Hmmmm. Let's see:
1. You code is re-creating the ArrayList each time thru the loop, but not the book. It
should be the other way around.
ArrayList bookList = new ArrayList();
ResultSet res = this.getResultSet(); // okay if you say so
while (res.next()) {
Book book = new Book();
book.setEnglishISBN(res.getString("isbn"));
book.setEnglishAUTHOR(res.getString("author"));
bookList.add(book);
}
request.setAttribute("BookList", books);
return (mapping.findForward("techbooks"));
}
<bean:define id="bookList" name="bookList" scope="request"/>
<logic:iterate id="book" name="bookList">
<td>
<bean:write name="book" property="EnglishISBN" />
</td>
<td>
<bean:write name="book" property="EnglishAUTHOR" />
</td>
</logic:iterate>

Subject: can't find bean using logic:iterator
Hi to Everyone,
I am trying to use the <logic:iterator> tag in my JSP to iterate an ArrayList
object which is supposed to be delivered by a bean, called Book, and I do
repeatedly get the following exception :
[
org.apache.jasper.JasperException: Cannot find bean Book in any scope

Here is a snippet from my Action class, BookAction :
�������� ----------
ArrayList newArrayList = new ArrayList();
Book conn = new Book();
ResultSet res = this.getResultSet();
while (res.next()) {
newArrayList = new ArrayList();
conn.setEnglishISBN(res.getString("isbn"));
conn.setEnglishAUTHOR(res.getString("author"));
newArrayList.add(conn);
}
request.setAttribute("Book", newArrayList);
return (mapping.findForward("techbooks"));
}
struts-config.xml:
------
------
<action-mappings>
������� <action path="/Books.jsp"
����������� type="com.myBook.BookAction"
����������� scope="request"
����������� input="/Books.jsp">
����������� <forward name="techbooks" path="/Books.jsp"/>
������� </action>
�������
��� </action-mappings>
Books.jsp:
-----
-----
<logic:iterate id="conn" name="Book" scope="request" >
<td>
<bean:write name="conn" property="EnglishISBN" />
</td>
<td>
<bean:write name="conn" property="EnglishAUTHOR" />
</td>
</logic:iterate>

Where could I be going wrong ?
Any help/suggestions will be much appreciated.
Bob
