of course can't reach action because have wrong url in js code. 

case "prcmmgmtadmin": window.location = "prcmmgmtadmin.do?methodname=getviewpricemanagementadmin"; break;

you can use html:rewrite tag rewrite url in jsp

case "prcmmgmtadmin": window.location = "<html:rewrite action='prcmmgmtadmin'/>"+"?methodname=getviewpricemanagementadmin"; break;
