Cannot find bean: "bookList" in any scope
Hi i'm new at struts.I wanna write all the array elements which i defined at
java class to the jsp file
but i'm getting this error
"javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot find
bean: "bookList" in any scope"
Here is my code
Thx for helping
Book.JAVA
public class Book {
private String name;
private int price;
//private List books=new ArrayList();
Connection con ;
Statement ps;
ResultSet rs;
public ArrayList listBook() throws SQLException
{
ArrayList books=new ArrayList();
try
{
Class.forName("com.mysql.jdbc.Driver");
con =
DriverManager.getConnection("jdbc:mysql://localhost:3306/logintest_development","root","pass");
ps = con.createStatement();
rs = ps.executeQuery("SELECT * FROM books");
while(rs.next()){
books.add(new perInfoBook(rs.getString("title")));
}
}
catch (Exception e)
{
System.out.println("Error Data : " + e.getMessage());
}
con.close();
return books;
}
public class perInfoBook
{
String title;
int bookid;
public perInfoBook(String title) {
this.title = title;
}
public String getTitle() {
return title;
}
public int getBookid() {return bookid;}
}
}
BookForm.JAVA
public class BookForm extends ActionForm{
private List bookList;
public void reset(ActionMapping mapping,HttpServletRequest request){
bookList=new ArrayList();
}
BookAction.Java
public class BookAction extends Action{
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception {
BookForm bookForm = (BookForm) form;
Book book = new Book();
bookForm.setBookList(book.listBook());
return mapping.findForward("success");
}
}
and here is my jsp code
<body>
<logic:iterate id="Table" name="bookList" >
<tr>
<td><bean:write name="Table" property="title"/></td>
</tr>
</logic:iterate>
</body>

Hi All,
also shouldn't it be < logic:iterate name="bookForm" property="bookList" >?
Best greetings,

the short answer is you'll need to populate your arraylist for any of the elements in the list to 'show up'
the long answer is
you'll need to supply jsp/struts-config.xml,struts.xml and backend beans,contents of Action class
and which struts version you are implementing on to be able to provide a solution for you
