I've made a login system with a username and a password. The password is visible and I wanna hide it, how do I do that? Here is my code (have used swing);
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Password implements ActionListener {
private String Username = "hudhud";
private String Password = "fitness";

private static Scanner sc;
public Scanner readPass;

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 ....

res=state.executeQuery("select*from conex");
String pass=new String(this.pass.getPassword());
String name=this.name.getText();

I am maintaining an existing Java product (which has a HUGE code-base). I discovered that it is setting (and getting) two of its internal passwords as Java system properties, at no less than 4-5 different places (methods). Now, the problem is, the passwords are being stored as plain text in the Java system properties, and so, the same is visible to external entities, as the application is not using any Java Security Manager. For example, if the application (process) is running on port number 1234, we can run the Java command:
jinfo -sysprops 1234
to view both the passwords as values of the corresponding Java system properties. I wish to ask if there is any remedy to this without changing the existing code-base too much? The desired effect would be to "hide" the two Java system properties (denoting the two passwords) from all external entities.
It may be noted that introducing a Java Security Manager into the application may not be a solution, as if we revoke read permissions from the said two Java system properties using the Java Security Manager, the application codes which read those properties would crash. Same is applicable for storing the passwords in encrypted form, as that would crash all codes within the application which are expecting to read the passwords in clear text form.
To give a bit more context, the said two passwords we are storing as Java system properties are actually passwords to access two key-stores, and Tomcat requires that we store the said two passwords in plain-text format. Any workarounds, such that only Tomcat will be able to see the two passwords as-is, while they will be invisible to all other external entities?
Or, is there any way to place the said passwords in other in-memory locations (like static variables) which only Tomcat can (be made to) read instead of placing them as system properties which is exposed to anyone?

View Replies View RelatedSo I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect
/*
conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");

I downloaded Connector/J in the the binary .zip form and extracted it to my C: drive and put the .jar file into my java directories lib folder. I also added the directory of the .jar file into my CLASSPATH and I still get the exception.
I have configured form based JAAS in my app. Basically, in web.xml I have declared security constraints on certain jsp page, declared specific roles, login and error pages. So, my login form is:
<form id="loginForm" action="j_security_check" method="post">
<p>
<label for="name">Username</label> <input name="j_username"
id="username" type="text" required/>
[Code] ....
This works fine when some user tries to access some of the pages declared in <security-constraint> tag of web.xml.
Container automatically manages login process, redirects to login page and if login details are valid, gives access to secured page.
Now, how should I implement login system so that user can go to login page (possibly same login form) and log in from there?
Is it possible to launch windows, specifically 8.1, directly into a java based program which would serve as the password entry screen? That is to say, instead of using the standard windows screen, could a java based alternative be used?
I have the source code used on jurassicsystems.com. I would absolutely kill to have a tweaked version of this system act as my password entry screen. It is literally something Ive wanted to have done for ages, and this emulation finally means it may be possible.
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

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.

username works perfectly, but when I enter password I get this error.
Java Code:
OKbtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if(Usernametxt.getText().equals("Admin") &&
(Passwordfld.getPassword().equals("Admin2"))){
System.out.println("permition granted");
}else{
System.out.println("permition Rejected");

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.

My code is already running. But the problem is, i don't want to see 0 denomination. like for example if i input 3.86 in (dollars).
dollars: 3
quarters: 3
dimes: 1
pennies: 1
so my problem is. it still showing 0 denomination like this:
dollars: 3
quarters: 3
dimes: 1
nickels: 0
pennies: 1
Currently using latest netbeans and if im correct we are using methods and class runner?.. Anyways here's the code..
for method:
package MyPrograms;
public class Mp3Method {
public int dollars(int dollars,int remainingAmount){
return dollars = remainingAmount / 100;
}
public int quarters(int quarters, int remainingAmount){
return quarters = remainingAmount / 25;

I have eight panels that are one above the other and are the full width of the frame.
I would like to hide some of them some of the time and then "bring them back".
If I use panel1.setVisible(false) panel1 will disappear but then all the panels below it move up to take panel1's place.
I don't want that to happen. I want just a blank area where panel1 was.
Is there a way to do that?

I have a login window, which when sucessful will activate a new Applet/JFrame. The problem is that the login window remains in the background under the new JFrame. I want this to diappear. I want to either set the visibility to false, or close it.This is how the new window is started:
if(sucess.equals("flase")){
DBAccess dba = new DBAccess();
dba.setFname(fnameusr); //fnameusr
dba.setLname(lnameusr); //lnameusr
dba.main(null);
//LogIn.exit(0);

I've a simple status bar in which I've several icons inside a HBox (ui drawn with fxml). These icons can be visibile or hidden due to some configuration properties in my app. I've a bind between some BooleanProperty and image.visibleProperty. The problem, as you can guess, is that when an icon in the middle disappears I've a hole. There is a property as in Android [URL] ...., that hide the node and collapse its space?
