In 6.1 sp2 I need to establish a REST service connection through Connect HTTP. I need to send request in JSON format and parse it from JSON to clipboard. I tried below code but not able to save, it is failing in compilation getting error like getJson() function is not defined in Clipboard page API. So my question is, to use below method which class/JAR I can import in Pega 6.1 SP2 . Is it anyway possible to use these below methods in pega 6.1 sp2.
