2. In the program, if there is a judgment of if (aaa == null), how to find a simple picture? End the following doIt () function?

code show as below,


// @Override
public void doIt (HttpServletRequest request, HttpServletResponse response)
throws EXXXException, EXXXXFatalException {
Ranch
String urlAllOK = "/plugins/DelDocsPlugin/jsp/End21AllOK.jsp";
String urlError = "/plugins/DelDocsPlugin/jsp/Error.jsp";
Ranch
ServletContext sc = getServletContext ();
if (sc == null) {
String returnSearchResultXXXList = "Failed in deleted!";
sc.setAttribute (KEY_RETURN_TYPE_ERROR_XXX, returnSearchResultXXXList);


try {
sc.getRequestDispatcher (urlError) .forward (request, response);

} catch (Exception e0000) {
e0000.printStackTrace ();
}
}

Use JavaScript and RequestDispatcher dispatcher=request.getRequestDispatcher("/admin.AddJob.jsp?id=5");
