request is accessible inside the scriptlet expressions, because it’s an argument of the method in which these expressions are evaluated (_jspService). But if you want it to be available in your own methods, you must declare it as an argument:
<%
String fname = request.getParameter("fname");
String username = getVal("lname", request);
%>
<%!
private String getVal(String param, HttpServletRequest request) {
return request.getParameter("fname");
}
%>Note that you shouldn’t be using scriptlets and getting request parameters in JSPs in the first place. JSPs should be used to generate markup. Do your processing in a servlet/action, prepare the data to be displayed by the JSP by creating and populating beans in the request scope, and then dispatch to a JSP, which should use JSP EL, the JSTL and other custom tags exclusively.
