I am a beginner in Spring following an online tutorial, I have come across this issue "No mapping found for HTTP request with URI [/DemoProject/processFormGreetingTwo] in DispatcherServlet with name 'dispatcher' " on Submmitting a form. As per my understanding the URI is correct This is my project structure. Tomcat server is opening up the URL "http://localhost:8080/DemoProject/processFormGreetingTwo?userName=amy" and giving Error 404.
This is my Controller:
@Controller
public class MembersController {
// show initial form
@RequestMapping("/showForm")
public String showForm() {
return "mermbername-form";
}
// process the form
@RequestMapping("/processForm")
public String processForm() {
return "welcomemember";
}
@RequestMapping("/processFormGreeting")
public String greetMember(HttpServletRequest request, Model model) {
String uName= request.getParameter("userName");
uName= uName.toUpperCase();
String result= "Hi! "+uName+" Have a great day!";
model.addAttribute("message",result);
return "welcomemember";
}
@RequestMapping("/processFormGreetingTwo")
public String greetMemberTwo(@RequestParam("userName") String uName, Model model) {
//String uName= request.getParameter("userName");
uName= uName.toUpperCase();
String result= "Hi! "+uName+" of BigHit Labels. Have a great day!";
model.addAttribute("message",result);
return "welcomemember";
}
}
This is membername-form.jsp, which has the form:
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>Big Hit Labels - Input Form
</head>
<body>
<c:set var="root" value="${pageContext.request.contextPath}"/>
<form action="${root}/processFormGreetingTwo" method="GET">
<input type="text" name="userName" placeholder="Enter your name" /> <input
type="submit" />
</form>
</body>
</html>

On submitting the form , I get expected results for Requests "/ProcessForm" and "/ProcessFormGreeting" but Error 404 for "/ProcessFormGreetingTwo". Please help me figure out where I could be going wrong with this particular request?
