Link-to-action?
Hi all,
I am a new struts user utilizing it for my uni project. I have reached a point that I do not know how to handle "the struts way" and am really stuck! I spent a lot time on this and I would be grateful for any further info!
I am dynamically producing some search results. I will be turning them into links and I want to pass a parameter.
Is it possible that a user clicking on a link can trigger an action? eg having something like <a href="DisplayItem.do?ItemId=223">
Using JSPs would be easy to do invoking the appropriate method directly the above way.
Using servlets I could just do String itemId=request.getParameter("Itemid").
Since an ActionClass is a servlet could I achieve the same using the Form as a transfer object for the ID property?
If this cannot be done using the struts sequence (Form-Action) then maybe it will be easier forwarding to a JSP? Doing that though will require me using a scriptlet to retrieve the object of interest :( Any better way? (because my Items are nested I am trying to do it through an Action)
In a nutshell: 1) I display a collection
2) I want to somehow select the item that the user clicked, for detailed description
Any help will be really appreciated!
Thank you for your time,
Theo

Dennis,
thank you very much for the prompt reply. I had a brief look at the example
application but upon googling for a link tag in struts I found the following
http://husted.com/struts/resources/linkParam.htm (source code included)
This seems to be exactly what I need (had no time to try using it yet).
I hope this will be useful to all that face similar problems.
All the best,
Theo

Hi
In our current project we are using an adapted version of the Link<X>Tag
class provided with the struts example application. Check out this class
and I hope it is what you need.
Kind regards
Dennis Hunziker
