Passing an ArrayList from a Servlet to JSP
my model returns an arraylist of strings to servlet in the form
ArrayList&l开发者_如何学Pythont;String> currentCustomer = model.getAllCustomers();
i want to pass this arraylist from the servlet to the jsp page. how do i do this? below is what i tried
req.setAttribute("currentCustomer", currentCustomer);
and in the jsp page, i want to use JSTL to loop over each value and display it. how do i do that? its frustrating me to no end. ive scoured the web but to no avail. any help is greatly appreciated.
here is the jsp code
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<body>
<div>
<c:forEach var="customer" items="currentCustomer">
${customer}
</c:forEach>
</div>
</body>
Let's make it work :)
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<c:forEach var="customer" items="${currentCustomer}">
<c:out value="${customer.name}" />
<c:out value="${customer.age}" />
</c:forEach>
P.S. jsp:useBean is another way to go...
P.P.S. I also made a correction in the taglib import. That's one of these hard-visible mistakes when you can look on two different entries and think they are the same :)
its allrite guys, i solved the problem.. thanks for your help..
apparently the code i was using was outdated (thanks internet!) i was writing this on the header:
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
while it should have been
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
It will be smt like
<c:forEach var="currentCustomer" items="${customers}">
${currentCustomer.name}
${currentCustomer.age}
</c:forEach>
加载中,请稍侯......
