java - call servlet when radio button is clicked -


i want call servlet when radio button clicked, how can make it?

edit

i tried add url servlet in javascript function this

$.post( "parentmanagementservlet", "isactivated");

and this

 $.post(<%=getservletcontext().getcontextpath()+"/parentmanagementservlet"%>, "isactivated");

and 

  $.post("/parentmanagementservlet?isactivated=true");

but both not call servlet!

here's url mapping of 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 add servlet through name, read it's better servlet absolute path form servlet context.

as per comments:

about firebug, here's returns $ not defined

the $ definied jquery. you've apparently not declared in page. jquery js library , not builtin browser or something.

put following line before other <script> in <head>

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

(you can of course download , serve copy own domain)

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