Hi Everyone,

I've seen this error posted several times, but I haven't been able to resolve it. I'm trying to get a tutorial to work without much success. The error I'm getting is "Cannot find bean book in any scope". Can someone please take a look at this and let me know what the problem might be. I appreciate any and all responses.

****** bookList.jsp ******

<logic:notEmpty name="bookListForm" property="books">
<logic:iterate name="bookListForm" property="books" id="books">
<%-- print out the book information --%>
<td><bean:write name="book" property="author"/></td>
<td><bean:write name="book" property="title"/></td>
<td><html:checkbox disabled="true" name="book" property="available"/></td>
<%-- print out the edit and delete link for each book --%>
<html:link action="" paramName="book" paramProperty="id" paramId="id">Edit</html:link>
<html:link action="" paramName="book" paramProperty="id" paramId="id">Delete</html:link>

****** ActionForm *******

public class BookListForm extends ActionForm {

private Collection books;

//get the collection of books
public Collection getBooks() {
return books;

public void setBooks(Collection books) {
this.books = books;

public void reset(ActionMapping mapping, HttpServletRequest request) {
books = new ArrayList();

******* Action class **********

public class BookListAction extends Action {

public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {

BookListForm bookListForm = (BookListForm) form;

//init SimulateDB class and set some dummy data
SimulateDB simulateDB = new SimulateDB();

return mapping.findForward("showList");

**** struts-confi.xml *******

Welcome to JavaRanch!

There's a typo in this code snippet. The id should be "books", not "book." The id is the variable name of the value for that iteration of the loop. It is referred to as "book" within the loop.

Your reply was very helpful. You said the id in the code snippet should be "books" and not "book", but actually the id should be "book" and not "books". Your solution pointed me in the right direction and once I changed the id it worked fine.

Thank you for your quick reply.
