View Repliesusername 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 want to validate username and password in JavaScript. I want to validate username and password with database values. If login failed i want to display alert message...ok. But problem is that i have index.jsp page. After clicking login button control goes to homepage.
jsp..okk.. in index.jsp I have taken dropdown to show designation. I select design then control goes to respective homepage... in homepage. I am checking username and password with database values. If login successful it goes to respective pages but if login failed it has to show me alert message. How can i do that ?
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 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);
[Code] ......
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 ....
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try {
state=conn.createStatement();
res=state.executeQuery("select*from conex");
String pass=new String(this.pass.getPassword());
String name=this.name.getText();

I have created a JSP page, on click of a particular button, the control moves to the servlet "TestServlet".
This is the code under TestServlet:
import java.io.IOException;
import java.io.PrintWriter;
import java.security.Principal;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;

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 have my mapping as below
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>co.edureka.controllers.MainController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
So that I can map the first request coming say www.xyz.net to my first page , it does the work but some of my css and images is not getting displayed .
So I did as below
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>co.edureka.controllers.MainController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
<url-pattern>/first</url-pattern>
</servlet-mapping>
By doing this my css and images get displayed and everything works fine.
But the problem is I want to display my first page as user puts the url.
I am putting my jsp pages in WEB-INF/jsps , I am not putting it directly under WEB-CONTENT directory.

I am working on a little project to create an App that can read contents from a website and return it back to my app. What protocol to use for that. Just the reading/retrieving content from a website.
View Replies View RelatedIs it possible to use java to log on to a website? I mean,Ii know how to connect to a website and send commands, but I am not sure how to tell the server that i want to login?
And then after you logged in is it possible to then do something? like, if you logged in to gmail.com you would be able to see your emails?
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 am currently trying to update a few java applets for a website. As of right now, the applets are automatically blocked on all computers when they are accessed because the newest updates for Java have caused them to be blocked. I have determined that the solution to this is to resign the .jar files that are used to run the application with a new certificate.
I requested and received a certificate (in pkcs 12 format, a .p12 file), imported it into the computer, and used it to sign the .jar files. However, I have been getting an error after signing the .jar files stating that the full certificate chain of the code signing certificate is not valid.
I tried to check the path of the certificate using a method he recommended (using OpenSSL) but didn't really find anything of use.
how would i use it to restrict certain websites to be accessed.

This is probably more of a web-based question. I have a basic web crawler I wrote with Java (using JSoup) which crawls through our repositories and stuff to locate the paths to certain snapshots and whatnot. It crawls through using the file tree which gets exposed when you try to go to a directory in a URL.
The problem I am having is that some of the directories contain index files, which means the connection to the directory redirects from the file tree to the index file. Any way to prevent that redirection?
I have a Java application this application sits on a Dedicated server and gets information about the machine and run commands on the machine.
I need it so that i can run these commands from pressing buttons on a website. For example i press a button to retrieve CPU info, it goes to the app, and the app sends the CPU info back.
I'm fine with the website and app its just the middle bit. How do i get the app to run commands sent from a webpage. Been ratting my brains for a couple weeks now.
I currently have the following code that I use to download a file from a website:
URL website = new URL(imgurl);
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(dir+""+imageNumber + "." + extension);
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
Usually, the code works very well. But sometimes, the download gets stalled indefinitely. Is there a way to set a time out period for the downloading of this file?
I am having a difficult time trying to get results from the code below. The purpose is for my program to insert the DHL tracking number in the tracking text box, and then for the program to "click" the search button and get the tracking results.
This is the code:

import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlInput;
import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;
import java.net.*;
public class DHL {

These are the results I am getting in the console (in red), which look like an error:

I am trying to make a program to go on a stock website find the value a particular stock is at and display it to the user. Then repeat at your selected timeframe.
I can get my code to read the entire source of the page or open a page but I cannot seem to get it to find something within the source.
What It would do when completed. Get input from the user on what stock and sight to search and how often to check it. Once the run button is clicked I would like it to take the input from the user and run in the back ground going on the website searching the stock and display the numbers back to the user. I have only been able to have it display the entire source code though, not just the stock numbers.
