Ajax call to wcf is returning undefined

I'm trying to call a function exposed by WCF service using ajax but the success method is always returning 'undefined' even though the function itself on the WCF side is returning the right answer
I tried debugging and printing everything and the WCF is returning the right answer but when the ajax call enters the success method object it receives is undefined

Not sure why you meet this problem , I have copied your code and have a test, but I could get the response.
Below is my code.
[ServiceContract]
public class MyTestRestService
{
[OperationContract]
[WebInvoke(
Method = "POST",
BodyStyle = WebMessageBodyStyle.WrappedRequest,
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json
)]
public Result_Login LoginAdmin(string email, string password)
{
Result_Login resultLogin = new Result_Login();
resultLogin.ExceptionMsg = "exception";
resultLogin.login = true;
return resultLogin;
}
}
Model
public partial class Action_Result
{
public string ExceptionMsg { get; set; }
public Action_Result()
{
this.ExceptionMsg = string.Empty;
}
}
public partial class Result_Login : Action_Result
{
public bool login { get; set; }
}
Endpoint config.
<service name="Service.Rest.MyTestRestService" >
<endpoint binding="webHttpBinding" contract="Service.Rest.MyTestRestService" behaviorConfiguration="web"></endpoint>
</service>
To enable cross origin request, if your wcf rest server and your client are not at the same origin.
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS" />
<add name="Access-Control-Allow-Headers" value="*"/>
</customHeaders>
</httpProtocol>
protected void Application_EndRequest(object sender, EventArgs e)
{
if(HttpContext.Current.Request.HttpMethod == "OPTIONS")
{
HttpContext.Current.Response.StatusCode = 200;
}
}
The result.

It worked after adding
<webHttp defaultOutgoingResponseFormat="Json" />
to the service behavior in web.config

What's the true purpose of setJavaScriptCanOpenWindowsAutomatically

According to Android document:
Tells JavaScript to open windows automatically. This applies to the JavaScript function window.open(). The default is false.
But I didn't see any different between use or not use this API in my code, window.open works fine in the both cases, so what's the true purpose of this API or my usage is not correct?
My code sample as below:
public class MainActivity extends Activity {
private WebView mWebView;
//private Context mContext
RelativeLayout mParent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mParent = new RelativeLayout(MainActivity.this);
setContentView(mParent);
mWebView = new WebView(MainActivity.this);
WebSettings settings = mWebView.getSettings();
settings.setSupportMultipleWindows(true);
settings.setJavaScriptCanOpenWindowsAutomatically(false);
settings.setJavaScriptEnabled(true);
mParent.addView(mWebView);
mWebView.loadUrl("file:///android_asset/create_window.html");
mWebView.setWebViewClient(new MyWebViewClient());
mWebView.setWebChromeClient(new WebChromeClient() {
#Override
public boolean onCreateWindow(WebView view, boolean dialog, boolean userGesture, Message resultMsg) {
WebView newWebView = new WebView(view.getContext());
newWebView.getSettings().setUserAgentString("BBB");
//newWebView.getSettings().setJavaScriptEnabled(true);
//newWebView.setWebChromeClient(this);
newWebView.setWebViewClient(new MyWebViewClient());
//view.getSettings().setUserAgentString("CCC");
mParent.addView(newWebView);
WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(newWebView);
resultMsg.sendToTarget();
return true;
}
#Override
public void onCloseWindow(WebView window) {
mParent.removeViewAt(mParent.getChildCount() - 1);
}
});
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, final String url) {
super.onPageFinished(view, url);
}
}
}
The content of create_window.html as below:
<html>
<!-- scripts -->
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Create Window</title>
<script>

It's possible by using Struts2, jsp without javascript/jquery? if not how can I add jquery code in Struts2?

Implementing Ajax in spring MVC

Ajax is not sending the data to the specified URL. Here is my controller:
#Controller
public class HomeController {
private List<User> userList = new ArrayList<User>();
#RequestMapping(value = "AddUsers.htm", method = RequestMethod.GET)
public String showForm() {
return "AddUsers";
}
#RequestMapping(value = "User.htm", method = RequestMethod.POST)
public #ResponseBody
String addUser(#ModelAttribute(value = "user") User user,
BindingResult result) {
String returnText;
if (!result.hasErrors()) {
userList.add(user);
returnText = "User has been added to the list. Total number of users are"
+ userList.size();
} else {
returnText = "Sorry, an error has occur. User has not been added to list.";
}
return returnText;
}
#RequestMapping(value = "ShowUsers.htm")
public String showUsers(ModelMap model) {
model.addAttribute("Users", userList);
return "ShowUsers";
}
}
AddUser.jsp page
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<script src="/AjaxWithSpringMVC2Annotations/js/jquery.js"></script>
<script type="text/javascript">
function AjaxCall() {
alert('ready');
//get the form variables....
var name = $('#name').val();
var education = $('#education').val();
$.ajax({
type: "POST",
url: "AddUsers.htm",
data: " name=" + name + "&education=" + education,
success: function (response) {
$('#info').html(response);
$('#name').val('');
$('#education').val('');
},
error: function (e) {
alert('ERROR : ' + e);
}
});
}
</script>
<body>
<h1>Welcome to the AddUsers page. </h1>
<table>
<tr><td>Enter your name : </td><td> <input type = "text" id="name"></td></tr>
<tr><td>Educational qualification : </td><td> <input type = "text" id="education"></td></tr>
<tr><td colspan = "2"><input type="button" value="Add Users" onclick="AjaxCall()"></td></tr>
<tr><td colspan = "2"><div id ="info"></div></td></tr>
</table>
Show users
</body>
</html>
I have inserted an alert within the ajax which never comes up. So I believe there is something wrong with the ajax method.

}

I corrected the upper case problem ($.ajax instead of $.Ajax). Thanks for pointing out.
Now I have a different error:
POST http://localhost:8080/sum/AddUsers.htm 405 (Method Not Allowed)

change url:"AddUsers.htm" to url: "${pageContext. request. contextPath}/AddUsers.htm" and try.

the url you are calling is this
type: "POST",
url: "AddUsers.htm",
Which is POST, the controller method is GET. Hecne the 405 error, method not supported.

You try to send POST request but mapped your method call with GET method
#RequestMapping(value = "AddUsers.htm", method = RequestMethod.GET)
try to change RequestMethod.GET to POST

Datalist Delete Command Event implementation using Page Methods

I have a DataList and Update Panel in my page. After implementation, I checked that the response is talking very long time after using Update panels...Here is the study material. I have a Delete Command event in Datalist and works find in the above mentioned case. I was trying to implement Delete Command using Page Methods. Any Idea how to do that?
I basically want to find hidden controls in this event and have to delete the record in `database. Any help will be highly appreciated.

Rest Services
The full application can be downloaded from:
http://sdrv.ms/LJJz1K
This sample uses rest services in ASP.Net (the same concepts can be applied to a MVC application)
The clearer advantage when using rest services vs page methods, is testability.
I will guide you step by step to configure the service:
You need the following references:
System.Web.ServiceModel.dll
System.Web.ServiceModel.Activation.dll
System.Web.ServiceModel.Web.dll
Nuget packages:
jQuery
jQuery plugins:
jQuery Block UI (it’s available as a single script file)
Service info
[ServiceContract]
public interface IMyService
{
[OperationContract]
[WebInvoke(
ResponseFormat = WebMessageFormat.Json,
RequestFormat = WebMessageFormat.Json,
UriTemplate = "/DeleteFromService",
Method = "DELETE")]
void Delete(int id);
}
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class MyService : IMyService
{
public void Delete(int id)
{
// delete your product
// simulate a long process
Thread.Sleep(5000);
}
}
In Global.asax
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
RouteTable.Routes.Ignore("{resource}.axd/{*pathInfo}");
RouteTable.Routes.Add(new ServiceRoute("",
new WebServiceHostFactory(),
typeof(MyService)));
}
In web.config
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<standardEndpoints>
<webHttpEndpoint>
<standardEndpoint name="" helpEnabled="true"
automaticFormatSelectionEnabled="true" />
</webHttpEndpoint>
</standardEndpoints>
</system.serviceModel>
Register scripts (they can be registered in a master page)
<script type="text/javascript" src="Scripts/jquery-1.7.2.min.js" language="javascript" ></script>
<script language="javascript" type="text/javascript" src="Scripts/jquery.blockui.1.33.js"></script>
In a ASP.Net content page (in this sample, I am using a master page)
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<input type="button" value="Delete" id="myButton" />
</asp:Content>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script type="text/javascript" language="javascript">
function deleteFromService() {
if (!confirm("Are you sure you want to delete?")) {
return;
}
$.blockUI();
$.ajax({
cache: false,
type: "DELETE",
async: true,
url: "/DeleteFromService",
data: "3", // get your id to delete
contentType: "application/json",
dataType: "json",
success: function () {
$(document).ajaxStop($.unblockUI);
alert("done");
},
error: function (xhr) {
$(document).ajaxStop($.unblockUI);
alert(xhr.responseText);
}
});
}
jQuery().ready(function () {
$("#myButton").click(deleteFromService);
});
</script>
</asp:Content>
And that’s it, ajax commands the easy way =)
