TLS / SSL HandshakeException - Invalid Padding Length

Apr 22, 2015

I'm trying to establish an SSL connection (using a self-signed certificate). However, I can't seem to get the handshake to work. At the moment server side, I've created the public/private key + signed certificate and then stored them in a KeyStore. I've also stored this signed certificate in a KeyStore (trustStore) client side, so it can compare.

Keys: RSA, Certificate Sig: SHA256withRSA, cipherSuite: TLS_RSA_WITH_AES_128_CBC_SHA

Client Code

// 34393570706261
SSLContext context = SSLContext.getInstance("TLS");

TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(client_trustStore);
context.init(null, tmf.getTrustManagers(), new SecureRandom());
SSLSocketFactory socketFactory = context.getSocketFactory();
conn = (SSLSocket) socketFactory.createSocket("localhost", port);
String[] suites = new String[]{"TLS_RSA_WITH_AES_128_CBC_SHA"};
conn.setEnabledCipherSuites(suites);

[Code] ....

BufferedImage Has White Padding On Top?

Jul 27, 2014

What I am doing is loading a new image from resources in my project, so that I can get the size. Using this, I create a new BufferedImage with those dimensions. The following code is what I am using to take the original BufferedImage, and scale it.

Java Code:

public ImageIcon getBackImage(){
before = new BufferedImage((int)img.getWidth(null), (int)img.getHeight(null), BufferedImage.TYPE_INT_ARGB);
int w = before.getWidth();
int h = before.getHeight();
try{
URL url = getClass().getResource("/Blue_Back.png");
before = ImageIO.read(url);

[Code] ......

The scaling seems to be working fine, but what I have noticed is a line of approximately 10 pixels at the top of the image. I took the original image and blew it up to ensure that I wasn't just enlarging undesired portions and this wasn't the case. I then tried to fetch a subImage of the BufferedImage, and that also left the padding at the top. Is there something I am missing that is placing this undesired padding at the top of my bufferedImages ?

Padding Will NOT Work - Adding Spaces?

Apr 22, 2014

Why this will not pad?? It keeps displaying normally, even if i add spaces it will not work.

System.out.printf("%-20s%-20s%-20s%-20s", p.getLastName(),
p.getLastName(), p.getSocialSecurityNumber(),p.getAge());
This is what it is printing:

=================== =================== ====================== ===
lastname, firstname, 123-12-1234, 16

The lastname, firstname, 123-12-1234, 16 should be padded and appear with about 20 spaces between them.

Error - Invalid Float Literal

Apr 26, 2014

While doing trial and error got caught in the below scenario.

public class Crypt {
public static void main (String args[])
{
/*all I want is calculate a binary number (ex -: 22 , 34) using decimal base (10n).
*So, I have to convert 2 p into 10n form so I have to find n in terms of p . We have x as the input.
* The formula works as below.
*2p =10n
*p ln (2) =n ln (10)
*n = p [ln(2) / ln(10)]
*2 p = 10 p [ln(2) / ln(10)]

JavaFX 2.0 :: MediaPlayer Error - Media Invalid

Jul 11, 2014

I am having a problem with the JavaFX MediaPlayer playing videos with resolutions greater than 1920x1080px. For testing purpose I downloaded the example from [URL] ... and added the following error-handling:

mediaPlayer.setOnError(new Runnable) {
     @Override
     public void run() {
          System.out.println(mediaPlayer.getError.getMessage());
          System.out.println(mediaPlayer.getError.getType());
     }
});
 
When playing a video with a resolution of 1920x1168px, the window became black and I get this console output:

[com.sun.media.jfxmediaimpl.platform.gstreamer.GSTMediaPlayer@5482fb8f] ERROR_MEDIA_INVALID: ERROR_MEDIA_INVALIDUNKNOWN

The video is encoded with h264 and aac (for audio) and is having a resolution of 1920x1168px. The error occurs with each video with a resolution greater than 1920x1080px. Vidoes with a resolution of 1920x1080px or smalle are working fine. The playback of all videos is working with VLC-Player. I tried Java 7_51 and Java 8_5.

JavaFX 2.0 :: Invalid Transform On Shape After Creation

Jan 21, 2015

I am working on a UI in JavaFX and create several instances of a custom control class. The control consists of a Pane which wraps several other containers, one of which contains a Circle shape.
 
At one point, I instance this control and access the Circle shape directly. I transform it's center coordinates (which are always {0.0, 0.0} ) to Scene coordinates.  The problem is, the transformation always yields coordinates that correspond to the upper left corner of the control's root pane.
 
In other words, it's as if the Circle is positioned at the upper left corner of the custom control (when, in fact, it's positioned near the lower right corner).
 
I have other instanced controls already in the scene, and they do not have this issue - converting the Circle's coordinates to scene coordinates works as it should.
 
It seems obvious that I'm accessing the Circle too soon - that perhaps the scene graph hasn't been fully traversed for the control and the Circle's position within the control's hierarchy hasn't been updated.  I've verified that my attempt to access the Circle's center coordinates occurs after the control's initialize() method is executed, so how to ensure the control's scene graph has been fully updated before I try to manipulate the control...

Count Length Of Each Word In A String

Aug 5, 2014

I am looking for a way to create a method with the initial state in while loop, which will count the length of each word in a string using I want the output to be something along the lines of:

hello world how are you
There are 0 words of length 0
There are 0 words of length 1
There are 0 words of length 2
There are 3 words of length 3
There are 0 words of length 4
There are 2 words of length 5

This is my code so far it sort of does the job but not the way i want it too

import java.util.Scanner;
import java.util.StringTokenizer;
public class Brown_Matthew_13117002{
public static int count(String s, int len){
int result=0;
StringTokenizer st=new StringTokenizer(s,"[ ,;]");

[Code] ....

The output would end up being :

hello
There are 0 words of length 0
world
There are 0 words of length 1
how
There are 0 words of length 2
are
There are 3 words of length 3
you
There are 0 words of length 4

Finding String Length Without Variables

Oct 14, 2014

The problem asks me to write an expression whose value is the number of characters in a specific string. Normally, it would be a simple task of using the String.length() method, but that is not allowed. In fact, no variable declaration is allowed (it's a MyProgrammingLab assignment, if any are familiar).

Simply put, if I have a String "This is a sample string." is it possible to find the length without assigning it to anything?

In other words, the code must be able to go into the parentheses of System.out.println( ); and correctly print the length of said string.

The answer, for those curious:

System.out.println("This is a sample string.".length());

I didn't know the .length() method could be called on a literal. Now if only I could find out how to close this thread...

How To Test For Array Length Equal To Zero

Mar 15, 2015

I am working on an assignment covering exception handling and am stuck on part of the assignment. How can you test for array length = 0?

When I try something like: if (array.length == 0) on a null array, naturally I get a NullPointerException. I would try something like if (array != null) but both array length of 0 and null array are supposed to throw different expressions.

Stuck On Average Word Length

Aug 1, 2014

The goal of this code was to create a program using main method java to analysis a piece text which has been entered from a user.

They do this by entering the text into a scanner which is then analysed by the program. The analysis is to produce word frequency, for example " This is a test" produces this results:

This is a test

1 letter words: 1
2 letter words: 1
3 letter words: 0
4 letter words: 2
5 letter words: 0

The bit that I'm stuck on is producing a mean/average, My mind telling to divide

counts.length
by
str.length

But I'm not the Best at java and I've tried to implement this but all I get are errors.

Code:

import java.util.Scanner;
public class While_Loop {
public static void main (String[] args) {
while(true){
