I'm starting to study struts and I have a problem using resource properties file
some text on page is displayed as this:
???login.message???
???login.username???
???login.password???
but some other messages are correctly taken from properties file. I think that the propertis file is correctly configured but I'm missing something to display anything correctly.
the file ApplicationResources.properties
# Resources for Login Project
# Struts Validator Error Messages
# These two resources are used by Struts HTML tag library
# to format messages. In this case we make sure that errors
# are red so that they can be noticed.
errors.header=<font color="red">*
errors.footer=</font>
#errors associated with the Login page
error.username.required=username required.
error.password.required=password required
error.login.invalid=The system could not verify your username or password. Is your CAPS LOCK on? Please try again.
#login page text
login.title=this is a title
login.message=please log in
login.username=username:
login.password=password:
login.button.signon=Log In
#loggedin page text
loggedin.title=Login Project
loggedin.msg=Benvenuto, {0}. You are now logged in.
"error.login.invalid" is correctly displayed and "error.username.required" too
the login label not
this is my jsp page

Can you help me ?
tkz
Your
<fmt:message ... />
tags need to be inside an
<fmt:bundle ... >
tag. Currently you are closing your bundle tag right away
<fmt:bundle basename="ApplicationResources"/>
Instead, open it
<fmt:bundle basename="ApplicationResources">
and close it
</fmt:bundle>
when you no longer need it, possibly at the end of your JSP. Nest your
<fmt:message key="login.title"/>
tags inside it.

I am currently working on a small web app project. The homepage has a link that, once clicked, calls a servlet that retrieves data from a database (in the form of an arraylist of objects), adds arraylist to session(as customers), and redirects to a jsp where the objects (customers) are displayed in a table. There is a "more details" column where each row has a button which submits a form, to another jsp, with a hidden input value with customerNumber as its value and num as its name.
I want, in the second jsp, to loop over all customers and only display the one whose customerNumber matches the one sent from the first jsp.
Current code:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<% String hidden = request.getParameter("num"); %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Customer Details Page</title>
</head>
<body>
<div>
<c:forEach var="c" items="${customers}">
<c:if test = "${hidden == c.customerNumber}">
<table>
<thead>
<tr>
<th>Customer Phone</th><th>Customer Country</th>
</tr>
</thead>
<tbody>
<tr>
<td>${c.phone}</td><td>${c.country}</td>
</tr>
</tbody>
</table>
</c:if>
</c:forEach>
</div>
</body>
</html>
The above code only prints the table heading. Any help appreciated.
Found the issue, was trying to access variable from scriplet directly from jstl tags. The following code works fine:
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String hidden = request.getParameter("num");
pageContext.setAttribute("reqNum",hidden);
%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Customer Details Page</title>
</head>
<body>
<div>
<c:forEach var="c" items="${customers}">
<c:if test = "${reqNum == c.customerNumber}">
<table border="1">
<thead>
<tr>
<th>Customer Phone</th><th>Customer Country</th>
</tr>
</thead>
<tbody>
<tr>
<td><c:out value="${c.phone}" /></td><td><c:out value="${c.country}" /></td>
</tr>
</tbody>
</table>
</c:if>
</c:forEach>
</div>
</body>
</html>
Instead of using
<td>${c.phone}</td><td>${c.country}</td>
You can try:
<td><c:out value="${c.phone}" /></td><td><c:out value="${c.country}" /></td>
I want to redirect a client to following paths when a particural text is clicked, but only Query and Remove works properly. My contextPath is "basics" and the jsp is displayed with path "http://localhost:8080/basics/". When i click on Update or Add user, then it redirects me to "http://localhost:8080/basics/basics/users" (the jsp file is users.jsp) but it should redirects respectively to "http://localhost:8080/basics/user/update/${customer.id}" and "http://localhost:8080/basics/user/add" What's wrong with that code?
users.jsp:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<c:forEach var="customer" items="${customers}">
<c:set value="${contextUrl}/user/update/${customer.id}"
var="updateUserUrl" />
<c:set value="${contextUrl}/user/remove/${customer.id}"
var="removeUserUrl" />
<c:set value="${contextUrl}/user/${customer.id}" var="userUrl" />
<tr>
<td><c:out value="${customer.id }" /></td>
<td><c:out value="${customer.name }" /></td>
<td><c:out value="${customer.age }" /></td>
<td><c:out value="${customer.country.country }" /></td>
<td style="background-color: #17D0F5"> Query </td>
<td style="background-color: #FF8000"> Update </td>
<td style="background-color: #EC2727"> Remove </td>

</c:forEach>

Try to replace this:
Add user
With using double quote "" and adding var="userVar":
Add user
And use the ${userVar} where you want.

What I want to do, using a simple textbox I want to be able to filter the table displayed using the code above, I believe I can do it using jQuery but is jQuery compatible with Expression language or is there any other method I can make use of?
Despite the fact almost nobody will support you in what you are doing :) .. I mean all is in JSP..
The exact answer is the following:
Add an html form with a textbox.
Add code that reads the textbox value as request.getParameter().
http://www.tutorialspoint.com/jsp/jsp_form_processing.htm
Add the value from (2) into your query <sql:param value="..." /> and add where clause. Perhaps, you will need IF for two cases: a) filtering off - no text value and no where b) filtering on - text value exists and where used.
This will be a server-side processing (filtering) though.
If you want client-side filtering consider using DataTables http://www.datatables.net/
