Count External Hyperlinks On Each Page Of Website
Aug 25, 2014
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.

I'm working on a project where I have to take an input text file with terms and create a glossary with hyperlinks. I've got it working halfway. It outputs the html files for some but not all of the terms and I can't figure out why.
I'm getting these errors:
Please enter the location of the input file: data/terms.txt
Please enter the location for the glossary: data/testOutput
Exception in thread "main" java.util.ConcurrentModificationException
at java.util.LinkedList$ListItr.checkForComodification(LinkedList.java:953)
[Code] .....
How would I fix them??
Code :
import java.util.Comparator;
import components.map.Map;
import components.map.Map2;
import components.queue.Queue;
import components.queue.Queue2;
import components.sequence.Sequence;
[Code] ....

I have an array with the following characters {'E', 'L','E','P','H','A','N','T','P','O'}
now, I need an array that will store the first array such that only the occurence occurs e.g {'E','L','P','H','A','N','T','O'} Notice that the characters 'E' and 'P' occur twice and as a result were not repeated the second time in the new array.
How would one go about this using the counting elements technique?
I tried this but not sure how to use the counting elements technique.
char [] arr = new char{'E', 'L','E','P','H','A','N','T','P','O'};
char[] bucket = new char[(arr[0] * arr.length)];
for (int i = 0; i < len; i++)
bucket[arr[i]]++;

I need to build an application that can preform measurements. So I have a measuring device that can be connected through USB (with a rs232 converter aka VCP).The manufacturer provided me with two libraries:
C++ : a library (.lib) file and a header (.h) file
VB6 : a DLL (.dll) file and a list (.txt) with all the available functions
And also some demo code. Can't get the C++ code running with my Borland C++ 5.5 compiler but the VB6 code is working.What can I use to integrate into my java code.

So I prefer to use Emacs rather than using Eclipse or some other IDE and I am wondering how to include external classes in my main file?
For instance I have my main file (the one that includes my 'main()' function) and then I have another class (seperate file(s)) for creating a GUI, or making a game and using a Player class, Weapon class, etc. How can this be done? Do I just use 'extends myclass'?

I am doing a few Spring tutorials and in eclipse and for each tutorial I have to right click my project, build path, and then add external archives and then select the spring JAR files I want to bring in and use before my project will successfully compile and run. I was just wondering is this required for every project or is there a way I can set eclipse up to look in these locations for every project without me having to explicitly tell it too?

I am writing a console application that is to make use of the system editor on *NIX. For that I have written a method which writes a string to a file, launches an editor to change that file, and then reads the file again. The problem is the call to run the editor doesn't wait for that application to have closed.
Java Code: Runtime.getRuntime().exec(editorcmd + " " + tmpfn); mh_sh_highlight_all('java'); I need the program to wait for the editor to have finished.

In our product, we have many different of "roles". Some of these roles are defined in our dataload JSON and others are defined in our bootstrap SQL.
Throughout our code, we refer to specific roles by name. We want to provide some sort of documentation for these roles when we mention them in documentation, but we don't want to maintain multiple definitions/descriptions for these roles (ie: we don't want one for documentation and a separate one for execution).
Any way we can "expose" the role definitions to the documentation? The best thing I've got is adding some sort of "export script" to each generation of the javadocs, but I don't have a clue how, or if, that can even be done...

I want to create a java program to find the applications running in my computer. And then I want to select a particular application called 'Harvest Client.exec'. Bring the application to front. And Then find a textbox in it and paste the things from clipboard.
I am not sure how to do this. I started by using some Runtime methods. But I am not getting anywhere.

I'm currently using TextPad or command prompt to compile and run my programs, and as usual I am not having any luck importing external libraries, in particular apache commons.
I couldn't see any particularly obvious settings in TextPad to set a library or class path (which is annoying as I really like the program), so I jumped back to cmd prompt to run it from there. Aaaaaand i don't understand .
This is my file structure at present:
/mainProject //includes .java and .class files, and where I've successfully placed .jar files before.
The apache commons zip file was extracted here, making:
/mainProject/commons-lang3/apidocs/orgs/apache/commons/<folders> //the commons-lang3 folder contains the jars I'm navigating to the /mainProject folder in cmd prompt and typing (amongst many other things) javac -cp /mainProject/commons-lang3 MonsterGame.java //with the -cp being pointed at the folder the .jar is in i've tried pointing it at the root folder where the import statement begins in the code (ie mainProject/commons-lang3/apidocs), tried moving the .jar files to the mainProject folder (pointing -cp at it) and more. No luck.
it seems everytime i try to import a new library something goes wrong..... its become a bit of a stumbling block to be honest. I seem to spend most of my time dealing with the 'administrative' side of coding (that was the politest way i could put it ), am I not doing it right?
I've read I'm supposed to include the .jar in the classpath, not just the directory. is this correct? (it still doesn't work...!)

I am reading the excellent book Algorithms. The author of this book is using his own libraries.
I have downloaded the libraries (it is a file called stdlib.jar) and I've store it in a directory called ~/Downloads(I am using a macbook pro).
Then I have created a project with IntelliJ Idea 14.1 using the default package (as it is the only way for a program to 'see' these libraries).
The program is running inside the ide, but because of the nature of this book, all the included code must be run from the command line.
The problem is that I cannot run for example the Average class from the command line because the system asks for the external library.
Specifically the error is :
I enter : java -cp . Average
and the Error I get is :
Exception in thread "main" java.lang.NoClassDefFoundError: StdIn
at Average.main(Average.java:11)
Caused by: java.lang.ClassNotFoundException: StdIn
at java.net.URLClassLoader$1.run(URLClassLoader.java:372)
[Code] ....
The Average class is the following :
public class Average {
public static void main(String[] args) {
//Average the numbers on StdIn
double sum = 0.0;
int cnt = 0;
[Code] .....

I've installed the Java JDK onto my Windows 8 laptop and the first thing I need to do is run the compiler from the Command Prompt. The first prompt I enter is C:java -version. This worked fine, however when I try to enter the next prompt C:javac -version, I am getting the following screen and messages:
Microsoft Windows [Version 6.3.9600]
(c) 2013 Microsoft Corporation. All rights reserved.
C:UsersMary>java -version

Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
C:UsersMary>javac -version
'javac' is not recognized as an internal or external command,
operable program or batch file.
I have entered the path into the environment variables area within my control panel. Not too sure why the first prompt works, but the second doesn't...

I have a WebView and a Javascript that appends an <img> tag in a webview.
Like so:
function insertImg(src) {
$("body").append("<img src='" + src + "'/>");
}
I call this function with the following code:
String path = "file://Users/rod/Desktop/123.gif";
webengine.executeScript("insertImg('" + path + "')");
However, this does not work and no image is displayed.
How can this be achieved?

I've constructed 4 different levels and allow the user to select the level they want to play from a central JPanel in a Card Layout system. My problem is that once a level is completed, I can't switch the JPanel which is displayed to start the next level, since I don't know how to access the original JPanel which acts as a driver for the other panels.
MainFrame.java
Java Code: import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.Color;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.Font;
import javax.swing.JButton;
import javax.swing.JFrame;

I am quite new to developing Applets in java. I recently made an applet that will play a particular sound whenever a button is pressed. The sound files are placed in the same directory as the applet class file and i access them by using
AudioClip clip=getAudioClip(getCodeBase(),"A.wav").
The Applet runs fine in the appletviewer but whenever I try to open it using any browser like Chrome,IE,Firefox the applet loads but sound isn't played. I checked the java console and it showed
"java.security.AccessControlException: access denied ".
My questions are:
1. How do I allow the applet to get access to those files?
2. When the Applet is running from the local file system why CAN NOT I access those resources via getCodeBase() ???
3. I googled and found that I can sign a JAR and that can have full access to the computer. But how do I create a JAR from an applet (which has no Main method) while it asks me to point to the main class in the manifest?

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.
