App Works Locally But Not From Website
Feb 9, 2014
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] ....

I copied this right out of oracle almost. And yet it won't draw.
ImageIcon salt = createImageIcon("icons/bathsalts.jpg");
/**
* @Override
*/
public void draw(Graphics g){
Graphics2D g2d = (Graphics2D) g;
g2d.drawImage(salt, getX(), getY(), null);
}
why draw image doesnt work for me. drawRect and circle are going just fine...
protected static ImageIcon createImageIcon(String path) {
try{
java.net.URL imgURL = ButtonPanel.class.getResource(path);
return new ImageIcon(imgURL);
} catch(RuntimeException e) {
System.out.println("Invalid file path");
}
return null;
}

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("#.###");

import java.awt.Rectangle;
import com.cjburkey.games.boxee.GameState;
import com.cjburkey.games.boxee.resources.Images;
public class Block extends Rectangle {

In the constructor, it returns corrent numbers, in the draw method, it returns 0. Why?

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:

13:01:26.334898 IP (tos 0x0, ttl 64, id 51559, offset 0, flags [DF], proto TCP (6), length 665)
10.0.17.2.3820 > 10.0.17.2.48524: Flags [P.], cksum 0x388f (incorrect -> 0x626d), seq 1085:1698, ack 756, win 273, options [nop,nop,TS val 347297977 ecr 347297976], length 613

I am encountering a problem while running this small piece of code.
public class TestSplit{
public static void main(String[] args){
String myWords[]="My.Home.Is.Being.Painted".split(".");
for(int i=0;i<myWords.length;i++)
System.out.println(myWords[i]+" ");
}
}
The problem is: it does not run at all. No error message is displayed. It just returns to the command prompt when i run it. Where am i wrong?

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:
package testxychart;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
[Code] ....
I think, when I use several graphs in one JavaFX Panel, this will becomes a big problem.

If you write
byte b = 100; it works (implicit conversion of implicit int literal 100 to byte.
But if you have a methodvoid bla(byte b){}
And want to invoke it with a literal (which is an int by default):bla(8) then there is no implicit conversion.
Is the byte b = 100; just an exception in Java? And is it the rule that one has to explicitely cast (narrow) integer literals when passing to smaller-than-int types?

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.

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 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.
