Dynamic links

[Eibhlin Reid]

I have a collection of objects in my action class and I would like to pass it into my jsp and have it display the name of each object as a link. Anybody know how I could do this?

This can be done quite easily with a combination of logic:iterate and html:link tags.

Here is a link to the user guide which explains the details of how to use these tags.

Thanks for your reply, I'm new enough to struts, but I'm using the <logic:iterate tag to iterate through the collection, I am running into trouble when I am trying to take the name of an object out of the collection and display each name as a link. Is there some way to say element.getProperty("topicTitle") and make this the actual link???

<a href='<%= element.getTopicTitle() %>'>Link</a>
or
<a href='<bean:write name="element" property="topicTitle"/>'>Link</a>

They should both work.

I have tried using the code that you suggested, but it doesn't seem to be recognising the element object. My understanding is that the logic iterate tag will take an element off the list that I pass in through the request, this element is of type Topic and has a getTitle() method. Am I able to use the element object from the logic:iterate tag outside that tag? This is the code thats giving me the problem:

<logic:iterate name="topicsList" id="element" indexId="elementNumber" scope="request">
<a href='<%= element.getTitle(); %>'>Link</a>
</logic:iterate>

Thank you in advance!

logic:iterate has a type attribute that you must use to declare what kind of class "element" is.

Add that and you should be all set.

Nope, that didn't work, it still doesn't recognise element!!
