Servlets :: Filter Not Being Called

Nov 10, 2014

I have Filter that is randomly being called and randomly not being called without any logical reason...The mapping is very simple:

<filter>
<filter-name>MyFilter</filter-name>
<filter-class>com.me.MyFilter</filter-class>
<init-param>
<param-name>ignorePaths</param-name>
<param-value>res/</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>MyFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

[code]....

So, init is called, so it works... but most of the time the doFilter method is not being called at all... what am I doing wrong?

JSF :: Lifecycle Is Not Getting Called After Servlet Filter Forward Or Redirect

Jul 11, 2014

I have a scenario here where the JSF lifecycle is not getting invoked. I have a filter, whose responsibility is to filter only authorized requests.the code of the filter is given below

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest)request;
HttpServletResponse httpResponse = (HttpServletResponse)response;

[code]....

now in the else block i am filtering the unauthorized requests, and sending them back to the Login.xhtml page of the application.The problem i am encountering here is that, the images and styles associated with the page are not getting loaded, what i am thinking is that when i am using redirect or forward, the FacesServlet is not getting called, and it is directly going to Login page i.e. no Lifecyle is being called.how to Filter the requests and at same time not lose the styles?

Am I right on this?, if so how to Filter the requests and at same time not lose the style?

Write A Class Called Coin Which Will Be Used By A Program Called CountFlips

May 1, 2014

i am trying to write a coin program:Write a class called Coin which will be used by a program called CountFlips.

1. The class, is an object created from this program. It is composed of data values and methods. It should contain a main method and should output the number of flips done (an integer that will be read from the user), the number of heads and tails that occur.

2. The CountFlip class will flip a coin multiple times and counts the number of ‘heads’ and ‘tails’ that result. This class should have a method called flip() of type void; a method called isHead() of type Boolean and a toString() method that will return the current face of the coin as a string.

So i created 2 classes, one called Coin.java & the other CountFlips.java,

PHP Code: package test;
public class Coin {
private final int heads = 0;
private final int tails = 1;
private int facetype;
private int flips;

Use Switch Or If / Else Statement To Filter Out Data Not Required For App

Feb 21, 2015

I'm using jsoup to parse a calendar page.

I want to use a switch or if/else statement to filter out the data I don't need for the app. This is by no means anything more than a draft because java is easier to work with than android.

Element table = doc.getElementById("launch_calendar");
Iterator<Element> iterate = table.select("td").iterator();
if(iterate.hasNext()){
for(iterate.hasNext();;){
counter++;

JSF :: Get Data From Managed Bean Method After Servlet Filter

Feb 15, 2015

I have a situation to load data while JSF page loads. Also have a filter which populates user information from http request.

I was expecting the filter first to populate the user information and in the managed bean get method to verify the user information and get the data (from database). But in this case i see the managed bean get method is invoked before filter populates user information and i get null pointer exception because the user information is null.

I had to work around to get the user information from FacesContext in the managed bean get method because the user information wasn't available. Is there a way to make sure the filter is invoked first?

Regex To Filter Any Word In Any Order In Column Of JTable?

Jul 28, 2014

I created filters for every column in my Jtable however, some of these columns have more than one word inside of them and my filters will only filter them based on the first word. For example if I had a first and last name in one column, it will filter the table if I enter the first name in my filter text field but it will not filter that same column if I only input the last name. What is a good regex expression to filter any word in any order?

public static void filterRows() {
String filterId = idFilter.getText();
String filterFrom = fromFilter.getText();
String filterTo = toFilter.getText();
String filterCC = ccFilter.getText();
String filterDate = dateFilter.getText();
String filterSubject = subjectFilter.getText();

Program Can Accept Multiple Filter And Sort Commands At One Time

Mar 9, 2014

What I'm supposed to be doing is making it so the program can accept multiple filter and sort commands at one time, and each should be separated by a whitespace.I was thinking about parsing the input again, using whitespace as the delimiter, then normally progressing with each token, as though there was only one command.

However, coding this the way I'm doing it will firstly probably take hours, and secondly, it's likely not even right. I don't have any real way to determine which token contains which data from the Song objects.These are the specific requirements for this portion:A sort/filter command consists of one or more of the following options:

-year:<year(s)>

-rank:<rank(s)>

-artist:<artist>

-title:<title>

-sortBy:<field>

Any number of these options may be given, and they may be given in any order. If multiple options are specified, they will be separated by whitespace.

GazillionSongs Class (the main)
Java Code:
import java.util.*;
import java.io.*;

JSP :: Custom Tag Not Called At All

Jun 30, 2014

I am working on a project that uses a custom tag in a JSP file. Here is the tag descriptor

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<taglib>
<tlibversion>1.0.0</tlibversion>
<jspversion>1.1</jspversion>

[code]...

Everything seems working fine except that the custom tag handler does not get called at call. I set breakpoint and it never stops there. The JSP page is displayed fine, only not showing the custom tag content and there is no logged error/warning from the log. The tld is found fine. Like what classes called/validated the tag handler so I can logging those classes at DEBUG level to see what goes wrong.

Polymorphism - Which Method Gets Called

Jan 29, 2015

While studying polymorphism , i have some doubts that i am unable to clarify ..... Here they are :

Suppose our inheritance ladder be :
C1 <- C2 <- C3 <-....... <- C100
where C1 is most general (superclass) and C100 is most specific class .
Now , if i write java code in my main() :

C21 Obj = new C100();
Obj.someMethod();

So, what will happen in scenarios as given below :

Scenario - 1) If someMethod() is only defined in C1 ? How will compiler search for this someMethod() ?Will it be executed ?
Scenario - 2) If that someMethod() is static and only defined in C1 , then how will it be searched and executed ?
Scenario - 3) If someMethod() is only present in C100 , then what will happen ?

Method Called At Start?

Nov 24, 2014

So, I have a gameOver() method that should when oval goes out of bounds abort game but, as soon as I start the game it runs the gameOver method. I've been looking over it for a while trying different things. I think what stood out to me is removing the abort sequence the game runs mostly as it should after, popup is closed and that if I replace game.gameOver(); with ya = -1 the ball bounces off the wall.

gameOver()
public void gameOver(){
JOptionPane.showMessageDialog(this, "Game Over", "Game Over", JOptionPane.YES_NO_OPTION);
System.exit(ABORT);

Write A Program Called GeometricMean

Nov 24, 2014

Write a program called GeometricMean that prompts the user to

1.Enter the number of values (total number of instances) that should be processed

2.A set of values to be processed (in a while loop)and then calculate the geometric mean of the values entered. You should use a while loop to perform the multiplication part of the calculating the geometric mean. The program should output the initial data and the labeled geometric mean. Consider printf, and DecimalFormat.

My Program:

import java.util.Scanner;
public class GeometricMean{
public static void main(String[] args) {
