EJB / EE :: Validation For User / Email And Password Doesn't Works
Dec 23, 2014
I having problem on validating email and password whether does it belongs to a registered members or not. I'm using NetBeans and created a database, table name as members. I have done setting up connection pool and fill in data to my members table.This is my members table data.
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.
There is a specific function I have added to a program I've been working with for a while which involves retrieving data from a website. Here is that code:
Java Code: public String getWebData(String urlString, String add) throws IOException{ String output = ""; try { //+s being the token, for example if dictionary.com was being used add = add.replace(" ", "+s"); urlString = urlString + add; URL url = new URL(urlString); InputStream inputStream = url.openStream();
[code]....
Anyway, when I run this program within Netbeans, it works perfectly. I have a backup of the project in eclipse as well, and I've copied all of the code over and tried running the same thing in Eclipse - exactly the same, it works perfectly. The problem is whether I compile the the code in Netbeans or Eclipse, the exported runnable jar for some reason has an issue with this one method. It doesn't crash, and it seems to be doing something, but it is by no means giving me the data from the website like it is supposed to.
My homework is asking me to write a program that prompts the user to enter a password and displays "valid password" if the rule is followed or "invalid password"
Sample enter a string for password: wewewx valid password
It's being graded on Design of my GUI Dialog box User friendliness Creativity
My current issues with the current code I have written is simply the password doesn't work unless it starts with 2 digits, the other order it displays as wrong. and I have no idea how to add a GUI.
I am a first-timer using J2EE and here on coderanch.com and wanted to make a Simple Email-like System which a Registered User can Send Message/Email to another Registered User. how to do it. I have already my register/login process done but I'm stuck on how to make the Email. And I have an sample Bootstrap for my UserInterface which I want to use.
I have a Registration Form in which I am registering user to perform some sort like Entering messages I want to perform some Server Side validation.
Like suppose a user has Enter an Id then as soon as he start entering the Id then I want that this Id should be checked in database that if this Id exists in database or not.
and similar types of validation I want to apply on other fields to.
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;
Some web site offers feature of "remember user id/pwd" so next time when you access the same web site, it automatically pre fill out the user id field and or password field for you. How is this kind feature implemented ? I am not talking about the auto-complete function here.
This is the java code that I wrote for a password:
// java application that asks the user to enter a password import java.util.Scanner; //program uses class scanner public class password{ //main method used to execute java application public static void main(String args[]){ //create scanner to obtain input from command window
[Code] ....
here is the output of the code when I run it :
entered the passwordreason Try againPress any key to continue . . .
The code compiles without errors. The problem is when , I entered the actually password that I declared in my code, it doesn't output "You entered the correct password" but it instead outputs "Try again", which is supposed to be the output if you've entered the incorrect password. What did I do wrong?
I am new to JAVA GUI programming and was wondering how you go about getting and testing if a password field text equals something. For example, if the password equals "password" then do something.
I have a Java application that was built by a third party and my task is to embed this in a web site. To do so I got an HTML snippet, a .JAR and da .DAT file that seems to be called by the app. I tested this locally on my machine and it works ok. After uploading to the web server I get an error message
NumberFormatException For input string: "i>>?<html>"(the question mark is actually upside down, the >> is really one character)
At first sight this looks like a common issue with UTF-8 file being delivered when the file itself holds only ANSI characters (or vice versa). So I made sure that the .HTM and the .DAT file are indeed stored in ANSI 8-bit (and not Unicode 16-bit) format. However, this does not solve the issue. The .HTM file itself also holds a ISO 8859-1 directive. The server is set to deliver UTF-8 by default. I cannot change this due to a huge lot of other dependencies.
So I am not sure if my suspicion is right - is it indeed a character set issue? Or is it something else?
I have create a program that takes a random array which is created by starting from 0 and adding Math.random() (double between 0 and 0.999) n times, and calculates the weighted average of each position within a certain radius. I currently have a program that does this but i was wondering how to create one using a torus. The basic principle is the last element is now equal to the first element and when the first element updates its position it takes into account the difference between the other elements including some of the last elements in the array.
Heres the code so far that works for one iteration. After one the code is incorrect and calculates the wrong values. I think using a circular list or a ring buffer may work but i have little experience with either.
import java.text.DecimalFormat; import java.util.Scanner; public class Torus { public static void main(String[] args) { DecimalFormat df = new DecimalFormat("#.###");
I am having issue with jmenu popup in netbeans. It only sometimes works. Sometimes I don't get a java popup at all. Sometimes my File and Edit options are completely missing. This is what my code looks like.
import javax.swing.*; public class menu { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here JFrame f = new JFrame(); f.setVisible(true);
I have gf 4.0.1 and swing client. I want to get EJB over SSL. I've set all certificates. However, I can get it work only when client and server are at the same host. What I see in tcpdump when they are at the same host:

I have a problem using JFreeChart with JavaFX. I wrote a small program here . At first the graph likes this:
I use fullScreen function to display the JFreeChart Line Chart Demo 2. Here I use SwingNode, ChartPanel to embedded JFreeChart into JavaFX Panel.(Detail part will be included in code later)
Then I press ESC to exit fullScreen. Then it looks like this:
So far, it's as expected. Then I use mouse drag to enlarge the window. Here comes the problem, as the following picture.
Can you see that, seems like appear another graph. And I must click on the window, then everything will become good. I wish the graph shows well even when I drag the window to enlarge, is there something I missed? And here is my code:
My application with Oracle Database only works with Ethernet, I tried to connect via wireless without any response. When I run the command netstat the port state is WAIT TIME and then be closing. The clients machines run Windows 7 and 8 and the server run Suse Linux Enterprise Server 10 SP2, if the client machine run XP all works fine. I disabled the firewalls in the both sides.
