Spring framework and export PDF

[veritas]

SmartClient : v11.1 eval
Browser : Chrome, IE v11

I'm developing a web application under smartClient pro v11.1 and spring java framework.
what i want to to is to let canvas to export to a pdf file.
The client side source codes are so simple but what I should do to my server side spring resolver and coltroller ?
Are there any example source codes ?

Here are the javaScript codes.

   var config = {
       actionURL     : '/export/exportToPDF.do', 
       skinName      : 'Tahoe',
       exportDisplay : 'download'
  };

  isc.RPCManager.exportContent( myListGrid, config );

Thanks.

Nothing. Use the default web.xml registration for the IDACall servlet and do nothing with Spring.
