EL/JSTL Help

[Luke]

Hi

This is my bean code

package Foo;
public class Bean {
private int a;
public int getIntA(){return a;}
public void setIntA(int a){
this.a =a;
}
}

My Servlet Code

Bean []MyBeanArray = {new Bean(), new Bean(),new Bean()};
for (int i=0; i<MyBeanArray .length;i++){
MyBeanArray[i].setIntA(i);
}
request.setAttribute("MyObject",MyObject);
request.getRequestDispatcher("/jsp/MyJsp.jsp").forward(request,response);


This is my Jsp code


<%@ page isELIgnored = "false" language="java" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<c:forEach var = "myBean" items= "${requestScope.MyObject}" varStatus ="MyBeanCounter">
Bean value of ${MyBeanCounter.count} is ${myBean.IntA}
</c:forEach>

myBean.IntA prints the beanOject "Foo.Bean@10c94a7"
How do I print the actual value ?

Hi Luke,
Try doing the following..

Either you can change the line

private int a;

to private int intA;

OR change the getter and setter methods to getA() and setA(int a) respectively.

Thanks,

Hi,

without trying it out (so I could very well be wrong ), the only thing that I can see that looks like it needs changing is the ${myBean.IntA} shoud be ${myBean.intA} the EL parser will change this to myBean.getIntA() which you have.

Thanks for your reply. Is that change required for EL to work? As far as i remember that is necessary in tag classes. Is that required for beans?

Luke

Yes.. It is required for beans.

If the bean property name is say "price" the getter method name should be "getPrice()" and the setter method name should be "setPrice(int value)".

(I am assuming that price is of int type).

Thanks,
Chandra

Thanks a lot. It worked.

Thanks

You are correct. The bean law 2 on Pg 350 says that.

Thanks
