I want to call servlet when radio button is clicked, how can I make it?

EDIT

I tried to add URL to servlet in javascript function like this

$.post( "ParentManagementServlet", "isActivated");

and like this

 $.post(<%=getServletContext().getContextPath()+"/ParentManagementServlet"%>, "isActivated");

and like this 

  $.post("/ParentManagementServlet?isActivated=true");

but both does not call servlet!

here’s the url mapping of the servlet in web.xml

<servlet>
    <servlet-name>ParentManagementServlet</servlet-name>
    <servlet-class>ps.iugaza.onlineinfosys.servlets.ParentManagementServlet</servlet-class>
</servlet>
 <servlet-mapping>
    <servlet-name>ParentManagementServlet</servlet-name>
    <url-pattern>/ParentManagementServlet</url-pattern>
</servlet-mapping>

I usually add the servlet through its name, but I read that it’s better to get the servlet absolute path form servlet context.

    As per the comments:

    about fireBug, here’s what returns $ is not defined

    The $ is definied by jQuery. You’ve apparently not declared it in your page. jQuery is a JS library and not something already builtin the browser or something.

    Put the following line before any other <script> in your <head>

    <script src="http://code.jquery.com/jquery-latest.min.js"></script>

    (you can of course also download and serve a copy from your own domain)

    <script src="jquery-1.5.2.min.js"></script>
