jquery - Using servlets in Struts 2 -

i wonder if using servlets in struts 2.3.4 practice or not?

i need place html in specific place in jsp without page refreshing. found 2 ways achieve this:

1.create servlet , use ajax handle post request/response, i.e. :

<div id="maindiv">  </div>  <script>     $(document).ready(function() {         $('#div2').click(function() {              $.post('testservlet', function(responsetext) {                 $('#maindiv').html(responsetext);              });         });     }); </script> 

2. call action using jquery plugin , place generated response in target place in jsp(using well-known sx:submit). problem not know how handle post request/response. jquery submit uses get method.

could please tell me solution better? in both cases have access httpservletrespone , printwriter allows writing text/html content result jsp. should use printwriter inside action class or in servlet method?

there no reason use servlet here.user simple ajax (jquery) , let action handle , send response you.

struts2 actions capable enough handle ajax request , free use post/get method per requirements.

here sample how post data action class , response there

javascript

$.ajax({     type : 'post', // can use         url : action url,      data : $(formid).serialize(),  // post     success : function(response) {          // handle server response          $("#mydiv").html(response);     },     error : function(e) {     // handle error     }   }); 

action class

public class myaction extends actionsuport{   // define getter , setter data   public string execute() throws exception{    // define logic here    return action.success;  } } 

struts.xml

<action name="myaction" class="myactionclass">    <result>jsp success</result> </action> 

jsp content send jquery code after ajax call , can paste content specified div.

also note sx:submit represents dojo tags no longer supported in struts2 , has been deprecated long back.

using servelet struts2 not bad practice provided have valid use case , there many cases being used, struts2 provide way let servlet handle request in place of actions
