JSF :: Populate PickList - Value Is Not Valid Message
Jan 16, 2015
I am creating a JSF 2.0 project, and I am facing a problem when using the rich:pickList (richfaces 4) component with a custom converter.
I can populate the picklist left column rightly. But, when I move some item from left list to the right (by clicking in the pickList "add" button) and I try to submit the form that contains the pickList, I receive the following error message:
"mainForm:picklist: Validation Error: Value is not valid"
I have already overridden the methods equals and hashCode in my model class (Pessoas.java), but the problem remains.
cadastroEvento.xhtml
<rich:pickList id="picklist" converter="ApresentadorEventoConverter" value="#{CadastroEventoBean.pessoasSelecionadas}" var="pessoa" sourceCaption="Pessoas disponíveis" targetCaption="Pessoas selecionadas" listWidth="365px" listHeight="250px" orderable="false">
<f:selectItems value="#{CadastroEventoBean.pessoas}" />
<rich:column>
[Code] .....

I am required to make a console calculator that takes the values as strings and turns them into doubles. The user needs to be able to enter something like 3+4+5*9/13 on one line and the application give the answer. As of this point I am currently on at the last section as making the user be able to enter the expression and present the answer. I have added an array list containing + - / * and the same with the numbers 1-9...I now need to actually get the information to all come together. I'm not sure how to do that. I *think* I have all the parts for it to work.
public static void main(String[] args) {
String input = ""; // initalize the string
boolean isOn = true; // used for the while loop...when false, the
// program will exit.
final String exitCommand = "Exit"; // exit command
[code]....

I have some problems about performing regular expression. In the following code, the output as a result is being "valid last name". But in my opinion, it should be "invalid last name". Because "Doe" has not any space, apostroph or any hypen. Look at the regular expression statement: "[a-zA-Z]+([ '-][a-zA-Z]+)*"
package deneme;
public class Deneme {
public static void main(String[] args) {
String lastName = "Mc-Something"; // Mc-Something
if(!lastName.matches("[a-zA-Z]+([ '-][a-zA-Z]+)*"))
System.out.println("Invalid last name");
else
System.out.println("Valid last name");
}
}
I know that the asterisk qualifier means character(s) in any number.(Is this wrong?) So for "Mc-Something", 'M' corresponds to [a-zA-Z], 'c' corresponds to +, - corresponds to [ '-], 'S' corresponds to [a-zA-Z], "o" corresponds to +, and finally "mething" corresponds to *, doesn't they? But for "Doe", there is no any space, apostroph or hypen.

I am working on allowing a user to enter an ID # using JOptionPane. If the ID is valid, then it will display the ID#, student name, and GPA. If it is not valid, then the window should pop up again to allow the user to enter a valid ID. I have managed to get that far.
I am struggling with once a valid ID # is entered, how do I get the loop to stop? I have tried several different ways, but the code below is the most recent one, and it is still not working!
import javax.swing.*;
public class StudentIDArray
{
public static void main(String[] args)
{
String enteredID;
int idNumber;
int x = 0;

Make a password rule, and take input of the password from the user and compare the password with your rule, if the user had entered valid password then print the message, password valid, else the password is invalid for (the whatever) reason.
Rules:-
-Length 8-12
-Should have one numeric character
-No Special Character
-Atleast one UPPERCASE letter
PHP Code:
import java.util.*;
import java.lang.String;
import java.lang.Character;
public class PasswordSpence {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter a Password: ");
String password = input.next();
if (isValid(password)) {

Write a program reads in a series of passwords into an array. Store 10 passwords. After creating the password array, have the reader enter a password and see if it is in the array. Fi it is there, print "Valid password" and if it is not there, print "Invalid password."
This is what i have so far
Java Code:
public class passwordMatch
{
public static void main (String [] args){
String [] myArray = new String[10];
myArray[0] = "jasmine22";
myArray[1] = "jackson77";
[Code] .....
It doesn't compile. It gives me error saying .class expected next to String.myArray[]

I'm trying to do a user validation loop that runs until the user enters a valid binary, q, or Q. I think the rest of my program should work as intended, but here is the areas of concern:
public static boolean isBinary(String num) //Check if the entry is binary
{
for(int i = 0; i < num.length(); i++) {
if(num.charAt(i) != 0 || num.charAt(i) != 1){
return false;
[Code] .....
The program runs without errors otherwise.

I am writing a code in which a user inputs data as a string and that data must be verified as a valid number. A valid number is anything from 0-100. Then all valid numbers are converted into double numbers.
I am having trouble in how to write the validation part of the code.
Is it suppose to be an if, else statement? And if so how is it suppose to be validated?

My homework assignment is: Using a do-while statement, write a Java program that continuously requests a grade to be entered. If the grade is less than 0 or greater than 100, your program should display an appropriate message informing the user that an invalid grade has been entered; a valid grade should be added to a total. When a grade of 999 is entered, the program should exit the repetition loop and compute and display the average of the valid grades entered. Run the program on your computer and verify the program using appropriate test data.
When I run it, I don't get the correct average. I know that i'm supposed to enter 999 to exit the loop and to display the average, but 999 is being added with the loop. I'm not sure how to make it not do that.

I'm trying to populate my JComboBox with an Arraylist. Using two different classes, a GUI class (with the JComboBox - called it MainGui) and a class where I extract information from a database and put it into an ArrayList (which I call databaseconn).In my databaseconn class, I can print out the content of the ArrayList perfectly fine, but when I try to do it in my GUI class it just prints empty brackets "[]".(What I need it to do is to populate the drop down list in the JComboBox with the hotel information).Here's my code:
//The dataaccesslayer you should use for classes that deal with connection to the database
package dataaccesslayer;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;

I'm having an issue with populating a dropdown list in my HTML form.
I want the form to pull in the values from the Database. I have a connection and I'm able to populate a table with the values.
Now I'm trying to populate a dropdown within a form that will bring in currency codes that are in a column called CURR_CODE from the Database.
<%
//Declare variables
//String con_currency_sdo = ""; // as New Connection
String ResultSet = "rs"; // as New Command
String Statement = "stmt"; // as New Recordset
String selBaseCurr = request.getParameter("CURR_CODE");
