to populate a table with data from a database, so presumably I create a bean on
a jsp which calls the database, and converts it and hands it to an iterator.
First, how do I make the data thread-safe? Is it thread-safe because it is in a jsp
which is therefore compiled into a
Being a bit slow off the mark with this iterator tag. I've found all sorts of examples
and some stuff in the archives here but it's confused me more than helped me.
If I want a list displayed, no form, just data, the best place to get it is in a page
context bean, right?
Second, how do I
In the action that will be forwarded to your jsp you put a list(e.g. an
ArrayList) on the request. This list contains bean of some kind.
Then in your jsp you can write :
logic:iterate id=item name=NameOfMyListOnTheRequest scope=request
bean:write name=item
Yowsa! Someone is listening. I've just got a bit of pressure on, which doesn't make it
easier. I did actually get that far in the thought process, but several Actions can
forward to this page, so can't I just do the stuff in a bean a tag?
How about ditching the seperate bean subclassing the
You probably could do that but I'm pretty sure it will not be fast developping.
Also I think it is not the right way to do struts.
Just do what you have to do in a simple java action and throw your stuff on the
request or the session ( if the data needs to live longer then one request ) .
Sorry, I missed the point with the forwarding completely. I can change the action
mapping in my struts-config to go to the new action instead of the jsp, right?

Adam, I've just cracked this myself.
In your Action, set your collection to a session attribute:
Vector someVec = valueBean.getSomeData();
session.setAttribute(itData, someVec);
Then in your JSP:
logic:iterate name=itData id=list scope=session
...
/logic:iterate
Hope this helps,
James.
