Re: logic:iterate tag!
OK, so you have an object in session scope under the key 'AFFFiles',
which is an ArrayList containing FileObj instances. Did you mean to fill
it with the FileReceiptFormBean instances instead maybe? If not, what
properties does a FileObj have?

Well, you'll need to expose the objFiles property to the JSP somehow (by
putting it in request/session scope, or in your form bean, for example).
Asuming you've done that, and that you have appropriate getters on your
FileObj, you can access it like this:
logic:iterate id=file name=yourFileObjRef
bean:write name=file property=fileName/
/logic:iterate

RE: logic:iterate tag and form beans
Ok, If I am understanding the question correctly, you should be populating your array list in your bean with a objects of whatever represents a table row (such as an employee object), this object should have the attributes (name, id, address) you would like to render in the columns. Each object in the array will wind up being a table row. -Original Message- From: Brian Kremmin [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 02, 2005 11:02 AM To: user@struts.apache.org Subject: logic:iterate tag and form beans Hello Everyone, This is my first post. I've been watching the list for a while now and I've hit a dead end. This is probably quite simple so any help would be greatly appreciated.

I'm planning to use an ArrayList to store the data and use the logic:iterate tag to expose the elements of the list... however, I'm unsure of the proper structure of all these data objects.

RE: logic:iterate tag and form beans
Example:
DataBean:
public class EmployeeBean(){
private String name = null;
Private String dept = null;
... Getters and setters
}
FormBean:
public class EmployeeForm extends ActionForm{
private Collection employees = new ArrayList();
... Getters and Setters
}
ActionClass:
public ActionForward execute(final ActionMapping mapping,
final ActionForm form,
final HttpServletRequest request,
final HttpServletResponse response) {
EmployeeForm empForm = (EmployeeForm) form;
//getEmployeesFromDatabase should return a collection of EmployeeBeans
empForm.setEmployees(getEmployeesFromDatabase());
return mapping.findForward(display);
}
JSP:
table
trthName/th
thDept/th
html:form action=xyz method=post
logic:iterate id=emp name=EmployeeForm property=employees
trtdhtml:text property=name//td
tdhtml:text property=dept//td

1) I'd tend towards using JSTL rather than the Struts tags when the
functionality is identical.
2) Put an ArrayList of JavaBeans into the appropriate scope (probably
request?)
IOW, your ArrayList will contain a collection of JavaBeans with getters
for each column you want exposed. Say you have a user represented by
firstname, lastname, and ssn. So your bean would have getFirstname,
getLastname, and getSsn methods.
In your Action you'd do something like:
request.setAttribute(users, userArrayList);
In your JSP you'd do something like (in JSTL; struts beans are quite
similar):
table
c:forEach items=${users} var=user
tr
tdc:out value=${user.firstname}/ c:out
value=${user.lastname}//td
tdc:out value=${user.ssn}//td
/tr
/c:forEach
/table
or whatever.
Again, the hour or two of investment in learning JSTL is worth it for
tags that don't explicitly need Struts functionality, but on a practical
level that may not make any difference to you.

Or should the objects in the Arraylist be something other than a form bean? If you just need to display the data, you don't need FormBeans or anything else Struts-specific. Use whatever data structures make sense to your application and pass them to your view (JSP), as others have posted here. If you need to let the user edit and re-submit the data, validate it, re-display it, etc. then you will want to start using FormBeans and the rest of the Struts machinery to manage that. For output-only data, you just need to expose the model (whatever form you choose for that). Struts is model-agnostic. I'm looking for the 'best' and 'proper practice as our standards group is very picky. Any ideas? If you need to satisfy a picky standards group maybe you should ask what *they* consider to be the 'correct' way to do this in your organization :-) L. -- Laurie, Open Source advocate, Java geek and novice blogger: http://www.holoweb.net/laurie - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
