We have this website that is run on two web applications. The first web application hosts the home page and clicking certain links in the home page would forward it to pages of the second web application where certain functionalities can be done. Now, there has been an initiative to redesign the site to have a login page and only logged in users could browse it. This would mean a login page being created in the first app, and when links to the second application are clicked, the pages are supposed to forward to it with the same session of the user that logged in.
We have already creating handling to pass the session from the first app to the second. Logging out from the first application would also invalidate the same user session in the second application. My questions is, is this a bad idea? would it be better to combine the two apps even if it would mean a huge impact?
or is there are better way to do this? like set it in web.xml. I have read that you cannot use two context for it.

my application shows a profile. The profile has various interactors. I'm trying to follow the MVC model, so I neeed to tell my controller that something was selected. But the profile has many elements that can be selected(mostly labels, so not setActionCommand), how do I tell it WHICH one was it?
how do I separate those interactors? I created a HashMap that maps from JLabels to Strings. When a mouse event occurs I loop trough it to search for the event source. If I find it I fire my custom event.

I am working on an assignment that is to simulate the relationship between a cache and main memory. Basically it is supposed to be a 16 slot cache and we are to have 500 for main memory. I need it to compare the corresponding index for both arrays, then go through then repeat the cache array and compare it to the next 16 of main memory. It is to simulate an direct mapped cache. How to compare two arrays from separate loops.
public class MainMemory {
private short mainMem[] = new short[200];
public void assign(){
short i;
for ( i = 0; i < mainMem.length; i ++){
mainMem[i] = i;

I am implementing the hash join algorithm for a project with a hard coded hash function. I've hashed the first relation and I've hashed the second relation. The problem is when hashing the second relation I only know how to add the tuple from the second relation into a third relation and not also access the first relation tuple at that time
The "hashtable" structure contains the hashcode of my key as well as the tuple stored in a string. This code below is taking place in the hashing of the second table, my function determines that both these tuples share the same hash code based on the first element in the tuple (element 0) so I add the tuple from my second relation to the qRelation but I also want to add the tuple from the hashtable at that point and I don't know how to access that string
if(hashtable.containsKey(tuple/*(RELATIONA)*/.get(0).hashCode()))
{
//Add the tuple from relation A into qRelation wich matches the
//above condition
qRelation.addAll(tuple/*(RELATIONB)*/);
}

I am trying to create a bukkit plugin. I need to be able to read from a separate config file but do not know how.
I am trying to use a JSON parser to read from a file but I only need a specific line of the file. Would this work?:
JSONParser parser = new JSONParser();
Object obj = parser.parse(new FileReader("/plugins/easyRace/config.yml"));
JSONObject jsonObject = (JSONObject) obj;
String Races = jsonObject.get(var "Races:");

I am creating 2 different java codes for encryption and decryption separately based on RSA algorithm. The codes also involve swings for GUI. The problem with these codes are that my string is getting encrypted but after decrypting it,i do not get the string rather i get string of random numbers and alphabets. I am posting both the codes.
Encryption code:
import java.math.BigInteger;
import java.util.Random;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class cipher implements ActionListener
[Code] ....
Now the decryption code
import java.math.BigInteger;
import java.util.Random;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class decipher implements ActionListener
[Code] ....
The screenshots for respective codes are as attachments ....

I have two separate java Program that run on the same
computer : Program -1 & Program-2 .
Explain Program-1 :
Name of Program -1 is “InputFrame” that is a simple frame that contain a JTextField and a Button and a JTextArea .
Explain Program 2 : Name of Program-2 is “OutputFrame” that is a simple frame that contain a simple JTextArea that this JTextArea is a Instance object from a class with name of “DisplayFrame” .
This instance object from class of “DisplayFrame” added to frame of “OutputFrame”.Now I want run both Program 1 & 2 simultaneously in the same computer and when I enter a text in JTextField in Program-1 and after click on the Button “OK” that Text Entered in this JTextField In addition to JTextArea in Program-1 display In JTextArea in Program-2 .
I do not want use a share file between two Program-1 and -2 Or DataBase .I want if Program-1 run but Program-2 is not running and i enter a text in JTextFeild in Program-1 , after running Program-2 that Entered Text Displaye in JTextArea in Frame of Program-2 .(Offline Message) .Both Source code of Program-1 and Program-2 is Attached .

I am writing a program that adds together large integers. I have to store each integer in an array of digits, with one digit per array element. Array length is 50 so integer is 50 digits long. I have to store numbers in right-shifting format with leading zeros. For example,
0000000000000000000038423
0000000000000000000000027
Sum.txt contains numbers to be added. There could be one or more numbers per line.each line must be read as string with next() since it's assumed to be a very long number. String of digits needs to be converted into an array of 50 digits. Method CharAt and Character.getNumericValue will be useful. All numbers in each line are to be added. There are no negative numbers and individual number might be 0 or answer might be 0. Answer is always 50 digits or fewer.
BigDecimal or BigInteger are not allowed.
I'm lost where it says to put number with leading zeros in a 50 room array. How do I add numbers after formatting numbers with leading zeros?

I know that I can declare and initialize an member variable inside a class in a single statement but I can't do them on separate sentence. Why?
For example, I am allowed to do the following,
class A{
int a = 5;
// rest of the class
}
But I am not allowed to do this,
class A{
int a;
a = 5; // it doesn't compile even when the variable 'a' is static
// rest of the class
}
Why java don't allow me to do that?

I've been into java for about 4 months now, No complaints so far, it's pretty awesome! So I understand Polymophism pretty good, I did some Animal classes and it worked out neatly.
However. I just can't seem to find my way in OOP when trying to implement in on a Calculator Class I wrote. As you mind know, a calculator can be separated into many classes. But I actually just want it to be separated into some OO like: | Calculator | CalcGUI | CalculatorFunctions | CalcRun.
I tried separating the single Calculator class, however, my calculator Buttons didn't work after that, anymore..
here is my code:
import java.awt.GridLayout;
import java.awt.Panel;
import java.awt.TextField;
import java.awt.Button;
import java.awt.Menu;

I would like users in an application to be able to access and edit their user profiles (Application A). The problem is that the user objects (entities, dao, beans) are handled in a separate application (Application B) which is specifically for managing user accounts. Importing the java sources for App B into App A could be messy and might need configuration of the persistence unit and connection. I'm thinking it would be better to inject an EJB from App B to App A to query the user DB and return the results so a user profile form is rendered in App A.
I know how to inject EJBs within the same application, but I'm not so sure about how it's done across different applications or even if that's the most advisable way to achieve what I want. it's better practice to inject an external EJB into App A or simply import the classes from App B and use those.
@Stateless
public class UsersDaoImpl implements UsersDAO {
@PersistenceContext
private EntityManager em;

I am attempting to maintain separate files for different types of "messages" (user messages, field labels/buttons, data values). In this attempt I am trying to get the description of different data values. For example, a UserStatus "A" might be displayed as Active or Activo.
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="defaultEncoding" value="UTF-8"/>
<property name="basenames">
<list>
<value>WEB-INF/locale/messages/messages</value>
<value>WEB-INF/locale/fields/fields</value>
<value>WEB-INF/locale/values/values</value>
</list>
</property>
</bean>
Here are the relevant entries in the values_en_us.properties file:
user.status.A = Active
user.status.I = Inactive
user.status.P = Pending
I would like to build an Enum for each type of value that I can get the localized value from. In the code below, I have hardcoded the values being passed to the get message to reduce the number of variables when trying to debug this.
import java.util.EnumMap;
import java.util.HashMap;
import java.util.Locale;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public enum UserStatusEnum {
[Code] ....
When this code runs, I get the following message:
org.springframework.context.NoSuchMessageException: No message found under code 'user.status.A' for locale 'en_us'.
On this line of code:
description = appCtx.getMessage("user.status.A", null, new Locale("en_us"));
The application is already showing my custom application error messages I have in the messages localized files, but in that case the ApplicationContext is already available. Because I can get to the contents of the messages_en_us.property files, I'm assuming me config is correct. However, the classes that get the messages content are instantiated by Spring.
The Enums are not created by Spring, so my assumption is that I am doing something wrong in how I am getting a handle on the ApplicationContext or how I am using it.
After looking at the appCtx values in debug mode, I can see that the messageSource > basenames does at least contain my configuration data.
[WEB-INF/locale/messages/messages, WEB-INF/locale/fields/fields, WEB-INF/locale/values/values]
Although I don't see the whole filenames with the file extension anywhere or the property file entries.

I have the following problem:
Let's say, there is a simple Java application. It could either be a Swing or JavaFX or a plain Console application.
Then there are kind of X plugin jars which can be also on the classpath.
The main application (e.g. main.jar) scans the classpath for classes, which implement an plugin interface. For each found implementation it invokes some method on the interface.
The interesting part now is, that upon calling the interface method, some plugins may want to popup a JavaFX window.
And the problem is, that I can't just call Platform.runLater there, because of "java.lang.IllegalStateException: Toolkit not initialized".
And if I somehow manage to call Application.launch() (when? where?) in the plugin then there's the danger, that the second plugin gets "IllegalStateException: Application launch must not be called more than once"
I also don't want to call launch() in the main application, since it is not necessarily an JavaFX application.
Do I maybe need to start separate JVM in the plugin? Could it still communicate with the original JVM then (main.jar)?

So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like
10
150.4
88.4
-3.14
499.4
799.4
1299.8
0
1900.2
901.7
4444.4
This is what my program looks like
import java.util.*;
import java.io.*;
public class assignment7scratch
{
Toolkit_General toolKit = new Toolkit_General();
public static void main (String[]args)throws IOException
[Code] .....
so I dont get an error but this is what my output looks like
----jGRASP exec: java assignment7scratch
This program reads a list of values representing number of miles driven by individuals. It will output the dollar amount their rental cars cost.
Number of miles traveled on the left as well as amount reimbursed on the right

----jGRASP: operation complete.
it also doesn't write anything to my output file, though it does create one.

I want to clarify it whether this below code, when running this loop, will it create separate string objects as strings are immutable or else, will it keep the same reference(as each time inside loop, we use the same name 'rslt') and assign new string value for this?
while(inc < numberOfColumns){
String rslt=rs.getString(inc+1);
rowArr[inc] = rslt;
inc++;

I am having some trouble with a Java program. I have a txt data file, which I will display, that I need to add into two separate arrays. The text file is 8 lines long that is supposed to go into two separate 4x4 matrices. A little background info on this program, reads in two arrays, compares them and outputs the largest elements of the same index and outputs them in a separate array. I somehow cannot seem to figure out how to do this. My code is below:
Data File:
2 7 6 4
6 1 2 4
9 7 2 6
8 3 2 1
4 1 3 7
6 2 3 8
7 2 2 4
4 2 3 1
Code:
public class prog465a {
public static void main(String[] args) {
Scanner inFile = null;
try {
inFile = new Scanner(new File("prog465a.dat.txt"));

I'm not exactly sure what the draw button is supposed to do specifically, all i know is that it is supposed to draw both rectangles and ovals. The problem I am having is that when ever I click Draw Rectangle, it draws rectangles jusst the way I want but when ever I click Draw Oval, the program keeps drawing rectangles. I've tried repaint and clearRect methods but I did not manage to get them to work. I'm not sure what the problem is right here, I just cannot get it to work. Is there anything you guys can see that might be causing this? It's always good to have a different person look at it then myself. Also, I'm trying to implement a boolean for draw oval but I don't know where to put the if then.
public void init() {
length = new JTextField(10);
width = new JTextField(10);
btnDraw = new JButton("Draw");
btnClear = new JButton("Clear");
btnDrawRectangle = new JButton("Draw Rectangle");
btnDrawOval = new JButton("Draw Oval");

I've written most of the code (along with another classmate) to get this to work, but I can't seem to return the encrypted value. I'm also trying to figure out how to separate the digits (or if I'm supposed to) to make the numbers encrypted. The main kicker is that we have to be using methods to return the final values. Everything compiles, (It compiles, but no results really.)
A company wants to transmit data over the telephone, but they are concerned that their phones may be tapped. All of their data is transmitted as four-digit integers. They have asked you to write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four-digit integer number and encrypt it as follows: Replace each digit by the remainder after (the sum of that digit plus 7) is divided by 10. Then, swap the first digit with the third, and swap the second digit with the fourth. Then print the encrypted integer. Do the encryption in a method and send the encrypted number back to main.
Here are the method headers: public static int encrypt(int num) // Takes num as a parameter and returns the encrypted value public static int getnum() // gets one number from the user Example: If the user enters 1234 they should see: 0189
import java.util.Scanner; //Needed for Scanner class
public class LNFI_LNFI_program2
{
public static void main(String[] args)
{
getnum(); //Calls for getnum() method

Imagine having 3 or 4 tabs at the top left as in the default behavior, and one at the top right for some "special" features.
Is there a way to do it? Or is something expected to exist in the future? (or not at all?)

I am trying to create a GUI interface in swing which consists of four classes: a GUI class, which creates a main JPanel, a label, and a JList, which it takes from the second class, a MovesList class that contains a JList and the stuff needed to interface with it. It also has a main class, which basically just creates an object of the GUI class for the main window, and an Other class from which I would like to be able to add an item to the JList. I created methods in the MovesList class to get each component (like getMoveslist, or getMovesListScrollPane), which I then used to create the JList in the GUI class. I also created an addMove method so that I can add an item to the JList from any class through a MovesList object. However, this addMove method only works when called from the GUI or MovesList classes -- it does nothing when I collect from the Other class.
Here is my code:
//Main class
public class TestProject {
public static void main(String[] args) {
GUI mainWindow = new GUI();
mainWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
[Code] ....
When I run this code, I get a window with a JLabel that says "Moves," and a JList that contains five elements -- test 1-test 5, but not a sixth "test from other class." ( using the add move method ) However, when I click on the window, the addMove method is also called, and successfully adds "test 6" to the list.
