I am giving a call to a Jsp page to perform some functionality by 3rd party tools. After the action performed i want to back to another zul page. But if i do Executions.createcomponent inside JSp directives it throws null pointer exception on Executions.

In the following way i have tried to use Executions. <%@ page import="org.zkoss.zk.ui.Executions"%>

Below is the error.

SEVERE: Servlet.service() for servlet [jsp] in context with path [/module-backoffice] threw exception [An exception occurred processing JSP page /core/upload.jsp at line 213

210: Map<string, object=""> args = new HashMap<string, object="">(); 211: args.put("OcrArgs", ocredText); 212: //Executions.sendRedirect("/core/folder/scantoocr.zul"); 213: Executions.createComponents("/core/folder/scantoocr.zul",null, args); 214: //request.setAttribute("ocredText", ocredText); 215: //response.sendRedirect("/core/folder/scantoocr.zul"); 216:

Hello Sailu,

Since you are in a jsp page, you can use jsp commands to redirect to any web page including zul pages as shown below:
