RE: Puzzling error with logic:iterate

I think you are missing a jsp:useBean

Not sure if this will help but try this out -


Add a useBean;

jsp:useBean id=books scope=page class=java.lang.Object/

Before ---
html:form method=GET action=addBook.do

HTH!

pl help. i have been wracking my small brain over this
for a few hours and i have no clew.

i am using logic:iterate copybook style; yet, it throws the runtime exception:

javax.servlet.ServletException: Cannot find bean currBook in scope null

the iterate statement is:
logic:iterate id=currBook collection=%= books %
   Next book: bean:write name=currBook property=title/
 /logic:iterate



the complete source is:


%@ page language=java import=My.*
 import=java.util.* %
%@ taglib uri=/WEB-INF/struts-bean.tld prefix=bean %
%@ taglib uri=/WEB-INF/struts-html.tld prefix=html %

My.Book[] books = new My.Book[4];
books[0] = new Book(An Introduction to Algebra, 100);
books[1] = new Book(JSP: An Advanced Course, 234);
books[2] = new Book(JavaScript and JSP Pages, 333);
 System.out.println(Books =  + books);
pageContext.setAttribute(books, books, PageContext.PAGE_SCOPE);

Sorry, ignore my previous message.  Here's your problem;

Change this line;

My.Book[] books = new My.Book[4];

To;

My.Book[] books = new My.Book[3];

I have tested this and it works for me.  Hopefully it will work for you
as well!
