When I do like this
<c:choose>
<c:when test="${book.display}">
<eb:glyphicon-status icon="eye-open" value="${book.id}" />
</c:when>
<c:otherwise>
<eb:glyphicon-status icon="eye-close" value="${book.id}" />
</c:otherwise>
</c:choose>
It works fine.
But when I create tag showeye
<%# tag language="java" pageEncoding="UTF-8"%>
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%# taglib tagdir="/WEB-INF/tags" prefix="eb"%>
<%# attribute name="isDisplay" required="true" rtexprvalue="true" type="java.lang.Boolean" %>
<%# attribute name="bookId" required="true" rtexprvalue="true" type="java.lang.Long" %>
<c:choose>
<c:when test="${isDisplay}">
<eb:glyphicon-status icon="eye-open" value="${bookId}" />
</c:when>
<c:otherwise>
<eb:glyphicon-status icon="eye-close" value="${bookId}" />
</c:otherwise>
</c:choose>
And when I put it on the page
<eb:showeye isDisplay="${book.display}" bookId="${book.id}" />
The condition does not work properly. I always got false result.
What is the problem?

I'm running through weird behavior in Spring MVC. I try to make custom login page with spring security.
Here is my simple login page with a link to a style sheet login.jsp:
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>Title</title>
<link href="/resources/css/style.css" rel="stylesheet"/>
</head>
<body>
<h1>Login Form</h1>
<form:form action="/authuser" method="post">
<c:if test="${param.logout != null}">
<i>You have been logout!</i>
</c:if>
<c:if test="${param.error != null}">
<i>Invalid username or password!</i>
</c:if>
<p>
User name: <input type="text" name="username"/>
</p>
<p>
Password: <input type="password" name="password"/>
</p>
<input type="submit" value="Login"/>
</form:form>
</body>
</html>
when I fill out the form and hit submit it redirect me to http://localhost:8080/resources/css/test.css and serves me with stylesheet file!
when I remove the stylesheet link, it works fine and redirects me to the home page.
I need to create a custom JSTL tag which wraps multiple spring form tags. A single tag which produces the below content with custom attribute values as well.
<div class="col-md-4 col-sm-6 cal-xs-12">
<div class="form-group">
<label for="statusCode">Employee Status Code: </label>
<form:input path="statusCode" class="form-control" id="statusCode" value="${statusCode}" />
</div>
</div>
Is this achievable?
create a file formInputFiled.tag inside WEB-INF/tags/form directory.
formInputFiled.tag:
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%# attribute name="id" required="true" rtexprvalue="true" %>
<%# attribute name="path" required="true" rtexprvalue="true" %>
<%# attribute name="label" required="true" rtexprvalue="true" %>
<%# attribute name="value" required="true" rtexprvalue="true" %>
<%# attribute name="parentDivClass" required="true" rtexprvalue="true" %>
<%# attribute name="divClass" required="true" rtexprvalue="true" %>
<%# attribute name="inputClass" required="true" rtexprvalue="true" %>
<div class="${parentDivClass}">
<div class="${divClass}">
<label for="${id}">${label}</label>
<form:input path="${path}" class="${inputClass}" id="${id}" value="${value}" />
</div>
</div>
Add taglib declaration in your jsp like below:
<%# taglib prefix="form" tagdir="/WEB-INF/tags/form" %>
Finally use the new tag like below:
<form:formInputFiled id="statusCode" path="statusCode" label="Employee Status Code:" value="${statusCode}" parentDivClass="col-md-4 col-sm-6 cal-xs-12" divClass="form-group" inputClass="form-control"/>
How can I possibly set a value for a form input field using the form tag library in Spring MVC shown below even if it has no value attribute and is not accepted according to form tld?
<form:input path ="name" id="name" cssStyle="display: none"/>
Not based on requirement:
<input type="hidden" id="name" value="Raven"/>
Don't use a <form:input>? It's for binding to beans.
You can use a regular <input> element ;)
If you want to set its value:
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<c:set var="name" value="Raven" />
<input type="hidden" name="name" value="<c:out value='${name}' />" />
I'm trying to use Spring MVC 3.2.4 & Tiles 3.0.1 with Regexp prefixes in my tiles.xml file. I'm a newbie with Tiles, so I might be doing something wrong, but have been trying to follow things I have read on in the Tiles doc site as well as apply stuff from the tech.finn.no blog.
Unfortunately, when I use completeAutoLoad=true with RegExp prefix in my tiles.xml file, I get stuck in an infinite loop when trying to resolve the view.

I don't think there is anything specifically special in this configuration, so am not sure why I get into an infinite loop. If I replace the CompleteAutoTilesInitializer class with the BasicTilesInitializerClass and use Wildcards (ie: /) instead and replace {1} with {1}/{2}, then the view loads properly (no infinite loop).
Any ideas what I am doing wrong, or is this a Tiles problem?
Found a similar SO issue (https://stackoverflow.com/a/6617343/827480) that pointed out that the regexp is too greedy and tries to match all attributes as well forever, hence causing the StackOverflow. Work around at the moment is to use a less greedy regexp.
Getting some traction under https://issues.apache.org/jira/browse/TILES-572 and http://thread.gmane.org/gmane.comp.apache.tiles.user/612
We have an running application that is developed in struts-2.0.14. In this we used Ajax theme for displaying contents.
This ajax theme is running properly in all browsers except IE9 browsers, In IE9 this ajax theme making problem . The result is showing in new tab instead of showing in target element(div) specified by targets property.
Parent Page
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<s:head theme="ajax" debug="false" />
</head>
<body>
<s:url id="changePwd" action="changePassword" />
<s:div theme="ajax" id="pwdDiv" executeScripts="true" href="%{changePwd}" loadingText="Loading..."/>
</body>
</html>
Inner page
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%# taglib prefix="s" uri="/struts-tags" %>
<%# taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
<s:form action="changePassword" id="resetPassword" name="resetPassword">
<s:textfield name="username" id="username" />
<s:password showPassword="true" name="newpassword" id="newpassword" value="%{newpassword}"/>
<s:password showPassword="true" name="confirmpassword" id="confirmpassword" value="%{confirmpassword}"/>
<s:submit value="Confirm" showLoadingText="false" onclick="clearMsg();" theme="ajax" targets="pwdDiv" executeScripts="true" cssClass="userbutton" />
</s:form>
When Submitting the form in Inner Page the resulting page is popup into new tab. actually it should replace the content of pwdDiv.
Note: the same working properly in other browsers including (IE7,8)
Update:
making showLoadingText as true making the request as Ajax but the values are passed as null (password,confirm password ect,. -all fields)
Adding type="button" in s:submit button solve the problem. Don't know what is behind this !
<s:submit **type="button"** value="Confirm" showLoadingText="false" onclick="clearMsg();" theme="ajax" targets="pwdDiv" executeScripts="true" cssClass="userbutton" />
