Passing string with "+" sing from jsp to servlet

I'm passing a string, that contains plus signs (+), from jsp page to servlet, but in the servlet, the string has blank spaces instead of "+".

JSP code: 

     var data = {Certificate:"KgAwIBAgIQQ+1b5xQKgN0HfjIAPy+vdjANBg",Id:10043};
     $.ajax({
           type: "POST",
           url: "Assinatura",
           data: 'signStart=' + JSON.stringify(data)
       });

Servlet code:

request.getParameter("signStart"); //KgAwIBAgIQQ 1b5xQKgN0HfjIAPy vdjANBg

I know I could replace the spaces on server side, but was wandering if there is a better solution.

You need to encode the string while passing it to Servlet in your ajax request. You can use encodeURIComponent for that:

$.ajax({
    type: "POST",
    url: "Assinatura",
    data: 'signStart=' + encodeURIComponent(JSON.stringify(data))
});

or you can pass data as Object, instead of String:

data: {'signStart': JSON.stringify(data)}
