I have the same Java scriptlet copied and pasted into multiple .jsp files. I would like to replace it with a solution that's easier to maintain and has better readability
<%
if (!MediaUtil.validateAuthorization()) {
out.println("Unauthorized");
} else {
String srcquery = request.getQueryString();
if (srcquery == null) {
srcquery = "";
}
User currentUser = UserService.findCurrentUser();
if (currentUser == null) {
out.println(User.MESSAGE_NO_USER);
} else {
%>
<html>
<head>
