In my JSP I have a textbox and two list boxes[which can display
multiple values].
From my database, I have an object [a data object], ListData with
following information returning
string result;
Vector itemList; //list of object 1
ArrayList itemList1; //list of object 2
In my JSP, I have th reference to ListData object, I know I can use
bean:write and get result.
Now, for getting fields within the arraylists, is there any tag which
I can use ?
Yes and no, depending on your desired implementation. Probably the
easiest way I've found is to use the LabelValueBean object and construct
a java.util.List of these objects from your model data. Then, following
the example at http://wiki.apache.org/struts/StrutsWidgets, you can use
the html:optionsCollection element and the "value" and "label"
attributes to retrieve the value and display name (two separate things)
of the item selected in the listbox.
Since I just implemented this late last week, I can post an example if
you'd like...it's pretty straight forward once you grasp how to use it
(although, it was this last part that took me a while too...)
Alternatively, check out the Radio Group section of the above listed
URL, it provides an example using logic:iterate and bean:write but I
don't think it allows for different bean getters...someone please
correct me if I'm wrong.
I have to
-> iterate thru the list, which gets me another dataobject with getter
method.
-> then use dataobject's property
its like a vector inside an object. Any ideas ?
So, if I understand you correctly, you have a bean Foo with a method
getBar() that returns a Collection? If so, you'll want to just set an
attribute on the request with the result of that getter method as I
don't think there's a way to handle it otherwise. I did this last week
also, so if you want, I can post that code as well.
