No getter method for property - Problem

Hi Everyone,

I'm new working with Struts and I get an error "No getter method for property author."

Sorry to post the code, but I'm hoping that someone could tell me what
I'm doing wrong. I haven't been able to figure this out and the solutions
in another thread about this don't work.

The code is as follows:


-- Book.java:

package com.mycompany;

public class Book implements java.io.Serializable {

private static final long serialVersionUID = 1L;

private long id;
private String title;
private String author;
private char available;

public Book() {}

public Book(long id, String title, String author, char available) {
this.id = id;
this.title = title;
this.author = author;
this.available = available;
}

public long getId() {
return id;
}

public void setId(long id) {
this.id = id;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public String getAuthor() {
return author;
}

public void setAuthor(String author) {
this.author = author;
}

public char getAvailable() {
return available;
}

public void setAvailable(char available) {
this.available = available;
}
}

============================================================

-- BookListForm.java

package com.mycompany.struts.form;

import java.util.ArrayList;
import java.util.Collection;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

/**
* MyEclipse Struts
* Creation date: 06-24-2008
*
* XDoclet definition:
* @struts.form name="bookListForm"
*/

public class BookListForm extends ActionForm {

private Collection books;

/**
* @return the books
*/
public Collection getBooks() {
return books;
}

/**
* @param books the books to set
*/
public void setBooks(Collection books) {
this.books = books;
}

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

}

============================================================

-- BookListAction.java


package com.mycompany.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.mycompany.form.BookListForm;
import com.mycompany.hibernate.*;
import org.hibernate.SessionFactory;
import org.hibernate.Session;
import java.util.Collection;

/**
* MyEclipse Struts
* Creation date: 06-24-2008
*
* XDoclet definition:
* @struts.action path="/bookList" name="bookListForm" input="/jsp/bookList.jsp" scope="request" validate="true"
*/

public class BookListAction extends Action {

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

BookListForm bookListForm = (BookListForm) form;

SessionFactory factory = null;
Session session = null;
Collection books = null;

try {

factory = HibernateUtil.getSessionFactory();

session = (Session) factory.openSession();

books = session.createQuery("select id, title, author, available from Book t ").list();

bookListForm.setBooks(books);

} finally {
session.close();
}

return mapping.findForward("showList");

}
}

Hi R Diaz,
This is common problem with list in action form, if contains another Bean.
nested tags will help you.
google on struts nested tags.

Hi all,

I get the same error but my getters and setters are well defined. And both "sender" and "retard" are defined as String(s) in my ActionForm.

When it comes to doing <html:text property="sender" /> in my jsp page, it works fine but when I write <html:text property="retard" />, Tomcat gives me the no getter error and I absolutely don't know why as "sender" and "retard" have similar and interchangeable roles.

I have tried turning tomcat off and on again but nothing improved so I'm wondering if there's some tweak I should know to make this work because it's really driving me crazy at the moment.

Thanks in advance.

Regards,
-- Alain
