Accessing session attributes

[James Howe]

This is probably a stupid question, but here it goes.  I have a handful of 
string values that I'm storing in the session object.  These values aren't 
associated with any bean (actually, in a sense the session object is the 
bean).  I have a couple of places where I need to display these values in a 
form.  I want to use the html:text tag, but I don't know what I need to 
specify.  Let me give an example.  Suppose I have a String value stored in 
the session by the name of filter.  How would I get the filter value to 
display in a form text field?

Thanks.

[Charlesworth, Chico]

u probably just need to specify 'filter' in the name attribute ...

like bean:write name=filter

it should try and find filter in the session, page, request, and
application scopes ... in which order i can never remember ;)

chico.

Hi!

You can access session attributes and their values by using the bean:write
tag. For example - in the following tag myScheduleWeekDayStopTime is a
session attribute. (Here the value is written on the form as plain text and
not in a text field).

Hope this can help!

/Linnéa

td class=text_b align=left nowrapbean:write
name=myScheduleWeekDayStopTime//td

The html tags are designed to display what's in a related ActionForm
bean. So the trick would be to get your String into the ActionForm bean.
The place to do this would be in an Action that then forwarded to your
JSP. So the Action would go something like this:

HttpSession session = request.getSession();
YourBean yourBean = (YourBean)
session.getAttribute(yourBean);

YourForm yourForm = (YourForm) form; 
yourForm.setWhatever(yourBean.getWhatever());

return (findForward(success));

You could use the same Action to handle the submit from the form, either
by keying on a value in the form or by submitting to another Action
Mapping with a different parameter property.

If you don't need to display them in a HTML form, then you can just use
the bean:write tag and specify the property you want to write (assuming
it has a getYyyy accessor).

You can use the bean:write name=foo/ tag to simply write out the value
of a string stored under key foo to the output page.  However, if you
want to pre-initialize a field to be displayed by html:text, you need to
arrange to call the appropriate property setter on your form bean.
