I know about Apache Tiles in Spring, it seem working same jsp:include, but it doesn't solve my problem:
I want a file with name is layout1.jsp, in this file, I will define a layout like:
<html>
<head>
<style href="style1.css" />
</head>
<body>
<div class="main">
<div class="left">
<ul>
<li>
<li>
<li>
</ul>
</div>
<div class="content">
<h1>${message }</h1>
</div>
<div class="footer">
<span>This is footer</span>
</div>
</div>
</body>
</html>
And a file is layout2.jsp:
<html>
<head>
<style href="style2.css" />
</head>
<body>
<div class="main">
<div class="left2">
<ul>
<li>
<li>
<li>
</ul>
</div>
<div class="content2">
<h1>${message }</h1>
</div>
<div class="footer2">
<span>This is footer</span>
</div>
</div>
</body>
</html>
When user chose layout name on combobox, controller will set layout dynamic before render layout.
How should I do?
For switching the css file an you could use the Spring Theme Resolver. And you can use the same mechanism to change some small parts of your html (like the div classes)
<%# taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<html>
<head>
<style href="<spring:theme code='styleSheet'/>" />
</head>
<body>
...
<div class="<spring:theme code='contentClass'/>">
<h1>${message }</h1>
</div>
...
</body>
</html>
(But I would recommend to use the same html with same classes and just switch the css).
Do not forget to setup the theme resolver!
#See Spring Reference: Chapter Using themes
I found a method to solve this problem:
My application separator to multi module, example "Admin", "Default", each module have a interceptor, example a module interceptor:
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
String servletPath = request.getServletPath();
if (!servletPath.equals("/") && servletPath.substring(servletPath.length() - 1).equals("/")) {
response.sendRedirect(request.getContextPath() + servletPath.replaceAll("\\/+$", ""));
return false;
}
return true;
}
In view I have a class InternalResourceViewResolver.java:
package view;
import helper.AppHelper;
import java.util.Locale;
import org.springframework.web.servlet.View;
public class InternalResourceViewResolver extends
org.springframework.web.servlet.view.InternalResourceViewResolver {
public View resolveViewName(String viewName, Locale locale)
throws Exception {
AppHelper.setPage("../" + AppHelper.getModule() + "/" + viewName + ".jsp");
return super.resolveViewName("layout/" + AppHelper.getLayout(), locale);
}
}
AppHelper class:
package helper;
public class AppHelper {
private static String module = "default";
private static String layout = "main";
private static String page = "index";
public static String getModule() {
return module;
}
public static void setModule(String module) {
AppHelper.module = module;
}
public static String getLayout() {
return layout;
}
public static void setLayout(String layout) {
AppHelper.layout = layout;
}
public static String getPage() {
return page;
}
public static void setPage(String page) {
AppHelper.page = page;
}
}
In other module, example for Admin:
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
System.out.println("ServletPath" + request.getServletPath());
AppHelper.setModule("admin");
AppHelper.setLayout("admin");
return true;
}
And my view page:
In layout:
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%#taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!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=UTF-8">
<link href="<c:url value="/resources/css/main.css" />" rel="stylesheet">
<title>Welcome to web</title>
</head>
<body>
<div class="wrapper">
<div class="main">
<div class="header"></div>
<div class="content">
<div class="content-left">
<jsp:include page="<%=helper.AppHelper.getPage() %>"></jsp:include>
</div>
<div class="content-right"></div>
</div>
<div class="footer"></div>
</div>
</div>
</body>
</html>
Placeholder page:
<%#taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<h1>${message }</h1>
<h2>${welcome }</h2>
<c:forEach items="${batches }" var="batch">
${batch.id } - ${batch.name }
</c:forEach>
Here directory struct:
- src\main\webapp\WEB-INF\pages
- admin
- index
- index.jsp
- setting.jsp
- product
- index.jsp
- detail.jsp
- other
...
- default
- index
- index.jsp
- contact.jsp
- product
...
- layout
admin.jsp
main.jsp
You could do this using Tiles too ...
use apache-tiles 2.2.1 or above
In application's tiles.xml where you put layout models do this
<definition name="masterTile" templateExpression="${requestScope.layout} >
<put-attribute name="title" value="" />
<put-attribute name="header" value="/view/header.jsp" />
<put-attribute name="menu" value="/view/menu"/>
<put-attribute name="body" value="" />
<put-attribute name="footer" value="/view/footer.jsp"/>
</definition>

I have a problem with checkbox. I have such jsp page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>All Photos</title>
</head>
<body>
<form action="/photos/deletePhotos">
<c:forEach var="photo" items="${photoList}">
<p><input type="checkbox" name="id" value="${photo.key}">${photo.key}</p>
<img src="/photos/photo/${photo.key}" width="300" height="200">
<br/><br/>
</c:forEach>
<input type="submit" value="Delete" />
</form>
</body>
</html>
and such controller:
#RequestMapping("/deletePhotos")
public ModelAndView deleteSomePhotos(#PathVariable(name = "id", required = false) long[] id) {
System.out.println(id);
return new ModelAndView("all", "photoList", photos);
}
problem is id==null, no matter checked checkbox or not. Where is my mistake?
#PathVariable is for path variable, like #RuquestMapping("/deletePhotos/{id}").
Use #RequestParam instead of #PathVariable.
Refer here : #RequestParam vs #PathVariable
I am newbie in spring mvc. I am trying to make simple crud in spring using MySQL jdbc. For datamapping I have used spring form. Whenever I try to use spring form it shows an Error
Error is here
Whenever i remove spring form and use normal form it looks ok but shows an error when used spring form. The error says java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'userData' available as request attribute

You have to Use #RequestParam to get single value.
To Bind form data with model class You need to create Model(POJO) as userData commandName="userData".CommandName and ModelClass Name both same.
Fields of class firstName and both same. Then Your Form Data Bind with Pojo It will come at your controller Class.
I hope it will help.
I have a controller method as follow.
#RequestMapping("/edit/{jobId}")
public String editJob(#PathVariable("jobId") Integer jobId,Model model){
model.addAttribute("id",jobId);
return "edit";
}
in which i am passing the jobId to get the instance of the job by id and returning "edit" string so that it maps to edit.jsp as per the InternalResourceViewResolver. But when i click on the link it goes to /edit/44 in which case 44 would be the id of the job for which the edit link belongs to. Finally i got the error stating no resource found.

In editJob method your are returning only id of job with model attribute to edit.jsp. But actually on edit.jsp page you need job object so you need to get job object by id add it as model attribute.
#RequestMapping("/edit/{jobId}")
public String editJob(#PathVariable("jobId") Integer jobId,Model model){
//model.addAttribute("id",jobId); this is wrong
Job job = jobService.getJobById(jobId);
//write method in jobservice to get job by id i.e. getJobById(Integer jobId);
model.addAttribute("job",job)
return "edit";
}
In my web application, I have a home page where the options available to the user are placed in a fixed sidebar in the top of the screen, and each one of this options are opened inside of a tag <div> in this same page.
My problem is: when this content is a form, and I submit it to the server, after the processing, the output page isn't opened in this <div>, but in the entire navigation space. What I want is a way of capture this return and display it in the same <div> it was originated.
the code for my home page is:

}
Someone have any thoughts about how to do that?
Well, spring mvc just open new page with a content you set in ModelAndView. If you want to load somthing just in some part of page ( in this case ) there pure javascript / jquery ajax is needed. So steps needed here:
Add javascript which will do ajax request to controller
Controller need to return JSON ( #ResponseBody can help you )
You have to do some DOM manipulation using javascript/jquery to put JSON answer to your div.
I am uploading a file in a form, that form also contains some textfields I enter some values in the textfields. I want this value to remain when I click upload button. And there is also a save button, when I click this button uploaded file should get saved in database. Can any one help me out?
JSP file is here:
<body>
<form action="./upload" enctype="multipart/form-data" >ID: <input type="text" name="id" value="" />Name: <input type="text" name="name" value="" />
<input name="uploaded" type="file" />
<input name="save" type="submit" value="Upload" />
<input type="submit" value="save1" name="save" /></form>
</body>
I need the bussiness logic in a servlet..
Your options are:
Persist the data to your back-end and re-populate the form
Persist the data to the the in-browser Storage (http://www.w3schools.com/html/html5_webstorage.asp)
Put the upload form in an IFRAME
The easiest option is the IFRAME.
Hey you are saying the text field values should be there while clicking Upload button. You don't have to do this thing. By default it will be there. You should it will venish man? Please mention your exact requirement.
See there is no provision to keep the file field data using value attribute.
