I have the following problem when trying to use the login.jsp
I have the following code in the login
<%# include file="/jsp/include.jsp"%>
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<script>
function sendForm() {
document.formLogin.submit();
}
</script>

<body>
<div class="container">
<form class="bs-docs-example form-horizontal"
action="ServletValidation" name="formLogin" id="formLogin"
method="post">

<div class="control-group">

<button class="btn" type="submit" action="sendForm();">Sign

</div>
</div>
</form>
</div>
</body>
</html>
And the following text in the web.xml
<servlet>
<description></description>
<display-name>ValidationServlet</display-name>
<servlet-name>ValidationServlet</servlet-name>
<servlet-class>bt.servlet.ValidationServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ValidationServlet</servlet-name>
<url-pattern>/ValidationServlet</url-pattern>
</servlet-mapping>
But once I click the button for submit it returns:
State HTTP 404 - /bt/jsp/ServletValidation
Description The resource required (/bt/jsp/ServletValidation) is not
available.
The folder structure is the following:
+bt
-src
-WebContent
-jsp
-resources
-WEB-INF
-classes
*web.xml
*index.jsp
The problem I'm finding is why is it sending to that URL
There are two problems:
Your servlet maps to the URL /ValidationServlet and your form has the action set to ServletValidation.
Maybe your login.jsp isn't at the same level of your servlet mapping.
The best solution would be setting the action of your form to map the full URL that maps to your servlet. This can be achieved using Request#getContextPath():
<form action="${request.contextPath}/ValidationServlet" ...>
<!-- content... -->
</form>
If you don't use JSTL in your project, then do it. You should avoid scriptlets in your jsp (those <% ... %> tags that hold nasty Java code inside the JSP). But if you don't, then you should try the following:
<form action="<%=request.getContextPath()%>/ValidationServlet" ...>
<!-- content... -->
</form>
Still, the first way is the best to go.
More info:

Our JSTL wiki page
Just change the web.xml file
<url-pattern>/ServletValidation</url-pattern>
ServletValidation is different from ValidationServlet.

It was working fine but suddenly its now working for ${message} and others as ${param.someName}
this is my .java class
#PostMapping("/validate")
//All the libraries are also imported and no error in code
String validateLogin(String mail,String password,String location,HttpSession session,HttpServletRequest req,Model model) {
User user;
//user=urepo.findByEmail(mail);
user=urepo.findByEmailAndPassword(mail,password);
if(user!=null)
{
req.getSession();
session.setAttribute("userid", user);
System.out.println(location);
System.out.println(user.getFname());
return "redirect:/"+location;//+"?session=userid";
}
model.addAttribute("message", "please check the username/password");
//req.setAttribute("message", "Please check the username or password");
return "redirect:login?location="+location;
}
below is my .jsp login form when I'm entering wrong password on the jsp page I want to display the message which is written in the above java file but its not displaying the ${message} and also not working with the ${param.email} too but login is working fine

Okay, I'm new to JSP and I'm trying to create a simple form with button in a JSP file index.jsp and link it to bootstrap. I just can't figure out how to call the bootstrap files from JSP. Here is my JSP code:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<link href=”Bootstrap/css/bootstrap.min.css” rel=”stylesheet” type=”text/css” />
<script type=”text/javascript” src=”Bootstrap/js/bootstrap.min.js”></script>
<title>Bootstrap Project</title>
</head>
<body>
<div class=”container”>
<form role=”form”>
<div class=”form-group”>
<label for=”exampleInputEmail1″>Email address</label>
<input type=”email” class=”form-control” id=”exampleInputEmail1″ placeholder=”Enter email”>
</div>
<div class=”form-group”>
<label for=”exampleInputPassword1″>Password</label>
<input type=”password” class=”form-control” id=”exampleInputPassword1″ placeholder=”Password”>
</div>
<div class=”form-group”>
<label for=”exampleInputFile”>File input</label>
<input type=”file” id=”exampleInputFile”>
<p class=”help-block”>Example block-level help text here.</p>
</div>
<div class=”checkbox”>
<label>
<input type=”checkbox”> Check me out
</label>
</div>
<button type=”submit” class=”btn btn-default”>Submit</button>
</form>
</div>
</body>
</html>
And here is my folder arrangement:
I'm using Eclipse IDE and Tomcat as the server. Where am I going wrong?
Thanks.
I am trying to print form validation next to each field. My jsp file looks like
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%# page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<style>
.error {
color: red; font-weight: bold;
}
</style>
<title>
FORM
</title>
</head>
<body>
<div id="wrap" >
<div class= "container" style="min-height:400px;">
<hr>
<form:errors path="applicant.applicant_email" cssClass="error"/>
<form:form method = "post" action = "${pageContext.request.contextPath}/addApplicant" modelAttribute = "applicant">
<form:errors path="applicant.applicant_email" cssClass="error"/>
<div class="form-group col-lg-4 col-md-4 col-sm-6">
<label>Email</label>
<input name = "applicant_email" class="form-control" id="inputEmail" placeholder="Email">
</div>
<div class="form-group col-lg-4 col-md-4 col-sm-6 ">
<input type = "submit" />
</div>
</form:form>
</div>
</div>
<!-- div Wrap ka End -->
<hr>
<br>
<br>
</body>
</html>
"Applicant" is the name of my model class.
Now it prints fine outside the form, but prints nothing if form:errors is used inside form:form tag. What am I missing. Any help is highly appreciated. Thank you.
I figured put what the problem was. All had to do was add path attributes to the input fields. Like in my example:
<input name = "applicant_email" class="form-control" id="inputEmail" placeholder="Email" path = "applicant_email">
In my website, I download a full webpage from another site, modify something and extract it as a string. Now, I want to display it as a part of my .jsp page, with scrolling bar.
How can I do that? It shows me error when I try to put another <html> tag.
Thanks for your help.
EDIT!!!
Here is my .jsp
<%#page contentType="text/html" pageEncoding="UTF-8"%>
<%#taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<c:if test="${not empty requestScope.website}">
<div>

</div>
</c:if>
</body>
</html>
requestScope.website is a full html page as a string, return from server. When I run, everything in the requestScope.website (such as background image) apply to all my page. I want to limit it to a part of my page, just like using iframe.
I think u can use the <jsp:include ...>tag.
Put the whole source code into a jsp and use the tag to include to your page.
Something like
<jsp:include page="mypagepath/page.jsp"></jsp:include>
I have two JSP pages. In first page I have given fields to fill personal details and I have written request.getRequestDispatcher("second.jsp") and forwarded the the request. But When I run the "first.jsp" on server in eclipse, it is directly going to "second.jsp" but in URL it is shopwing "first.jsp". What might be the problem?

You need to do response.sendRedirect() to make the effect in url.
request#forward
Silently passes the control to your another resource,And happens on server side,browser doesn't know about it.
Forward():
For a RequestDispatcher obtained via getRequestDispatcher(), the ServletRequest object has its path elements and parameters adjusted to match the path of the target resource.
sendRedirect()
Sends a temporary redirect response to the client using the specified redirect location URL and clears the buffer.
Highlighting Luggis comment,that move your business logic to Controller and try to avoid scriplets too if possible.
Though,it is not recommended,If you want to change the URL and still want to access the data in second page,one possibility is that put data in session and access in second jsp.
The problem is generated because you have a direct call of forward method in a scriptlet, this might look like this
request.getRequestDispatcher("second.jsp").forward(request, response);
By your question edit, this is generating the problem:
response.sendRedirect("academic.jsp");
Note that using scriptlets is highly discouraged.
Make sure all your data processing and navigation is handled in a Servlet or another controller classes provided by a MVC framework like JSF managed beans or Spring MVC #Controller decorated classes.
More info:
How to avoid Java code in JSP files?
StackOverflow's Servlet wiki, here you can find a real world basic example about how to handle data processing and manipulation from a view to a servlet and then navigating to another view.
The actual problem lies in first.jsp line response.sendRedirect("academic.jsp"); which is inside a JSP Declaration and not JSP Scriptlet, as per the doc variables and methods in JSP declarations become declarations in the JSP page’s servlet class which explains why when you hit the first.jsp its getting redirected to another page without any action and as other suggested its not advisable to use JSP scriptlets, or declarations in your JSP.
