// begin [file=”C:\\UseForward.jsp”;from=(7,6);to=(11,8)]

// end
// begin [file=”C:\\UseForward.jsp”;from=(12,10);to=(15,24)]
if (true) {
out.clear();
String _jspx_qfStr = “”;
_jspx_qfStr = _jspx_qfStr + “?employee=” + “Bob”;
_jspx_qfStr = _jspx_qfStr + “&title=” + “Senior Engineer”;
pageContext.forward(“SamsHome.jsp” + _jspx_qfStr);
return;
