[SOLVED] Pass JSON object to Java Class without the use of a servlet

Pass JSON object to Java Class without the use of a servlet

I have a form in an HTML, the values for which I am obtaining using JavaScript. I am converting it to an object as the following ( in JavaScript only):

var obj = {
            LogReference:logrefgenerator(),
            ReferenceNumber : ""
}

Now, I wish to send this object using Ajax(or any other for that matter) to a Java Class (NOT A SERVLET) which I have. I am trying to do this by :

    $.ajax({
    url: 'Resource',
    type: 'POST',                                                      
    dataType :'json',
    data: obj1,
    success: function(result) {
        alert('SUCCESS');
    },
    error: function(){
        alert('Error');
}});

But the code above somehow does not seem to be working. The F12 debugger(Browser's Debugging Tool) says : Error 404: Resource not found.

Any suggestions why this wont work? I wish to send the object from my JavaScript and receive it in my Java Code for further processing. Also, Please note that I am using IE.

EDIT: following is my Resource.java:

    public class Resource extends HttpServlet {

    private static final long serialVersionUID = 1L;

    public Resource(String obj1) {
        // TODO Auto-generated constructor stub
        System.out.println(obj1);
        System.out.println("inside resource!");
    }
}

Solution

Your 404 indicates that the server cannot match a resource at the request URL. You say you do not wish to use a Servlet but are trying to POST to one.

Your URL should be something like /logHandler/. In whatever Java web framework you are using you would then map the servlet (or some other handler) to that URL. You cannot address a class directly from the client basically.
