Hi,
Allow me to ask you a question, that I can not explain. It seems that I really
miss out something with the jsp. Here is my problem, I have a simple jsp that
use java bean ( from a book example), however I narrow it down. If I get the
value directly from bean through scriptlet, then it works fine as Method 1.
However, Method 2 does not work, I could not find what is wrong with it. I
include here the jsp, the output, and java code for the bean. Can you pls look
at the code below and tell me what I have done wrong there? Thanks much for your
helps.
<%@ page import="com.taglib.wdjsp.faqtool.*"
errorPage="error.jsp" %>
<jsp:useBean id="faq" scope="page" class="com.taglib.wdjsp.faqtool.FaqBean"/>
<%
FaqBean[] faqs = (FaqBean[])request.getAttribute("faqs");
%>
<html>
<%
for (int i=0; i < faqs.length; i++) {
faq = faqs[i];
%>
<br>
Using method 1: <br>
Question is: <%= faq.getQuestion() %> <br>
<br>
Using method 2: <br>
Question is: <jsp:getProperty name="faq" property="question" /> <br>
<br>
<% } %>
</html>
</jsp:useBean>
==================
Here is the output (you notice for method 2, the question is null)
Using method 1:
Question is: How can mode 1 format fracture files (.yaa) be converted to reticle
mode format?
Using method 2:
Question is:
Using method 1:
Question is: How can mode 2 format fracture files (.yaa) be converted to reticle
mode format?
Using method 2:
Question is:
=====================================
And the code for the bean is:
package com.taglib.wdjsp.faqtool;
import java.util.Date;
public class FaqBean {
private int id;
private String question;
private String answer;
private Date lastModified;
public FaqBean() {
this.id = 0;
this.question = "";
this.answer = "";
this.lastModified = new Date();
}
public void setQuestion(String question) {
this.question = question;
this.lastModified = new Date();
}
public String getQuestion() {
return this.question;
}
public void setAnswer(String answer) {
this.answer = answer;
this.lastModified = new Date();
}
public String getAnswer() {
return this.answer;
}
public void setID(int id) {
this.id = id;
}
public int getID() {
return this.id;
}
public Date getLastModified() {
return this.lastModified;
}
public void setLastModified(Date modified) {
this.lastModified = modified;
}
public String toString() {
return "[" + id + "] " + "Q: " + question + "; A: " +
answer + "\n";
}
}
