Something wrong with you context path. According to form you submitting, try this:
<FORM ACTION="${pageContext.request.contextPath}/validate">
Compare this two urls :
http://localhost:9080/LaunchingGateway_Maintance/services/Test
and
http://localhost:9080/validate
So looks like you are missing some context path LaunchingGateway_Maintance

The output which I am getting is
Print: world
The ${message} is not getting printed
Someone please help me with this
Thanks in advance
The message attribute is added to the MODEL in the printHello method:
#Controller
#RequestMapping("/hello")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model)
{
model.addAttribute("message", "Hello");
return "index";
}
}
which will get executed when you make a GET request for /hello (http://host:port/appContext/hello). But you have the below entry in web.xml file:
<welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
and the web container will use this file for appending to a request for / to show index.jsp to the user, as you don't have any handler method mapped to / URL. So, in order to show the message to the user, remove the <welcome-file-list> entry from web.xml and change HelloController to this:
#Controller
#RequestMapping("/")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model)
{
model.addAttribute("message", "Hello");
return "index";
}
}
Get rid of
<welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
And make your request to
http://yourhost:yourport/YourApp/hello
to match your #Controller mapping.
If you make your request to
http://yourhost:yourport/YourApp
and any of the <welcome-file> entries exist, those will be chosen before your Servlet is hit.
I just started learning spring mvc. Trying to follow a hello world sample.
Everything seems to be working fine, except the jsp view is not able to receive the model attribute value set in the controller.
Here's some code.
Controller:
package org.home.webapp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
#RequestMapping("/welcome")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
}

Using <%# page isELIgnored="false" %> helped.
We need to include org.springframework.web.servlet.ModelAndView instead of org.springframework.web.portlet.ModelAndView;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class HelloWorldController {
#RequestMapping("/hello")
public ModelAndView hello()
{
System.out.println("Just Test iNside");
String message = "HELLO SPRING MVC HOW R U";
return new ModelAndView("hello", "message", message);
}

Try this changes may be it will work for you
you can use <th:block th:text="${your_attribut_name}"/>
example controller
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
view
<h1>Message : <th:block th:text="${message}"/></h1>
output
Message : Spring 3 MVC Hello World
I am trying to implement dynamic check box list in Spring MVC with annotations. So, I tried this one out:
In home.jsp:
<c:forEach items="${categories}" var="cat">
<tr>
<td><form:checkbox path="catrgo" value="${category}"
label="${cat.categoryId}" /></td>
<td><c:out value="${cat.category}" /></td>
</tr>
</c:forEach>
And In HomeController:
#Controller
#RequestMapping(value = "/home")
public class HomeController {
#RequestMapping(method = RequestMethod.GET)
public String showForm() {
FeedDomain feedDomain = new FeedDomain();
System.out.println("Called");
CategoryService categoryService = new CategoryService();
try {
List<CategoryDomain> categoryDomainList = new ArrayList<CategoryDomain>();
CategoryDomain categoryDomain = new CategoryDomain();
categoryDomain.setCategory("aaa");
categoryDomain.setCategoryId(11111);
System.out.println("Size is " + categoryDomainList.size());
} catch (Exception exception) {
}
return "home";
}
Now I am going to home.jsp from index.jsp using tags but the problem is that showForm method is not getting called. What can be the reason?
I am posting below the complete flow:
Here is welcome.jsp from where I am calling home.jsp
<body>
<a href="home.jsp" class="btn btn-success btn-large disabled">Get
Us Feeds Now</a>
</body>
Now I have simplified home.jsp which is getting rendered:
<body>
<br />
<span class="badge badge-info"><h1>Chat Booster</h1></span>
<div class="leftHeader">
<h1>
<small>Subtext for header</small>
</h1>
</div>
<br></br>
<br></br>
</body>
And home page controller is :
#Controller
#RequestMapping(value = "/home")
public class HomeController {
#RequestMapping(method = RequestMethod.GET)
public String showForm() {
FeedDomain feedDomain = new FeedDomain();
// model.addAttribute("feedDomain", feedDomain);
System.out.println("Called");
CategoryService categoryService = new CategoryService();
return "home";
}

My jsp pages are in webcontent folder only (not in web-inf). Now I will look for the main issue later but first point is showForm() method is not being called as sysouts are not priting anything at console. If I make home.jsp as default page of the application, then the method is called but not through the given approach. Can anyone comment on this?
Your link is incorrect, you need to call the controller action not the jsp:
<body>
<c:url var="homeLink" value="/home"/>
Get Us Feeds Now
</body>

Try checking your apachelog in the output Window of netbeans and see what's the default mapping of your controller in it, and append that mapping in the index.jsp.
For example in the log you'll find
Mapped URL path [/employee] onto handler '/*.html'
Simply append employee/add.htm in the JSP
Have you considered using #Controller annotated classes? Since spring 2.5 annotations are usually preferred.
Here's an example web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd">
<display-name>Example</display-name>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/example-servlet.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
example-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!--Tell the servlet where to look for annotated methods-->
<context:component-scan base-package="controller" />
<!--if no controller logic is required, mvc:view-controller can be used to simply show a view for a request -->
<mvc:view-controller path="/" view-name="index"/>
<!--Enables many annotations and searches for #Controller annotated methods etc.. -->
<context:annotation-config />
<!--JSR-303 (Bean validation) support will be detected on classpath and enabled automatically-->
<mvc:annotation-driven />
<!--This tag allows for mapping the DispatcherServlet to "/" (all extensions etc)-->
<mvc:default-servlet-handler/>
<mvc:resources location="/resources/**, classpath:resources" mapping="/resources/**"/>
<!--Configures the application to search for views in folder /WEB-INF/jsp/ with the suffix ".jsp"
in controllers prefix and suffix are therefore no longer needed-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />
And an example simple controller:
#Controller
public class ExampleController {
#RequestMapping("/test")
public String test(Model model) {
model.addAttribute("message","Test message");
return "result";
}
}
