outputText won't show anything / cannot access class?

outputText won't show anything / cannot access class? - java

So I'm new with this JSF stuff and thought I write some code just to see how it works. Actually I did things like here in this tutorial. But I'm not even able to do the simplest thing.
To keep things clear I just made one class:
#ManagedBean
#SessionScoped
public class Bean implements Serializable {
private static final long serialVersionUID = 1L;
public final String TEXT = "Bean";
}
my index.xhtml:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://xmlns.jcp.org/jsf/passthrough">
<head>
<meta charset="UTF-8"/>
<title>JEE</title>
</head>
<body>
<h3>Output1: <h:outputText value="#{Bean.TEXT}"/></h3>
<h4>Output2: #{Bean.TEXT}</h4>
</body>
</html>
If I start this on Eclipse I dont get any output for Bean.TEXT , like if I would not have any access to this class:
So there should be some text after Output1 and Output2. I don't see any exceptions regarding the Bean class. How do I debug stuff like this? Any suggestions?
PS:
Here my web.xml (I made it somehow like in the tutorial):
<?xml version="1.0" encoding="UTF-8"?>

Within EL context you access beans via names that were previously declared by means of annotations or configuration file. If you don't specify name element of #ManagedBean annotation then it'll become the simple class name with the first letter decapitalized (if two initial letters are not uppercase). In your case the bean can be accessed as #{bean} while you tried to access it as #{Bean} which is wrong (but could have worked if you declared it as #ManagedBean(name="Bean")).
Also, it's worth noting that it is a common practice to have only one mapping for the faces servlet and that is *.xhtml, so you'd be better off if you removed the three specified servlet mappings from your web.xml and left only one.

How to handle this warning?

In your controller you should define the RequestMethod in RequestMapping:
#RequestMapping(value = "/Add", method = RequestMethod.GET)
After defining the request method, you should use to call this method by giving the request method:
<form:form id="addForm" action="${pageContext.request.contextPath}/Add" method="get">
<button type="submit">Go to Add method</button>
</form:form>
You can follow the same procedure for Post requests.

Spring MVC .jsp is not being created by ViewResolver automatically

im new to Spring MVC.when I run the project welcome.jsp gets open. then I fill in the form and press login. Its all as it should be until now but then I want the success.jsp to open if the userID is didem and the passqord is 123321 if not then welcome.jsp should reopen.. but what I actually get is 404 not found
because in the web browser the url link is like this: http://localhost:8080/CrunchifySpringMVCTutorial/welcome
Idk why the viewResolver doesnt put a .jsp at the end.. Any help would be appreciated ..

what about return "redirect:/{welcome}"; as shown below.
#RequestMapping(value = "/welcome", method = RequestMethod.POST)
public String verifyLogin(#RequestParam String userID, #RequestParam String password){
ModelAndView model = new ModelAndView();
model.addObject("loginError", "Invalid Id AND/OR password");
if(userID == "didem" && password == "123321")
{
return "success";
}
return "redirect:/{welcome}";
}
}

No error in apache but I get a 404 error

I have been at this for a day now and cannot understand why it is not working. I followed a tutorial, read the spring documentation and still do not understand, even better there are on errors to go off of.

Final notes:
Use Spring webmvc jar. checkpom.xml all you need is this.
Add to offers-servlet.xml . Check below notes for
-Don't use run on server inside eclipse and make the request to http://localhost:8080/offers/ from a browser.
The caveat to overriding the "/" Servlet mapping is that the
RequestDispatcher for the default Servlet must be retrieved by name
rather than by path. The DefaultServletHttpRequestHandler will attempt
to auto-detect the default Servlet for the container at startup time,
using a list of known names for most of the major Servlet containers
(including Tomcat, Jetty, GlassFish, JBoss, Resin, WebLogic, and
WebSphere).

Cannot Resolve Views inside WEB-INF/ folders using the jsp filename as RequestMapping value

Ok this is always a problem for spring beginners, there could be tons of similar problems out there, but every time I type this issue, I always end up reading indirect solutions which I cannot understand, just like what the title said, I cannot resolve views(jsp) inside my WEB-INF/views folder, if i map the page using the file name.
Update: I've been searching extensively with a noHandlerFound/NoMapping Found for a URI problem, I just learned that the controller class name will be resolved by ControllerClassNameHandlerMapping removing the controller and lowercasing the non-controller name and it will be used as the url,
but I CANT still get to load my very simple page in start-up, and no matter where I search there are always tutorials that gives the same example, it does not work. please I need help here.. :(

Everytime I run this very simple web application on start,
The servlet resolves the view and display the content of the page by this URL
http://localhost:8080/ProductsHome/
but when I refresh the page, it results into a 404 error
and I need to manually type the file name of the jsp to resolve the view
http://localhost:8080/ProductsHome/productsHome
This is the kind of code I always see in the tutorials I'm reading especially spring-recipe book, but I cannot make it work the way it was said in the book, I expect that on the first start-up the dispatcher-servlet will resolve the views and displaying the page with this URL below
how can I make this work? any help would be greatly appreciated.
http://localhost:8080/ProductsHome/productsHome/home
here is the server log I get so far, I'm currently searching what I need to add to eclipse to show any error

I thing the controller should be
#Controller
#RequestMapping(value = "/welcome")
public class WelcomeController {
#RequestMapping(method = RequestMethod.GET)
public ModelAndView welcome() {
return new ModelAndView("productsHome");
}
put the welcome-file-list in web.xml
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
in the file index.jsp , file index.jsp in the WEB-INF directory
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<% response.sendRedirect("welcome"); %>
change the servlet-mapping
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
make sure that productsHome.jsp is in the /WEB-INF/views/ directory

The problem is with the servlet mapping.
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>

Spring #Value Annotation Not Resolving

I realize this question has been asked countless times, but none of the solutions appear to be working for my situation.
I have a basic Spring-WS app I'm putting together with a single servlet context. I can see that both the #Component annotated class and the properties file are both getting picked up on startup as shown by the logs below. However, my #Value annotated String is coming back as null.
Does anyone see anything wrong with the way I've set this up? Please feel free to ask for any additional information I may have left out.
Going forward, what are the best methods I can use to investigate issues like this I encounter in the future?

You aren't using a Spring managed bean. You are creating an object yourself.
MailServerUserController userController = new TelnetMailServerUserController();
In this case, Spring is not involved in processing the #Value annotated field (or anything else for that matter).
Instead, get the bean from the context, inject it.
#Autowired
private MailServerUserController userController;
