I am getting following error message, for the "For Each" statement:

custom tag attribute items cannot be runtime expression (value : ${user.getMessages})



(since html tags are not allowable I have replaced them w/< and >, Hopefully you can get an idea of the code)

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

Your message as follows

Here's my "User.java" class FYI

package com.ibm.tutorials.rational;
import java.util.Vector;

public class User {
private String name;
private Vector messages;

// Simple implementation of a set of users -
// only for illustration purposes. Normally users
// would have to be maintained and managed in a database
private static User[] hardCodedUsers = {
new User("Joe"),
new User("Jane"),
new User("Tony"),
new User("Tina") };

public static User[] getHardCodedUsers() {
return User.hardCodedUsers;
}

public User(String name) {
this.name = name;
messages = new Vector();
}

public String getName() {
return this.name;
}

public Vector getMessages() {
return messages;
}

public void addMessage(Message message) {
messages.addElement(message);
}

// Return a User object based on user name or a null if a user
// by that name does not exist

public static User getUser(String username) {
User[] allUsers = User.getHardCodedUsers();
for (int i = 0 ; i < allUsers.length ; i++)
if (allUsers[i].getName().compareTo(username) == 0)
return hardCodedUsers[i];
return null;
}

}

In your tld, did you mark rtexprvalue to "true"?

What version of JSP and JSTL are you using? From your JSTL URI I am aasuming JSP 1.x and JSTL 1.0?

jsp version is 1.1

I do not see <rtexprvalue> in my web.xml ?

Should it be any where else?

The tld in question is probably embedded in your JSTL implementation. You may want to try the 'rt' version of the URI. If I recall correctly, this syntax is:



but you should look it up in the docs (or the embedded tld) that came with your JSTL implementation to be sure.

Should have read your code.
I saw "custom tag" in your subject and assumed you were writing custom tags.
I didn't notice the JSTL tags in your code.

Disregard my previous post.
 
It is sorta covered in the JavaRanch Style Guide.
