im working on a program, but i have question and its. How can i add a website into one of my "JFrame" i have made?
exampel i want to add google.com website into the fram called V2.
HERE IS MY CODE:
Java Code: package mittprogram;
import java.awt.Color;
import java.awt.Font;
[Code].....
So I have this line of code...
ioexception11.addChoosableFileFilter(new Jframe());
And when I compile it gives me...
error: constructor Jframe in class Jframe cannot be applied to given types;
ioexception11.addChoosableFileFilter(new Jframe());
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.
Am currently developing a website in JSP. For security reasons I need to have an unchanged URL throughout my website. Is there any way to achieve it?

My Questions:
1. Can I use Connector/J to connect to my website database (MySQL)?
2. Which one is better? 1.Connect to website database, 2.Use Socket programming.
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?
The test file is on [URL] ....
Is there a way to tell the login name of a visitor to a website?
View Replies View RelatedI 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.WebClient;
import java.io.*;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.html.HtmlInput;
import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;
import java.net.*;
public class DHL {
[Code]...
These are the results I am getting in the console (in red), which look like an error:
Apr 23, 2015 7:55:49 PM com.gargoylesoftware.htmlunit.javascript.host.html.HTMLElement addbehavior
WARNING: Unimplemented behavior: #default#userdata

at com.gargoylesoftware.htmlunit.html.HtmlPage.getElementByName(HtmlPage.java:1747)

I just cannot figure it out for the life of me. Also, is there a community that focuses on HTML Unit?
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.

i have this code to connect and login to a HTTPS website Now when i run it i get a 500 code error and if i print out the html of the website it says something went wrong. This is the website [URL]
And this is code

import java.io.InputStreamReader;

I have tried to login a website using HtmlUnit but it get an error.
try {
response.setContentType("text/html;charset=UTF-8");
String loginUrl = "h t t ps://www.fshare.vn";
int loginFormNum = 1;
String userName = "LoginForm[email]";
String password = "LoginForm[password]";
[Code] ....
Exception : [URL] ....
So we need to inform all active users of the website that "Website will be down after so and so time for maintenance". This is how I see the implementation.
User can be in any part of the application. So any time user request comes to server, it goes through the controllers. I can write a method (and call from each controller) that checks if message needs to be displayed. Put that into application context and display it. Along with that I will also have a flag that keeps track that if the message has already been displayed or not (to the user). If message has been displayed, no need to call that method again.
This might make me look pretty silly but I was curious if there was a way to make a dynamic web page in java. Basically only using pure Java, with only HTML5, CSS and mySQL.

I am working on a Project of Ecommerce Shopping WebSite in Java.
First I Decided to use Servets,JSP,Spring,hibernate etc.. from Scratch to design its Layouts and Functionality.
But After Reading this Thread [URL]...
I Found that there are already some Ecommerece Solution that are availabale in Java Like Magento.
Is it worth To use these Ecommerce Solution for Development Purpose of Premium Purpose.
I read that some of them are Open Source.
If a ShoppingCart Solution is OpenSource then Can We Use that to develop and Distribute for Premium Purpose?
how we call a jFrame from another jFrame .
View Replies View Relatedfind out why when I access the site for the first time, it loads a blank white page, but when I reload it, it forwards me to the home page as it should.
I doubt that the reason is nothing else than the code below (in the doGet method):
String email = (String) request.getSession().getAttribute("email");
String cookieValue = null;
System.out.println(email);
// first, checking the session
if (email != null) {
request.getRequestDispatcher("/homelogged").forward(request, response);
[code].....
I suppose it's something with the session... because after I reload it, it works. But! When I close the browser and start all over again, the main page is white-blank again... And after a reload it works.
The exception:
SEVERE: Servlet.service() for servlet [first] in context with path [/MYSITE] threw exception
java.lang.NullPointerException
at controller.Controller.doGet(Controller.java:42)
Line 42 of the Controller is "for (int i = 0; i < cookies.length; i++) {"
P.S. I cleared all the cookies, but the problem persists.Also, the first it loads, it prints in console:
"null
been here 4!"
But, if I reload further, it prints:
"null
been here 4!
been here 2!
No Email! Literally, doGet!"

I need to count external hyperlinks to other web-sites on each page of the the web-site. I've found this code here on stackoverflow:
public class Scanner {
private HtmlProcessor hp;
private String baseUrl;
private int step = 0;
private List parsedLinks;
public Scanner(String baseUrl) {
[Code] .....
Also I've found other working code that uses standard Java but it counts links only in one web-page. Can't create pattern to look all pages on web-site yet.
