I have the below code with spaces on uri and prefix (directive attribute).
<%@ taglib uri=" news.tld" prefix=" news" %>
how to fix without altering the JSP? Can i handle with web.xml or any other property available.
I have hundreds of jsp like this and wanted to handle without code fixes.
I tried JSP trimSpaces but it fixes the namespace but not the attributes.
When using trim-directive-whitespaces in a Tomcat 7 application this expression also get trimmed:
<div class="${item.view} ${item.className}">
resulting in the HTML
<div class="personchild">
instead of
<div class="person child">
On the other hand, when I first assign the expression to a varibale it's fine:
<c:set var="className" value="${item.view} ${item.className}"/>
<div class="${className}">
results in the desired HTML
<div class="person child">
Is this the intention of the trim whitespace directive or does this look like a bug?
In c++, I'm aware that you can use the ignore function to ignore numbers after space, but in string how do I ignore a number after space is found for instance, "109 33" how would I ignore 33?
View Replies View RelatedMay be I did not understand the meaning and usage of attribute "session" in page directive. My understanding is if session=false, in page directive, then the JSP page will not participate in the session. However, I have my welcomepage as below:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" session="true"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
........
.......
<%= session %>
<c:out value="${pageContext.request.session}"/>
if I choose session=true, then both ways of accessing session works , which means the JSP page participated in the session.
But if I change the session=false, then <%= session %> fails, but <c:out value="${pageContext.request.session}"/> does not fail.
how can c:out still show the session, when session = false

I'm trying to loop through a string and depending on the character, add a JLabel to a game. The problem is the character 'L' represents a lantern but is also used in the reply the game gives which is "LOOKREPLY". I've tried to use some code to ignore the LOOKREPLY bit but it's not working. Here's what I've tried.
else if(message.charAt(i) == 'L' && message.charAt(i+1) != 'O' | message.charAt(i+1) == 'Y'){
JLabel localLabel = new JLabel();
localLabel.setIcon(lantern);
panel.add(localLabel);
panel.revalidate();
panel.repaint();
But the first image on all of the JLabels is always a lantern, which is what L represents. As it's only 1 lantern this leads me to believe that it's ignoring the first 'L' but for some reason it's not ignoring the 'L' at the end of LOOKREPLY.
I have made a program, where the user types in a letter M, C or I to identify their major, if the user types m, c or i, my code does not work.
How could I make my program ignore if the letter is upercase or lowercase? My code is posted below. Can I do this in any easier way then adding this type of code for each lowercase letter?:
Java Code:
if (s.charAt(0) == 'm')
System.out.print("Mathematics "); mh_sh_highlight_all('java');
My current code:
import java.util.Scanner;
public class c4e18 {
public static void main(String[]args){
Scanner input = new Scanner(System.in);
System.out.print("Enter two characters: ");
String s = input.nextLine();
if (s.charAt(0) == 'M')

I have a question about an exercise of OraclePress.
public class OompahLoompah {
public static void main(String[] ar){
final StringBuilder str = new StringBuilder("I good! ");
str.insert(2, "look ").append("and nice");
str.insert(str.length(), "!!!");
str.delete(str.length() - 2, str.length());
System.out.println(str.toString().trim());
}
}
The correct output is "I look good! and nice!" , but i don't understand for what .
Why the trim () method does not work? Whether is working on an object String.
How can i make sure that when user enter value there is no space between words example :
NEW YORK MUST BE NEW YORK
I'm trying to make a program that will count each letter like if I put the word
e-1
h-1
l-2
o-1
The problem I'm running into is that if I put something like How now, brown cow? It should give me something like this
b - 1
c - 1
h - 1
n - 2
o - 4
r - 1
w - 4
but it doesn't instead the whole program crashes because of the punctuation marks and the spacing. Is there a way for me to fix that? All I know is that it has something to do with the alphabet[pos(letter)]++;
import java.util.Scanner;
public class CharCount {
static Scanner keyboard = new Scanner(System.in);
//this method should allow the user to enter a line of text (that should all be lower case) and then go to the printResults method
public static void main(String[] args) {
String text, character;
int count;
char letter;
int[] alphabet;
System.out.println("Enter a line of text:");
text = keyboard.nextLine().toLowerCase();// any text entered will be lower case
alphabet=countLetters(text);

I have an array made that represents digits and I am trying to make a method so that if there are zeros in front of the first significant digit I want to trim them, I understand you can't re size arrays so I have created a new array, but my code doesn't seem to run correctly? Here is my code I can't figure out what is wrong I've tried everything: (I put stars around the error**)
package music;
import java.util.Random;
public class Music {
private int length; // length of the array
private int numOfDigits; // number of actual digits in the array
int[] musicArray;

I got situation where i have postal code as 0009 in database and the use is entering 0009 but somehow in my java code it only reading 9 from the xml file
This is how i define getter and setter :
When I debug the code i get this :
passed postalcode 9
if a user entered 0009 I what it to remain 0009
Java Code:
public String Postalcode="";
public void setPostalcode(String Postalcode) { this.Postalcode = Postalcode; }
public String getPostalcode() { return Postalcode; }
In Oracle SQL, when you do trim(column_name), if column_name is blank spaces only (say datatype is CHAR(8)), then "trim(column_name) is null" is true.
In JPQL, if you do "TRIM ( BOTH FROM p.column_name ) is null", does it evaluate to true just like in Oracle SQL?
The reason I'm asking, is my colleague wrote some code in JPQL like below:
... TRIM ( BOTH FROM CONCAT(p.column_name, '#@') ) = '#@'
He said he originally wanted to compare the TRIM result to empty String '', but the result is false, so he concat the column to some junk.
So if after the TRIM, the result is the same junk he added, then the column contains only blanks. I think this works but there could a simpler way to do it.

How can I store in database an user Session attribute along with other informations provided in the same form?
<p:outputLabel value="user ID:" for="informer" />
<p:inputText id="informer" value="#{session.getAttribute('userID').toString()}"
title="informer" disabled="true" />
I've already tested with disabled="false", too, but only the Session attribute is saved as NULL, though it appears in the form field. The other fields are saved properly.
context.getELContext().getELResolver().getType(context.getELContext(), null, "value")
Here "value" is an attribute name. By this we can get data type of the attribute.
By somehow can we set the type also?
I don't know how to read the attribute maxLenth. The way in the image I have done drive me to the error below.!

Piece of Java Code:
int length = Integer.parseInt(spec.getAttribute("maxLength"));

We've implemented the Whitelist and there's an application I need to use the Force attribute with, however, I'm unable to get this to work. As I read it, this code says use Java 1.6_24 for Example.com and any other applications are blocked from running. There are three versions of Java installed - 1.6_24, 1.7_65 & 1.8_25. The Java console shows 1.8_25 being called.
Here's the ruleset.
<ruleset version="1.1+"> <rule> <id location=https://example.com />
<action permission="run" version="1.6_24" force="true" /> </rule>
<rule> <id /> <action permission="block">
<message> This application is blocked due to Java restrictions, please contact the Service Desk for assistance.</message> </action> </rule></ruleset>
I also tried
<action force="true" permission="run" version="1.6.0_24" />
and also
<action force="true" version="1.6.0_24" permission="run" />.
The Java console is still showing version 1.8.0_25.
I'm looking to figure out if it's possible to do the following:
HttpSession session = request.getSession();
session.setAttribute('name', 'Jane_Doe');
// more code here
session.setAttribute('name', 'John_Doe');
Obviously, you can use the HttpSessionAttributeListener to determine which attribute has changed. However, it doesn't return the new value but rather the old one.
You can use the HttpSessionEvent listener to determine when a session object has been changed.
Is there a way you can determine when a session object changes (and it does NOT occur when the setAttribute method is called...) and determine the updated key:value pair?
