I am trying as explained here, but couldn't get the output that is shown for the second page.
It redirects to the second page but doesn't print the text i entered, rather returns the empty page.
Any suggestions ? i am using spring framework 3.0.2.
helloView.jsp
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hello</title>
</head>
<body>
<h1>${helloMessage}</h1>
</body>
</html>
nameView.jsp
<%#taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Name</title>
</head>
<body>
<h1>Enter your Name</h1>
<spring:nestedPath path="name">
<form action="" method="post">
Name:
<spring:bind path="value">
<input type="text" name="${status.expression}" value="${status.value}">
</spring:bind>
<input type="submit" value="OK">
</form>
</spring:nestedPath>
</body>
</html>
Add this bean class
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>
This bean is responsible for automatically creating an URL mapping for all controllers registered in the file. It takes the fully-qualified class name of the controller (in our case, controller.HelloController) and strips the package name and Controller suffix, then uses the result as a URL mapping.

I'm going to create a website using Spring.
So I created a jsp file, but no matter how I change the source code from today, the jsp file will not be updated.
This is my jsp code
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

I checked the page source on Google Chrome, but the tag was not added to the source after rebooting the local server many times.
I searched a lot and found that source freezing occurred.
So I checked the work file in the following path, but the work file is empty.
C:\dev\apache-tomcat-9.0.58-windows-x64\apache-tomcat-9.0.58\work
Also, I checked the work file in the following path, but it is also empty.
C:\workspace3\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\work
How can I solve this problem?
I have templates/header.html with following code
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
</head>
<body>
<div class="testing" th:fragment="header">
2016 Header
</div>
</body>
</html>
I have templates/index.html with following code
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
</head>
<body>
<div th:insert="header :: header"></div>
<h3>User Registration</h3>
<form action="/AddUser" method="post">
<input type="text" name="fname" id="lname" placeholder="Firstname"
required /> <input type="text" name="lname" id="fname"
placeholder="Lastname" required />
<button type="submit">Insert</button>
</form>
</body>
</html>
I am expecting 2016 Header in index.html. But, nothing is getting displayed.
I am using following configuration in my gradle dependencies
compile('org.springframework.boot:spring-boot-starter-thymeleaf')
Please tell me where i am going wrong.
I have a testt.html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.thymeleaf.org ">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>Advanced Test</title>
</head>
<body>
<form action="#" th:action="#{getClasses}" method="GET">
<br />
<br />
<p style="margin-left: 35px">Submit fully classified package names</p>
Class Name: <input type="text" name="class_name" size="90px"></input>
<input type="text" name="classes" size="90px" th:field="${foo}"></input>
<input type="submit" value="Submit" ></input> <br />
</form>
</body>
</html>
And have the following code in the controller method:
model.addAttribute("foo", "foo");
return "testt";
Why "foo" is not populating in the html? If instead of String i add an object and try to get its variable it works fine.
i think if you want use it like this you should use th:value instead of th:field
You need this th:field=__${foo}__,
have a look at the doc here:http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html
I'm unable to pass variables from a.jsp to b.jsp, following is what I tried and the output. Can someone please help? Thanks.
a.jsp
start including
<jsp:include page="b.jsp">
<jsp:param name="somevar" value="zzzz" />
</jsp:include>
stop including
b.jsp
${somevar}
${param.somevar}
<%=request.getParameter("somevar")%>
output
start including
null
stop including
You have to set your param before include.
start including
<jsp:params>
<jsp:param name="somevar" value="zzzz" />
</jsp:params>
<jsp:include page="b.jsp">
</jsp:include>
stop including
And can u try this in b.jsp:
<%=request.getParameter("somevar");%>
What is output?
Try the following code:
home.jsp
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%# page session="false"%>
<html>
<head>

</head>
<body>
<h1>Hello world!</h1>
<jsp:include page="b.jsp">
<jsp:param name="something" value="something" />
</jsp:include>
<h1>Bye World</h1>
</body>
</html>
In the b.jsp page use the following code.
<%# 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"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<title>JSP Param example</title>
</head>
<body>
<h1>
<c:out value="${param.something}" />
</h1>
</body>
</html>
The output must be

Try to avoid java code in JSP pages as it is not advisable. For more details, have a look at this answer How to avoid Java Code in JSP-Files?
I tried to retrieve the value of a particular variable and alert it.
That is,I wanted to get the value "{"attributes":[{"type":"Text","labels":"Untitled1"}]}
" in that variable. Using the success: function(msg) in ajax ,I alerted the value.
But instead of the required value :{"attributes":[{"type":"Text","labels":"Untitled1"}]}
I am getting the text given below. What is the problem?
1<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

The problem is that you still use the default layout. Try switching to another shipped layout for Ajax-responses:
// In your controller
$this->layout = 'ajax';
