I have a problem with sending <form> to controller. When i'm pressing submit button it shows me 400 error. And when i'm trying to output smth into console in POST method it doesn't show it. Why controller doesn't get my form? Thanx!

Here is my controller method.

public String listUsersSort(
#RequestParam(value="weight") int weight,
#RequestParam(value="gender") String gender,
#RequestParam(value="place") String place,
#RequestParam(value="age") int age,
Model model, Principal principal)
{
System.out.println("int");
if(weight<40 && gender.equals("") && place.equals("") && age<19)
{
model.addAttribute("users", new Users());
model.addAttribute("noparams", "Задайте параметры поиска");
return "searchingUser";
}
else{
model.addAttribute("users", new Users());
model.addAttribute("listUsersSort", usersService.listUsersSort(weight, gender, place, age, principal.getName()));
model.addAttribute("allUserMess", this.dialogService.allNewMessForUser(principal.getName()));
model.addAttribute("countOfFeedbacks", this.feedbackService.checkUnreadFedbacks().size());
model.addAttribute("countOfNewUsers", this.usersService.countOfNewUsers());
return "searchingUser";
}}


You're getting the error because your code is somewhere in between using the form-backing bean, or binding the parameters from request. You should either remove the
modelAttribute and path attributes from your form.
Or remove the #RequestParam annotated arguments from your request, and create a form-backing object with weight, age, place, gender properties, and add the object to the controller method signature annotated with #ModelAttribute("users")


In your JSP page, actually you are missing the Context Root while giving request to your controller.
<form:form class="form-inline centerBlock" modelAttribute="users"
method="POST" action="/app/user/search" accept-charset="utf-8">
In this case the request url will be :
http://yourHost:portNo/app/user/search
So to solve this problem you can include your context root with the action:
<form:form class="form-inline centerBlock" modelAttribute="users"
method="POST" action="/your-context-root/app/user/search" accept-charset="utf-8">
OR by writing in this way:
<spring:url value="/app/user/search" var="formUrl"/>
<form:form class="form-inline centerBlock" modelAttribute="users"
method="POST" action="${formUrl}" accept-charset="utf-8">

Some other way to display data from sql table on jsp

I have used jstl to display particular data from table named status(all columns are string type) on found.jsp. In my table I have entered 1 and 0 under status column where 1 is for IN and 0 is for OUT.
found.jsp

I don't want 1 and 0 to be shown instead i want IN and OUT to be shown under the column and I don't want to change the database table entery from 1 and 0 to IN and OUT Is there a way I can do this?

you can do it with <c:choose> tag
<c:choose>
<c:when test="${row.fstatus=='1'}">
IN
</c:when>
<c:otherwise>
OUT
</c:otherwise>
</c:choose>

<c:forEach> tag not work properly

My java code is
#RequestMapping(value = "/common_views/view-lecturer-Projects")
public String viewLecturerProjects(HttpServletRequest request, ModelMap map) {
String userId=request.getParameter("userId");
map.put("viewUserProjects", projectService.findProjectByUserId(Long.valueOf(userId)));
System.out.println("=================>Project type= "+projectService.findProjectByUserId(Long.valueOf(userId)).getTypeOfProject());
System.out.println("=================>Project title= "+projectService.findProjectByUserId(Long.valueOf(userId)).getTitleOfProject());
// System.out.println("===============>Project= "+(projectService.findProjectByUserId(Long.valueOf(userId))).get(0).getTitleOfProject());
return "common_views/viewLecturerProjects";

Write the following taglib import statement on top of your jsp.
<%# taglib prefix="c"
uri="http://java.sun.com/jsp/jstl/core" %>
and if you dont have JARSS for JSTL, then download from below URL and put that JAR into your Build Path of project.

The scenario is as follows:
I entered some values in search.jsp. I submitted the form, and accordingly some results got loaded into the mainContent <div>. Since form was submitted using Struts 2 jQuery plugin submit , the URL remains the same and hence browser back button doesn't work. If I want to go back, how can I do that.
I read about some hash technique but , I am not able to apply it to this.

In the header tag of Struts2 jQuery use ajaxhistory attribute. Setting this attribute to true enabled browser history for Ajax requests. For details see wiki of header tag.

Spring WebFlow2 Javascript only working on first radio button

Spring WebFlow2 Javascript only working on first radio button
I am trying to use Spring JavaScript that comes with WebFlow2 to submitted my page with a transition value if the user clicks on one of the radio buttons.
I inserted my javascript on the page using onclick and onchange and it only works if the first radio button is selected. I dont know why but I think I tried everything... can someone please tell me if this is a issue with Spring JavaScript.

You have:
<form:radiobutton value="B" path="row" id="rowBtn" />Row: B<BR>
<form:radiobutton value="A" path="row" id="rowBtn" />Row: A<BR>
Your two radiobuttons have the same element id.
The AjaxEventDecoration does a lookup based on that elementId. It assumes it is unique on the page and it does not expect multiple elements with the same id. You should give the second radiobutton another id.
You should probably just reenter the AjaxEventDecoration for that id as well.
If Spring.AjaxEventDecoration allows you to do something similar based on element class(instead of elementId) maybe you can do that, instead of duplicating the current Spring.AjaxEventDecoration snippet.
