Re: Form data to Vector

Only way to get data into a Vector is by a scriptlet or in your action.

Struts 2's OGNL has a nice way of doing this but unfortunately with S1we're left with dirty scriptlets in JSPs some of the time.

JSTL has a <c:forTokens /> that sometimes comes in handy where youprovide a comma separated list of Strings and iterate through the elements.

Yes, I know how to use the <logic:iterate> to display the elements of a Vector 
(or ArrayList), I just don't see how to put these values into the Vector. I mean if I 
have a Vector (or an ArrayList) property in my form bean, how do I put some of my 
form data into my bean property. Do I need to modify the setters/getters? There must 
be a way to do this...
And yes, you're right, one the data are in the Vector, I can use 
<logic:iterate> to display them.
Thanks for your help,

Take a look at
http://struts.apache.org/1.0.2/api/org/apache/struts/taglib/logic/package-summary.html

you will see this example of implementing a vector via use of strutslogic:iterate in your jsp


<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%
  java.util.Vector vector = new java.util.Vector();
  vector.add(new Integer(12));
  vector.add(new Integer(5));
 %>
<logic:iterate id="myCollectionElement" collection="<%= vector %>">
 Do something with myCollectionElement
</logic:iterate>

Subject: Form data to Vector

Hi,
I have a form with two submit buttons. One should add the content of atext field to a Vector (which is in the form bean?), and the other oneshould point to another page that has access to the Vector values.
I'd like to know how to add form data to a Vector.
Any help would be appreciated.

Thanks a lot,

MB
