How to send value from jquery to java class?

Question

This is my code in html file:

<form name="f" action="j_spring_security_check" method="post">
<input class="btn" type="button" onclick="submitForm()" value="ورود" id="submitButton" name="submitButton" disabled="disabled"/>

<input type="text" id="browser_version" name="browser_version" />
<br />
<input type="text" id="browser_type" name="browser_type"/>


 <script type="text/javascript">
    $("#submitButton").click(function() {

        var browser_version = $("#browser_version").val();
        var browser_type = $("#browser_type").val();

         alert(" browser_version   :    " + browser_version);
         alert(" browser_type   :    " + browser_type);

        $.ajax({
            type: "POST",
            url: "j_spring_security_check",
            data:'browser_version=' +encodeURIComponent(browser_version) &'browser_type=' + encodeURIComponent(browser_type),
            dataType: "json"
        }); 
    });
</script>
</form>

I used ajax jquery in this code. How to show 2 values in to java class for insert to file. For Example:

System.out.println((browser_version) or (browser_type))

If possible with an example.

Assuming j_spring_security_check refers to a Servlet, here is an example of what the code would look like in your servlet class:

public class MyServlet implements javax.servlet.Servlet
{
    public void service(javax.servlet.ServletRequest req, ServletResponse res)
         throws ServletException, java.io.IOException
    {
        String browserVersion = req.getParameter("browser_version");
        String browserType = req.getParameter("browser_type");

        // use the variables browserVersion and browserType
    }

    // other methods in the servlet
}

     "browser_version": encodeURIComponent(browser_version),

A few words about what you have posted would be nice ;-]

on servlet or SpringController, these parameters are available with httpServletRequest.getParameter("browser_version"); r
