Ajax post is unable to find the URL, which leads to java class, with annotations. Gives error 404

Question

I have written my ajax post in my Java Script file like this: Where obj1 is a Stringified JSON object.

$.ajax({
    url:'./rest/input/post',
    type: 'POST',
    data:obj1,
    contentType: 'application/json',
    dataType:'json',
    success:function(data)
    {
        var values = JSON.stringify(data);
        alert(values);
    },
},'json');

I am passing it to a Java class which is as below:

@Path("/input")
public class InputResponse {
@POST
@Path("/post")
@Consumes(MediaType.APPLICATION_JSON) 
@Produces(MediaType.APPLICATION_JSON)
     public Input postInputRecord(Input obj){
         return obj;
     }
}

My Web.xml file is as below:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

</servlet>
<servlet-mapping>
<servlet-name>Jersey Web Application</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>

This is the maven project: I am running it on a Jetty Server, while invoking a url "http://localhost:8001/project_name/rest/input/post" But it is giving me 404 error. There is no error in console except this. Why is it so? How can I solve this? Any suggestion much appreciated.

Look at your path variable in the Java class. /input translates as http://localhost:8001/input/post which may not be what you want.

You are also re-declaring the @Path variable twice in your Java file. Once before the InputResponse class definition and again inside the InputResponse class itself.

And also look at your ajax call's url value. Single dot slash is the working directory. Here's a link that explains path differences between ./ and ../ http://stackoverflow.com/questions/7591240/what-does-dot-slash-refer-to-in-terms-of-an-html-file-path-location – lawrence thorne Sep 16 '15 at 04:56

See at my web.xml, I have given url-pattern as /rest/*, and the same thing as a whole is working fine for me with a GET ajax request.@lawrence thorne – tpsaitwal Sep 16 '15 at 05:19
