You can do the following in java script and run your java script function as your function run it takes control to controller ,their you can provide the jsp view or any view
<script>
function popup() {
window.open("../popup/searchspring", 'window', 'width=200,height=100');
}
</script>
and in controller you have to do something like this which will navigate your request to desired page cause in spring controller decide the navigation of view pages
#RequestMapping(value = "/searchspring", method = RequestMethod.GET)
public String view(Model model) throws Exception {
EmployeeBO employeeBO = new EmployeeBO();
model.addAttribute("employeeBO", employeeBO);
return "EmployeeForm";
}
I have solved it in my Spring MVC Project by the following way:
The Controller class is like this:
#RequestMapping(value = "viewPicture.dispatch", method = RequestMethod.GET)
public String viewPicture(HttpServletRequest request, RequestParam(value="fileName")String fileName, #RequestParam(value="filePath")String filePath) {
//some code..
return "viewDCPicture"; //the View where it will go.
}
The JSP page on which I have written JS and Html code also, is like this:
<script>
function viewDCPicture(fileName){
var filePath = $("#filePath").val();
//Setting the left and right size of the pop-up window
var left = (screen.width/2)-(1100/2);
var top = (screen.height/2)-(170/2);
$.ajax({
method: "GET",
url : "viewPicture.dispatch?fileName=" + fileName + "&filePath=" + filePath,
success : function(response) {
var strURL = "viewPicture.dispatch?fileName=" + fileName + "&filePath=" + filePath + "";
window.open(strURL, 'viewDCPicture', 'width=1100, height=600, resizable=1, scrollbars=yes, location=0, status=0, titlebar=no, toolbar=0, addressbar=0, top='+top+', left='+left+'');
},
error : function(e) {
}
});
}
</script>
<table>
<tr>
<td align="right"><label>SUPPORTING DOCS.</label></td>
<c:forEach items="${attachmentDtlList}" var="data">
<td>
${data.key}
<input type="hidden" id="filePath" value="${data.value}">
</td>
</c:forEach>
</tr>
</table>
In my template.xml where the JSP files are mapped with the perticular name = "viewDCPicture", I have made changes like this:
I have created a template inside the template.xml file as:
<definition name = "viewDocTemplate" template = "/viewDoc.jsp">
<put-attribute name = "body" value = "" />
</definition>
And used it inside the temlate.xml file as:
<definition extends = "viewDocTemplate" name = "viewDCPicture">
<put-attribute name = "body" value = "/enquiry_management/viewDCPicture.jsp" />
</definition>
The viewDoc.jsp file which will help the Pop-up window file viewDCPicture.jsp to bind it inside body of viewDoc.jsp is as follows:
<%# page language = "java" contentType = "text/html; charset = UTF-8"
pageEncoding = "UTF-8"%>
<%# taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core"%>
<%# taglib uri = "http://tiles.apache.org/tags-tiles" prefix = "tiles"%>
<%# taglib uri = "http://www.springframework.org/tags" prefix = "spring"%>
<!DOCTYPE html>
<html>
<head>
<meta charset = "UTF-8">
<title>Insert title here</title>
</head>
<body>
<%-- Adding spring attribute for adding body, header, footer etc tag. --%>
<spring:htmlEscape defaultHtmlEscape = "true" />
<tiles:insertAttribute name = "body" />
</body>
</html>
The viewDCPicture.jsp file is like this:
<html>
<head>
</head>
<table align="center" class="headingSpas">
<tr>
<td class="headingSpas">
<table width="100%" align="center" bgcolor="#CCCCCC">

<td colspan="2" align="center" class="headingSpas" >

I am new in Spring MVC and learning about #modelattribute annotation and getting above error.Everything else works fine without modelattribute annotaion. I even tried using #RequestParam instead of #modelattribute and everthing worked fine. But I am not able to understand what is wrong with the code below. Please can anyone help?

You may need to annotate your class not as #Controller but as #ControllerAdvice. A useful page providing an example of the use of #ModelAttribute-- http://www.baeldung.com/spring-mvc-and-the-modelattribute-annotation --comments:
It is also important that you annotate the respective class as
#ControllerAdvice. Thus, you can add values in Model which will be
identified as global. This actually means that for every request a
default value exists, for every method in the response part.
Perhaps you are not adding all attributes in your Student class? In any event, perhaps a default object for Student is not available since #ControllerAdvice is not being used. I hope this helps. But regardless, more useful documentation on the subject can be found on that page I referenced above.
I am working on spring mvc application, there I have a form where a user can change his password. I am validating this form by using default spring form validation (see validator code below).

ConfirmPasswordlength.match= Confirm Password should be at least 8 characters
NewPassword.invalidChars=New Password has special characters which are not allowed
ConfirmPassword.invalidChars= Confirm Password has special characters which are not allowed
You can see that when the form has errors, I am returning control back to the same JSP.
My problem is that I am unable to trace the bug/error where my spring form validation is working fine, but when I am trying to display the errors which are defined in my properties file.
You should not explicitly invoke validator. Use this validation method instead:
#Valid #ModelAttribute("forName") FormName formName,
BindingResult bindingResult, Model model,
RedirectAttributes redirectAttributes, HttpSession session
I want to show Data without passing parameter to servlet.

You are using post method in the form:
<form action="${formActionURL}" method="post" id="searchForm">
So you need to move your business logic handling searching in the servlet to the doPost() method.
In the doGet() you just leave logic forwarding to empty ManipulationPage.jsp, when user clicks the link on your Storing data page.
how to show validation error message if user has not selected any value of spring web mvc dropdown box. Not able to use #Notnull and #Notempty because I'm mapping anothor bean values using #manytoone. How to achieve this?. thanks
#Entity()
#Table(name = "QuestionType")
public class QuestionType {
#Id
#GeneratedValue
#Column(name = "id", nullable = false)
private int id;
#Column(name = "questionTypeName", length = 25, nullable = false)
#Pattern(regexp="[a-z|A-Z|\\s]+$",message = "*invalid")
#Size(max = 25, message = "*invalid")
#NotEmpty(message = "*")
private String questionTypeName;
#ManyToOne
//Here not able to use #Notnull & NotEmpty. I'm getting validator should not be used for primitive type
#JoinColumn(name = "domainid", referencedColumnName = "id", insertable = true, updatable = true)
private Domain domainId;
//getters and setters omited

Your data binding is flawed. You should be using the domainId field itself (IMHO that should be named domain instead). Use a Converter to convert to/from that object.
First change the select in your JSP.
<form:select path="domainId" items="${domainList}" itemValue="id" itemLabel="domainName" />
Then your entity should have the #NotNull on the domainId field
#ManyToOne
#JoinColumn(name = "domainid", referencedColumnName = "id", insertable = true, updatable = true)
#NotNull
private Domain domainId;
Finally you need a PropertyEditor to convert the incoming id to a actual Domain object.
public class DomainEditor extends PropertyEditorSupport {
private DomainRepository repository;
public DomainEditor(DomainRepository repository) { this.repository=repository;}
public String getAsText() {
Domain value = (Domain) getValue();
return value != null ? String.valueOf(value.getId()) : "";
}
public void setAsText(String text) {
setValue(text == null ? null : repository.findOne(Integer.valueOf(text));
}
}
You can register this in your #Controller annotated class by adding a #InitBinder annotated method.
#InitBinder
public void initBinder(WebDataBinder dataBinder) {
dataBinder.registerCustomEditor(Domain.class, new DomainEditor(this.repository);
}
A final note for this to properly work make sure that you have a proper implementation of the equals and hashcode methods in the Domain class!

In my controller there are different method i want to call them with one form action. i dont know how to map map the request to particular method with different value of submit button , as i run my index page it directly go to controller from their it can render the view from view() of my controller and as the Search .jsp is open i get the by default 0 value on my EmployeeId input field i dont know why its happening plz help me out i m new on spring
here is my controller
package com.nousinfo.tutorial.controllers;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.nousinfo.tutorial.model.EmployeeForm;
import com.nousinfo.tutorial.service.impl.EmployeeServiceImpl;
import com.nousinfo.tutorial.service.model.EmployeeBO;
#Controller
#RequestMapping("/search")
public class SearchEmployeeController {
private EmployeeServiceImpl employeeServiceImpl;
public void setEmployeeServiceImpl(EmployeeServiceImpl employeeServiceImpl) {
this.employeeServiceImpl = employeeServiceImpl;
}
#RequestMapping(value = "/searchspring", method = RequestMethod.GET)
public ModelAndView view(
#ModelAttribute("employeeForm") EmployeeForm employeeForm)
throws Exception {
ModelAndView model = new ModelAndView();
model.addObject("employeeForm", employeeForm);
model.setViewName("Search");
return model;
}
#RequestMapping(value = "/employeeNo", method = RequestMethod.POST)
public ModelAndView searchByEmpNo(
#ModelAttribute("employeeForm") EmployeeForm employeeForm)
throws Exception {
ModelAndView model = new ModelAndView();
model.addObject("employeeForm", employeeForm);
Long i = employeeForm.getEmployeeNumber();
EmployeeBO employeeBO = employeeServiceImpl.getEmployee(i);
System.out.println(employeeBO);
model.addObject("employeeBO", employeeBO);
model.setViewName("EmployeeDetail");
return model;
}
#RequestMapping(value = "/empByName", method = RequestMethod.POST)
public ModelAndView searchByEmployeeName(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {
ModelAndView model = new ModelAndView();
model.addObject("employeeForm", employeeForm);
List<EmployeeBO> employeeBOs = employeeServiceImpl
.findEmployees(employeeForm.getFirstName());
model.addObject("listEmployeeBO", employeeBOs);
model.setViewName("EmployeeList");
return model;
}
#RequestMapping(value = "/empByDeptId", method = RequestMethod.POST)
public ModelAndView searchByDeptId(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {
ModelAndView model = new ModelAndView();
model.addObject("employeeForm", employeeForm);
List<EmployeeBO> employeeBOs = employeeServiceImpl
.getAllEmployeeByDeptid(employeeForm.getDepartmentId());
model.addObject("listEmployeeBO", employeeBOs);
model.setViewName("EmployeeList");
return model;
}
}

As an alternative to configuring different endpoints for the same form based on the button clicked (using either separate forms in the HTML or changing the form action via JS), you could use the params attribute of the RequestMapping annotation to further narrow the form submission to a specific controller method based on the value of the button (or any other form submitted field). See the Spring documentation on this for more detail.
Using this strategy, your request mappings would look something like this:
#RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindByName")
public ModelAndView searchByEmployeeName(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {
...
#RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindByDeptNO")
public ModelAndView searchByDeptId(
#ModelAttribute("employeeForm") EmployeeForm employeeForm) {
...
#RequestMapping(value = "/employeeSearch", method = RequestMethod.POST, params="method=FindById")
public ModelAndView searchByEmpNo(
#ModelAttribute("employeeForm") EmployeeForm employeeForm)
throws Exception {
...
i dont know how to map map the request to particular method with different value of submit button
Have each search in a separate form. Each form mapped to different controller methods. Like this:
<form:form action="empById" method="post" commandName="searchBean">
Employee_ID
<form:input path="employeeNumber" />
<input type="submit" name="method" value="FindById" />
</form:form>
<form:form action="empByName" method="post" commandName="searchBean">
Employee_Name
<form:input path="firstName" />
<input type="submit" name="method" value="FindByName" />
</form:form>
<form:form action="empByDeptNo" method="post" commandName="searchBean">
Employee_Name
<form:input path="departmentId" />
<input type="submit" name="method" value="FindByDeptNO" />
</form:form>
Now different search requests will map to the correct controller method.
i get the by default 0 value on my EmployeeId input field i dont know why its happening
Before you add an instance of EmployeeForm to the model, initialize it to what ever default value you would like to have seen in the search page.
