JSF :: 2.0 - How To Highlight InputText When Validation Error Occurs
Mar 18, 2014
How to highlight an inputText in JSF 2.0 when a server-side validation error occurs? I have the server side validation,if validation fails, text box color (style) should change. Else it should display in normal color.
I don't understand that the error occurs when I don't initialize the variable myPoint. Whereas, I initialize the variable myPoint after variable declaration and before place of error.
package enumeration; import java.util.Random; public class Craps {
[Code]....
When I initialize the variable myPoint to zero in its decleration, the error disappear. But why? I have already initialized the variable myPoint in default case before the line of error occured..
I have a GUI that prompts the user for information. When they click 'submit', a new customer gets created from a class like so ...
Java Code:
public void actionPerformed(ActionEvent arg0) { Customer customer = new Customer(); // New customer object customer.name = view.getName(); customer.age = Integer.parseInt(view.getAge()); customer.ccn = view.getCCNumber(); mh_sh_highlight_all('java'); I am having difficulties validating my variables for nulls. For instance ...
Java Code:
// METHOD TO RETRIEVE TEXTBOX INPUT -- NAME public String getName() { String name = null; if (jtfFirstName.getText() == null || jtfLastName.getText() == null || !jtfFirstName.getText().matches("[a-zA-Z]+") || jtfLastName.getText().matches("[a-zA-Z]+")){ // Validate name fields JOptionPane.showMessageDialog(null, "<html><i>Improper Input Detected.</i>
[code]...
I can't seem to win with this. Whether the fields are filled in properly or not, I get the error message and the program continues to completion using the name "null".
In my web application (jsf 2.2 + prime 5), when I click the submit button, JSF says: "validation error". I think the problem is related to my equals method contract.
Debugging the equals method, the type received by this method is "Short" (my PK type) and not the object type to compare (professional type in this case). So, equals will return false always!
PK declaration in Entity Class @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Basic(optional = false) @Column(name = "id") private Short id;
equals method: public boolean equals(Object obj) { if (obj == null) { return false;
i get this error when trying to Persist a customer Entity in my web application using netbeans with the default glassfish server persistence provider eclipselink(JPA2.0)
error is
SEVERE: javax.validation.ConstraintViolationException: Bean Validation constraint(s) violated while executing Automatic Bean Validation on callback event:'prePersist'. Please refer to embedded ConstraintViolations for details.
the table that i want to write to has the following colums id ==> primarykey auto increment not null int name == varchar(45) not null phone ==> varchar(19) nationalIdNo ==>varchar(19) balance ==> bigdecimal(6,2) not null default(0.00)
in my addNewCustomer i only need to set name, phone and nationalIdNo only this is my code

I am Having trouble with my program to validate. It is outputting null into the validation statement then it brings back a run-time error to that validation Statement for the String.
public String validateData () { if (nm == null)nm = "Error! Must enter at least one character"; else nm = name; return name; }//end validation method
Why is this happening, and then once that is completed, why is the validation Sentence in tests Scores not able to validate. I traced it back to out put "Error, a number between 1<100".
public void validateTests () { String testschange; if (test1 < 0 || test1 > 100) { testschange = " You have entered an invalid number, between 1-100. Please restart!"; testschange = Integer.toString( test1 ) ;
I will implement a page where I have a List<String> account, then it will populate inputText and its value corresponding of the size of the List.
For example, I have 10 values in List<String> account, it must populate 10 inputText with value on it and an empty inputText beside it (for the user to input some values on it).
I'm trying to write a program that counts the number of times each number in an array occurs. In theory I understand how it work, you take the first element in the array, compare it again the rest of the array and any time it occurs in the array you increment a counter by 1. Then move onto the next element A[1] and so on...
This is what I've done so far :
public static void main(String[] args) { int[] array = {5,6,2,5,2,2,0,1,6}; int count = 0; for(int i = 0; i <array.length; i++) { int val = array[i]; for(int j = i+1; j<array.length; j++)
[Code] .....
I think I'm on the right track as it correctly prints out the frequency of the first 3 elements, but I'm definitely going wrong somewhere as it just doesn't do it right after that!
When an exception occurs that will affect the entire functioning of a program, in other words, the program will not be able to do what it is intended to do, is it best just print the exception to user and run System.exit(1)? And then force the user to run the program again.
I am currently truing to make this class instantiate 100,000 dice rolls of 2 dice. And I also need to keep track of how many times each possible total occurs and I am having trouble outputting the result. Right now when I run my code it is just showing the results of each of the 100,000 roles.
public class ltefera_DiceRollTest { public static void main(String[] args) { ltefera_DiceRoll diceRoll = new ltefera_DiceRoll(10); System.out.println("Total # of pips" + " "); diceRoll.printArray(); System.out.println(diceRoll.countDice(2)); System.out.println(diceRoll.isArrayDataValid()); System.out.println(diceRoll.getTotal()); System.out.println(diceRoll.allDifferent());
I'm having issues with JButtons and painting methods, whenever I click a grid on the board, the buttons in the JPanel disappear. Here is the board class:
package GUI; public class Board extends JPanel implements Observer { /** * */ // private static final long serialVersionUID = 1L; private final int boardSizeX; private final int boardSizeY; private final int L = 20;
[Code] ....
I know the code is messy in places, this will be fixed later, just need some pointers on how to solve the JButton issue.
I have problems getting the right number of times for each number of the array. Here is my code:
public static void main(String[] args) { int[] a = { 3, 13, 5, 9, 13, 6, 9, 13, 2, 3 }; int num = 3; int count = numbers(a, num); for (int i = 0; i < a.length; i++) {
Write a recursive Java method countDigitx that takes two integer numbers as input (a number n and digit x) and returns the number of times digits x occurs in number n:
For example if n=23242 and x=2 then the method should return 3 that is the number of times the number 2 found in n.
The game runs fine, however I have to include how many times each letter that is guessed occurs within the word. For example, if the guess is e, the program should print out: The character e occurs in 3 positions. How would I go about doing this??
/* * A program that plays simple word guessing game. In this game the user provides a list of words to the program. * The program randomly selects one of the words to be guessed from this list. * The player then guesses letters in an attempt to figure out what the hidden word might be. * The number of guesses that the user takes are tracked and reported at the end of the game. */
I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() { System.out.println("There are " + findUniqueWords(root, 0) + " unique words."); } private int findUniqueWords(Node subTree, int uniqueCount) { // Base Case: At the end of the branch if(subTree == null){ return uniqueCount;
I need to write an input validation while using the do-while statement. I feel like most of it is good except that it gets stuck inside the brackets of the do statement. After I enter an input, it just keeps asking me over and over for an input. Then I have to make it s if you enter an input that is out of range, you have to keep entering an input until it is in range.
Java Code:
do { System.out.print("Please enter the amount of spaces the letters will shift... "); shift = uInput.nextInt(); } mh_sh_highlight_all('java'); Java Code: public class ShiftEncoderDecoderDriver { public static void main(String[] args)
I want to be able to check that the data for the ID is limited to a certain collection of characters formatted in a certain. For example, I may wish to limit it to 5 lowercase letters or numbers, or a combination of both. How could I do this?
I have a JSF page for changing login credentials and i preferred to use Java validations instead of JSF validations on the inputText. The password validation works fine but the username validation does not produce any output. This is my JSF form
HTML Code:
<h:form> <p><strong>Please type your new username: </strong> <h:inputText size="15" value="#{register.newUsername}"/></p> <p><strong>Please type new your password: </strong> <h:inputSecret size="15" value="#{register.newPassword}" /></p> <p><strong>Please retype new your password: </strong>
I have an xml file whose data needs to be validated with 250+ rules, the size of the xml can range from 4MB to 50 MB. Have the following questions.
1. Where the Rules should be defined, as i would like them to dynamically controlled(instead of hard coding) 2. Given the size of the data and input being xml, how should i approach this problem(considering the rules might change etc) 3.The names of the UI and XML tag names will be different, so when should the translation takes place
Following is the structure of the xml :
<DATA> <Parent> <Fields> //All the data like name, age, height, weight, blood group etc goes here </Fields> <Childs> <Name = 'Andrew' id = 7560>
How do you do validation in java for primary key lets say the table got combination of two columns as primary key,how can i validate that if use enter already existing value...
I am trying to validate the phone number with a method called isValidAddress and whenever it gets to that line of code in the while loop I get a lot of red line java exceptions. I am referring to lines 130-138
