Java - Spring - portlet API @Controller how to read ajax parameters -


i have following latest jquery v aajx call multiple parameters.

in java code able first parameter value rest of them found null.

$.ajax({         url : '<portlet:resourceurl id="entitledrequest"/>',         data: '<c:out value="pfx= ${account.accountnumber}-${outletui.outlet}-${count}&acc=${account.accountnumber}" />',         cache: false,         success : function(result) {              //targetelem.html(result); update ui          }     });

following java code first parameter not null after params null, have debug http request parameters present in request object clue whats wrong here ?

controller("ajaxrequestcontroller") @requestmapping(value = "view") public class ajaxrequestcontroller implements portletconfigaware  {   @resourcemapping("entitledrequest")     public void getserviceautocomplete(resourcerequest request, resourceresponse response) throws ioexception {               string elemprefix = request.getparameter("pfx");             string acc = request.getparameter("acc"); // found null             string mac = request.getparameter("mac"); // found null  }...

use @requestparam annotation read parameters.

@resourcemapping("entitledrequest") public void getserviceautocomplete(@requestparam("pfx")  string elemprefix, @requestparam  string acc, @requestparam string mac, resourcerequest request, resourceresponse response) throws ioexception {  }

reason:

the parameters sent ajax doesn't fall in portletnamespace. hence, not part of resourcerequest can found in normal httpservletrequest. spring searches @requestparam names in httpservletrequest.

you can either use approach suggested me -or- can add <portlet:namespace/> parameters in ajax call keeping controller code intact.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
