spring form tags uri cannot be resolved in web.xml or jars deployed with this application

spring form tags uri cannot be resolved in web.xml or jars deployed with this application - spring

I am working on java web project (maven) and used spring. Everything worked fine with spring, till I used spring form tags. While running jsp, error pops,
org.apache.jasper.JasperException: The absolute uri: [http://www.springframework.org/tags/form] cannot be resolved in either web.xml or the jar files deployed with this application
I am giving code from files as follows:

Spring validation annotations (#Size, #NotEmpty, #Max...) not working in my MVC project

I'm trying to get my head around an MVC project. There is a form page that the user fills out and they end up in an object of the Employee class.
#RequestMapping("/ask")
public String askDetails(Model model) {
model.addAttribute("employee", new Employee());
return "ask-page";
}
Here is what the class part looks like. It can be seen that I set parameter validation above some of the fields.
import jakarta.validation.constraints.*;
...
public class Employee {
#Size(min = 2, message = "Name must be min 2 symbols")
private String name;
#NotBlank(message = "surname is required field")
private String surname;
#Max(value = 100,message = "max is required field")
private int salary;
....
}
Here's what the html page looks like with the form filled out. It can be seen that the form "errors" is used to catch errors.
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
...
<form:form action="show" modelAttribute="employee">
Name <form:input path="name"/>
<form:errors path="name" />
<br>
<br>
Surname <form:input path="surname"/>
<form:errors path="surname"/>
<br>
<br>
Salary <form:input path="salary"/>
<form:errors path="salary" />
...
Well, this is how the method looks like, which redirects to another page if all the fields in the form have been validated.
#RequestMapping("/show")
public String showDetails(#Valid #ModelAttribute("employee") Employee emp, BindingResult bindingResult) {
System.out.println("surname length = " + emp.getSurname().length());
System.out.println("name length = " + emp.getName().length());
System.out.println("bindingResult.hasErrors() = " + bindingResult.hasErrors());
if (bindingResult.hasErrors()) {
return "ask-page";
} else {
return "show-page";
}
The problem is that the annotations specified above the fields in the class do not work. Here is the output of the showDetails method, which shows that data is being entered that does not match the specified restrictions in the Size, Name annotations. You can also see that bindingResult indicates no errors.
...
surname length = 0
name length = 0
bindingResult.hasErrors() = false
Does anyone know why these annotations don't work?
In my view, validation should not pass and the user should be returned the original form with an error on incorrectly filled fields
UPD.

I get a 404 error when trying to access a .jsp file under my WEB-INF directory and I can't figure out why

I've looked at every post I could find on the this issue but every time I do it seems like my configurations are as they should be.
When I type in the URL http:/localhost:8080/ I get the correct index.jsp displayed, but when I type in http:/localhost:8080/account I get the 404 error.
Any advice would be greatly appreciated!

You have added #RequestMapping("/account")
public class AccountController {
above your controller class, Therefore your controller will only map requests with /accounts header only,
As you have added #RequestMapping(value = "/account", method = RequestMethod.GET) in your method also, the controller will be looking for a accounts/accounts/ requests to execute the particular method.
Try http:/localhost:8080/account/account
or remove the class level request mapping.

JSP EL not finding requestScope variable?

So, I'm trying to learn some Spring MVC and the first tutorial I try has a model.addAttribute("printme", "From spring"); and in the JSP a ${printme}.
My controller is simple:
#RequestMapping(value = "index", method = RequestMethod.GET)
public String index(Model modelMap) {
System.out.println("on method");
modelMap.addAttribute("printme", "Hello Spring FROM INDEX !!");
return "index";
}
When I run the code it doesn't work, so I started adding to the JSP.
I wound up with this in the body:
<h1>
${param.printme}
<br />
${printme}
<br />
${requestScope.printme}
<br />
<%=request.getParameter("printme")%>
<br />
<%=request.getAttribute("printme")%>
<br />
<%=pageContext.findAttribute("printme")%>
</h1>
and my output source looks like this:
<h1>
<br />
<br />
Hello Spring FROM INDEX !!
<br />
null
<br />
Hello Spring FROM INDEX !!
<br />
Hello Spring FROM INDEX !!
</h1>
I expected param.printme to me empty string, as well as null from request.getParameter().
Shouldn't ${printme} search requestScope and find it?
Shouldn't ${printme} be the same as
${requestScope.printme}
<%=requestScope.getAttribute("printme")%>, and
<%=pageContext.findAttribute("printme")%>?
What's going on here, why isn't ${printme} finding the attribute?
I know I can just keep using ${requestScope.printme}, but it's more verbose, and I want to know why it's acting the way it is.
In case it matters I'm using Tomcat7.0.52, Spring 4.0 xsds, and java ee 3.0 xsds.

And when I visit localhost:8080 I will see the text

just fine..
Please compare your project with this one, provide additional code and ask further if required.

It looks to me like you don't have jstl referenced in the top of your jsp files. The dollar sign is jstl shorthand. Make sure you have the following in the top of your jsp files.
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

spring2 annotation has not rendered

I am new to startup a Java with Spring 2.5.5 project. But have some problem that the Spring annotation has not been resolved. I means my JSP shows the spring annotation directly, like this:

To access the controller, use this URL:

Finally, output on web browser like this:
Hello World!!!
${msg}
As you see, ${msg} is not rendered. What's wrong?
Thank you very much.

After my investigation, I should correct my question to: "Spring 2.5.6 EL has not been resolved".
And now I know that I can add this statement on every pages those has EL expression inside:
<%# page isELIgnored="false" %>
Yes it can solve my problem. But I don't want to add this statement in too many pages in my project.
I find that it is caused by isELIgnored is default to "true" if web.xml is equal or lower than version 2.3. So that I need to add this code to set isELIgnored to true globally:
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
</jsp-property-group>
</jsp-config>
But no luck. The EL is still hasn't been resolved.
Someone can help?
Thanks a lot.

Spring MVC and JSP - can not pass data from controller to jsp

I have a GWT Application with Spring MVC support. I've defined a spring controller:
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class IndexController {
#RequestMapping("/")
public ModelAndView index(HttpServletRequest request) {
ModelAndView result = new ModelAndView("index");
result.addObject("message", "hello, world!");
return result;
}
}
and this controller returns simple jsp-based view:
<%#page pageEncoding="UTF-8"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Они с нами</title>
<link href="<%=getServletContext().getContextPath()%>/style/reset.css" rel="stylesheet" type="text/css"></link>
<link href="<%=getServletContext().getContextPath()%>/style/index.css" rel="stylesheet" type="text/css"></link>
<link href="<%=getServletContext().getContextPath()%>/style/common.css" rel="stylesheet" type="text/css"></link>
<script type="text/javascript" language="javascript" src="<%=getServletContext().getContextPath()%>/stub/stub.nocache.js"></script>
</head>
<body>
<p style="display:none">${message}</p>
</body>
</html>
URL mapping and redirecting to the view works OK, but,
<p style="display:none">${message}</p>
does not works - it just prints ${message}
Here is my web.xml:
<web-app>
<!-- Reads request input using UTF-8 encoding -->

A spent all day in the searching of solution, but it still does not work. Help me please.
Thank you

You are correct, since you are defining expressions
${Anything between this is expression}
You need to include
<%#page isELIgnored="false" %>
isELIgnored is false, i.e Expressions are taken into account.

The solution is found:
it is needed to add following lines:
<%#page contentType="text/html;charset=UTF-8" language="java" %>
<%#page isELIgnored="false" %>
At the begin of the JSP file
