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 a servlet. Users from other machines access that servlet and I want to capture the remote user's UserName and do validation over that.It's just a simple servlet and no login/password is present. I tried request.getRemoteUser(), but its of no luck.
I need the username produced by this program to be in all lower case. The code is below.

I am creating a login form for my project and it works great,the issue is that i want to open up different forms dependent on the username and password that i enter.for example if i enter a password 'manager' then it should open the manager page,or 'employee' should open the employee page.
I'm thinking that it is just a case of creating another sql query but i have tried and i cannot see the solution,i can open the employee page by default but that is not what i am trying to achieve. I am using an sqlite database which holds the username and password.
Here is my code
private void btn_LoginActionPerformed(java.awt.event.ActionEvent evt) { // code to login to the back office system String sql =" select username,password from Employee where username =? AND password =?";//sql query try{ pst =conn.prepareStatement(sql);
I have a problem with my code i try to identify users by password and username but I cannot recognize only the last row in my table in database what can i do ....
Now, I have got a comment saying I should get the database connection from connection pool. And one more issue is that I have used the function System.getProperty("user.name") to get the username which i have logged in. But this code will be run on Unix which will not support this function. Any function where I can get the windows username. There is a function getUserPrincipal(), but this function returns a NULL. How to resolve this.

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 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>

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".
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
if (TxtMobile.getText().length() < 11) { rooms.setVisible(false); JOptionPane.showMessageDialog(getRootPane(), "Mobile number should be 11 numbers long", "Mobile Error", JOptionPane.ERROR_MESSAGE); TxtMobile.requestFocus();
} else if (TxtMobile.getText().length() == 11) { rooms.setVisible(true); }
No compilation errors but code doesnt seem to be working. IF mobile number input is less than 11 numbers an error message dialog appears to alert the user then is supposed to focus on the text box in question. But instead after clicking the ok on the dialog box, the next rooms form shows up even though ive set that to setVisible(false).
How to use validation on a label or textfield in java.
I have a textfield and i want that only username with @ sign will be taken by the program or gives an error.or a textfield that can only take numeric values or whatever the developer wants to take from user..
I am very new to Java. I have been working for a couple months on a program for school. It has not gone well. I finally was able to scrap together a working program, but i left something out that needs to be. I have to include input validation to check for negative values, prompting users to re-enter values if negative. I have included my current code, the program works perfectly, but what to do about the negative numbers.
Java Code:
package gradplanner; import java.util.Scanner; public class GradPlanner { public static void main(String[] args) { Scanner input = new Scanner(System.in); int numofclasses = 0; int totalCUs = 0;
I want to validate an email input. The email input can only have one @ and at least one '.' after the @. I would like to ask if my regex pattern is correct.
YOUR CODE HERE import java.util.InputMismatchException; import java.util.Scanner; public class email { public static void main(String []args) {
import java.util.Scanner; public class PassCode { public static final String SPECIAL_CHARACTERS = "$,#"; public static void main(String[] args)
[Code] ....
I'm having trouble with the code using char[]c, for the special characters. Every thing else seems to work correctly, expect for the special characters.
