1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?
2. All non JSF tags will not generate UIComponents in server side, right?
3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?
When i access to this page and save it as xml in realtime, the tags in xml file saved is empty while it is initialized and everything is working properly.

How can i access to content of this xhtml page and save it on disk?
I am building a room management system in Java (Netbeans) and Ms Access. The jasper report is only showing code (source view) instead of design view. The GUI JFrame and Login JFrame are not displaying records in the database and the buttons are not working. Also the labels and text fields are not neatly arranged. The connection to the database is not displaying records.
Connection to the database. COIRMS.java
package Login; import java.sql.*; public class COIRMS { Connection con; Statement st; ResultSet rs; public COIRMS ()
Write a method named diceSum that prompts the user for a desired sum, then repeatedly rolls two six-sided dice until their sum is the desired sum. Here is the expected dialogue with the user:
Desired dice sum: 9 4 and 3 = 7 3 and 5 = 8 5 and 6 = 11 5 and 6 = 11 1 and 5 = 6 6 and 3 = 9
This is my code:
import java.util.Scanner; import java.util.Random; public class mod { public static void main(String[] args) { diceSum();
[Code] .....
it works for numbers 2 - 4, but any number from 5 - 12 just prints one output, which is not the correct desired sum.
My output of my app its outputting the correct data just no the format ...
code :
DatabaseQuery.java : import java.io.*; import java.sql.*; import java.util.*; public class DatabaseQuery
[Code] ....
Current output:
Stock holdings by User
User ID User Name Stock - Description ------------------------------------------- admin01 Default Admin DELL Dell Computer Corp admin01 Default Admin MSFT Microsoft Computer Corp
[Code] ....
Desired Output :
Stock holdings by User
User ID User Name Stock - Description ------------------------------------------- admin01 Default Admin DELL Dell Computer Corp MSFT Microsoft Computer Corp ORCL Oracle Corp
This was my initial question: I am confused as to why this won't return the desired value. I keep running into an infinite loop or data is returned that I searched.
I still need to work on whether a user enters a search that doesn't exist......that is where I am stuck....
code has been updated......
int low = 0; int high = subArray.length; while (low < high) { System.out.println("You have entered the while loop"); int mid = (low + high) / 2;
I am working on eclipse kepler, JSF 2.2 with PrimeFaces 4.0 / Mojarra 2.2 library.
actually there are 2 Problems:
I still get this server message no matter what I do.
(( javax.el.PropertyNotFoundException: /Order.xhtml @28,76 value="#{kk.refugee.id}": Target Unreachable, 'refugee' returned null))
and if I delete the input text puls the hidden, the message keeps pop up for 'material' selectOneMenu. -
I have no chance to examin : ((is this javascript code correct, to copy the value of one component to the other.)) these are my xhtml file and java calsses.

In my Icefaces 3 application I have a ManagedBean ancestor that defines common attributes to those they spread it. Including CSS styles to be apply at the menu as icons depending on whether they are selected or not. Classes that extend the CommonMBean class define styles. My question is what do I have to put in the language experssion styleClass to tell him that the getter to use is that of the parent class.
CommonMBean.java package com.omb.view; public class CommonMBean private String menu1Css = ""; private String menu2Css = "";
Currently, my program converts Long values to String. And when I test it out, it do print out the correct output. However, when the converted String value is passed over to be written in a text file, it seems that BufferedWriter isn't printing out the outcome that it's supposed to be.
saltVs = Long.toString(saltV); System.out.print(saltVs); //will print out 79723172
Now the problem is here...It only prints out the last digit of the String value (instead of 79723172).
Here is my FileWriter/BufferedWriter part.
Why is that when I run my program using command prompt, it prints out the output that I wanted, but however when it comes to writing to the file, it doesn't come out right.
-In your main, you should create a thermostat and thoroughly test it. Be sure to showcase time passing and the temperature reaching the desired setting. Also, showcase switching modes from heating to cooling.
My question is, once it reaches the desired temp, would the thermostat turn off, and then how do you show switching from heating and cooling.
This is what prints.
Thermostat is: true Thermostat is: false The desired temp: 70.0 The current temp: 69.0 Tue Feb 25 19:06:21 CST 2014 Tue Feb 25 20:06:21 CST 2014 Thermostat is: true Thermostat is: false The desired temp: 70.0 The current temp: 70.0
Here is my Class:
import java.util.Random; import java.util.Date; public class Thermostat { private double currentTemp; private double desiredTemp; private double heatingThreshold; private double coolingThreshold;
I am new to JSF and when i try to implement a sample application im getting this wierd error of page not found(.xhtml). Here is the code i have created..
Bean class :
package com.trail.beans; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; @ManagedBean @SessionScoped public class UserLoginBean {
And in the server getCustomerList() accessed to database, how many times getCustomerList() would be called from I request the xhtml page?. I have read this would be called several times because of JSF internals and It would be better to store it in a variable and access this variable.
1. Is this true this would be called several times? why?
2. If the previous statement was true, how to avoid it, I mean not call the method from a service?
My project consists of a web app where a user can select a area from a picture and f.e. if it is a office layout he can input the worker name and any peace of hardware that the area might have. In this case there are two categories: Hardware and Computer. Hardware - it has 5 dropdown lists consisting of printer, scanner and etc. Computer - like Hardware consists of many dropdown lists which add up to components such as processor, motherboard and etc. For me, considering this is my first ever web app project, is a huge step towards web development, I have used various mixes of Java, javascript and primefaces code.
My current problem: When a user selects an area he gets a dialog box where he is prompted to select his desired input, afterwards the user clicks the 'save' button and get's another dialogbox which has a resume of what he has selected so he could check out his input and save it by clicking the 'save' button in the resume box. My problem is that when the user clicks the save button the button calls a method which takes all the input and creates an Area object (Area object consists of various objects such as: Coordinates, Dimensions, Employee, ComputerList and HardwareList) and sends a query to the database, but all the values I get is null.

I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.
I noticed it is a huge success to have the backgrounds of games move and the character just move up and down and dodge obstacles.How Do I make a background that scrolls horizontally to the left? I know how to keep the character in place with up and down to move, but not sure how to go about making the background move with obstacles.
1. I read somewhere that instead of looping through every player (below), you use could Events to do it for you:
for (Player player : this.getPlayers()) { if (player.getLocation().getX() == 10) { } }
I'm not sure as to how to use Events in place of a for loop. I've been thinking on this for days, but I'm still stuck. Any example of using an Event instead of a for loop?
2. Is there any way to accept multiple connections on a server without using a while loop? Maybe use Events to handle the acceptance of connections?
Is it possible to enable & disable "jdk.certpath.disabledAlgorithms" property programmatically. I want to remove all disabled Algorithms for some time and later I will enable it.
Or is it possible to enable only for a particular place & not in a JVM level. I want that Algorithm need to be enabled for a piece of code, but I don't want it to the remaining part of the application.
I am developing a web application using JSF-2.0 on weblogic 10.3.6. I am using Facelets as VDL. I have 5 different machine. They are different according to their OS and their geographical location. On my first xhtml page server (machine) is decided. Then on next page file upload and rest of processing takes place. My restriction is that SSO configuration can be done on only one machine.
So I am restricted to using xhtml files from only my primary server where SSO configuration is done. But I have to connect to servlets or managed-bean of different machine as requests are machine specific and file needs to be uploaded to those machines for processing. So I cannot use redirectUrl as I need to be only on one machine. Is it possible that xhtml on one server can talk to managed-bean on other server(different machine)?.
I am making a Dice Roll GUI and I have most of it down and I only need this constructor to work for the program to work (I think). I don't know where to place the constructor, I tried placing it around the RollButton class but it still didn't work and gave me java error constructor in class cannot be applied to given types
Here's my constructor:
private JPanel panel; public RollButton(JPanel panel){ this.panel = panel; }
I am currently trying to solve a programming problem on this site, and the problem includes working on a 100 digits of decimal places of a certain irrational number. I tried using BigDecimal class but it displays, correctly me if I am wrong, just 20+ decimal digits. Is there other way to do this?
