Web-service call from Apache to Glassfish

Question

I have written static HTML pages which run on Apache server and I give a web-service call which is present on Glassfish server.
I want to calculate the number of rows present in the selected Excel file. For this, I make a web-service call through Ajax; where I send a file object to it, which then, reads the file and returns the number of rows present in that file.
But, I could not make an Ajax POST for a file object.
For Example, I have an HTML form containing a file object (for which I have to calculate the number of rows). I have to send this form to the web-service for processing the file.
My form is like this:
<form id="myForm" action="http://www.mydomain.com:8080/myApp/jersey/myClass/calculateRows" method="POST" enctype="multipart/form-data" accept-charset="utf-8" name="submitForm">
        input id ="workbook" name="workbook" type="hidden"/>
</form>
For this I used:
    $("#myForm").ajaxSubmit(function(noOfRows)
       alert(noOfRows);
In the web-service, I gave:
    @Path('myClass')
    public class myClass
      @POST
      @Path("calculateRows")
      public Response calculateNoOfRows(@Context HttpServletRequest request)
        int noOfRows = 0;
        String wbk = request.getParameter("workbook");
        for (Part part : request.getParts())
             if (!part.getName().equalsIgnoreCase("workbook"))
                  //code to calculate number of rows
                  noOfRows = 100;   (for example)
        ResponseBuilder builder = null;
        builder = Response.ok(String.valueOf(noOfRows));
        builder.header("Access-Control-Allow-Origin", "*");
        builder.header("Access-Control-Allow-Methods","POST");
        builder.header("Allow-Control-Allow-Headers", "Origin,Connection,Keep-Alive,Accept-Encoding,Accept-Charset,Accept,User-Agent,Host,X-Requested-With");
        return builder.build();
In the Firebug, the above given URL does not appear in the Console tab.
And, in the Net tab, I see like this:
    OPTIONS http://www.mydomain.com:8080/myApp/jersey/myClass/calculateRows
I am not able to resolve the problem. Can anyone help?

Hi,
I would recommend implementing the web-service callout logic in a custom cachestore/cacheloader (see the CacheLoader.load() method) and configure your rwbm with your cachestore implementation.
While subclassing RWBM and overriding functionality can be done, the CacheLoader interface is the intended method designed to accomplish this kind of task. RWBM internal implementations may perform other internal bookkeeping and may vary over time.
