I am running the this from a Linux command line , in the cmd first i use :

I know the problem is from the RandomGenerator class in packet acm.util.* but i dont know how to fix the problem . Every other program has worked . What I am missing or how this whole issue of packet importing works when running a java file from cmd ?
I want to find information about running sudo commands from java, but without gksudo/kdesudo.
This is my code. It works, but after removal "sudo" element.

I wrote some java applications on my computer, which is 32-bit Ubuntu 12.04 LTS. Could the application run on both 32-bit and 64-bit versions of linux? Or could it only run on 32-bit versions of linux?
System.out.println(System.getProperty("sun.arch.da ta.model")); // outputs 32
I would like to know if I run it on a 64-bit version of linux if it will take advantage of the performance advantages of 64 bits.

I'm running a jar of an application and library jars from lwjgl. I'm creating a java process. It's working on Windows but not on linux.
I tried replacing the semicolons with colons but it didn't work, it just said "Main class not found: Application.natives.linux" or something like that. gamePath is the path the application is in. osName is the name of the operating system.
Here's my code:
String jarRunner = String.format("java -Djava.library.path="%snatives/" + osName + "" -cp "%sjar/lwjgl.jar;%sjar/lwjgl_util.jar;%sjar/jinput.jar;%sjar/slick.jar;%sApplication.jar" main.Main", gamePath, gamePath, gamePath, gamePath, gamePath, gamePath);

How can I make it work on linux?
After a transition of an object the UI is not fully updated. One can still see "lines" from the "movement". This only happens on Linux (Debian) and not on Windows. Is this a known issue that has been fixed in later Javafx releases ? I am still using Java7 because of WinXP support

Visual effects such as Transitions perform very poor on linux "wheezy" compared to windows. I noticed this on different PC's, checked for Java7 and Java8. If the UI contains many objects then the transition sometimes does not even appear.

I've tried a few different editors, like CKEditor and TinyMCE, but I seem to run into the same problem with every one. The text area seems to be disabled in a modalPanel. Everything looks like it displays properly, but the blinking cursor doesn't show up and you can't enter any text. Below is an example of the a4j:form that I use in the modalPanel with TinyMCE. why I wouldn't be able to enter any text into the editor? Is there a different editor that will work better?

I am working on a game engine with java. I have come to the final stages of the development of this engine now and need a small hand. For this i am using java's built in libary for graphics. and am strugling to create a nice looking GUi with it, What i need:
The class extends the canvas class and adds it to the jframe, i have set the window up as standard and added a menubar, and net the canvas, what I want to do.
For those of you that have used application such as tiled (shown here [URL] .....) what i am wanting to do is create a gui around the canvas similar to this where the parts on the right are resizable up and down and in and out. i was wondering how i would go about incorporating this.
I am starting a project of a little game for my brother and I wanted to know whether a few things were possible using Java (I know the basics and am currently learning more, but I have about a year to complete this so I have time to learn what is needed).What I need to be able to do:Be able to view a PDF as well as zoom in and pan around itBe able to enter/edit text in said PDF fileBe able to hide some of the text in this PDFBe able to do this on several PDFs in one program (They won't be open at the same time)
Is it possible to do this in Java? If so, how? (As in, what things would I need to learn or what would I need to complete it)If it makes my question easier, what it will be is a London Underground Tube Map (Which is a PDF file)where some station names disappear and the player has to guess which station(s) are missing.

I'm having a problem with a small text editor I'm trying to create. I have implemented a panel of labels, containing line numbers, on the left of a scrollable text area. The panel is designed to size such that it fits the larger numbers whenever they appear. It does that very well, actually, until either one of the scrollbars appear. As soon as one does appear, it immediately shrinks in width. The horizontal scrollbar even blocks the view a little, making it impossible to see what you are writing on the very last line.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Main implements KeyListener {
public static JPanel tab = new JPanel(false);
public static JTextArea text = new JTextArea();
public static JScrollPane scroll, reflex;
public static JPanel lines;
[code]...
Explanation of the code: There is a main panel which embodies a text area and another container filled with labels of line numbers.Both the text area and line number panel have scroll panels attached. They are synchronized, in order to scroll at the same time.
The main class contains a static function "position" which generates a GridBagConstraints, created for the convenience of single-line creation of constraints.It also implements the KeyListener interface, and waits for change in the amount of lines inside the text area. Afterwards, it changes the panel of labels accordingly.

I have a Linux Server Debian 7 x86_64 Minimal With java version "1.7.0_65" installed..Its an online Game Server wich Players can join just like other Services.Every 10 - 15 minutes all the players get kicked from the server and get this messege: "internal exception: java.io.ioexception: an existing connection was forcibly closed by remote host"
The players can't join the server for 10 seconds and the server console doesn't show anything for 10 seconds.it doesnt show that the players even left! and when the players try to join they get htis messege: "same nick is already playing"
After 10 seconds everything will work and players can join again and server console say that everyone left and joined..But that happens again after 10 minutes and im losing lots of players because of this error.
I am trying to set the font of the editor as the same for the renderer of JTable. I am just a bit confused on how to do this. I don't want any code but maybe a walkthrough on what to do. Here is my abstract table model ....

I want to create a jsp where there is a textbox and the user can change font styles (such as bold, italicized, underline, change color, change font style, highlight align a word/s) inside the textbox just like an MS Word. I'm not looking for a system similar to code ranch's posting of message which displays the tag in a textbox...
View Replies View RelatedI'm using [URL] ....., I'm quite surprise of the fact that there isn't a property for the text value. So you can't bind this component to the model.
Why in our opinion there isn't a property to bind (as in other components)?
I'm trying to program a tile-based map editor and most of it is going quite smoothly except trying to organize the layout. Originally I was going to use 2 frames, one for the map, and 1 for the tile set, but after reading about frames I learned that that is bad practice and is also inconvenient because there is no way to have both frames in focus at once (so you need to click an extra time to gain focus when switching windows). So what I'd like to do is create a single frame application that holds 3 panels. One for the map, one for the tile set, and one for tile settings. This is basically what it would look like:
Note that the tile settings panel uses GUI elements (a border, a JLabel (which starts out empty), a JComboBox, and a JTextField) while the other 2 panels are just drawing panels*
Now I have tried multiple things which either did not work visually (panels were inside panels) or did not compile. One thing I tried was using BoxLayout to put the 2 tile panels vertically within a temporary panel which I then tried to add into the frame after the map panel (with FlowLayout), but that made it look like this: I honestly don't know what else I did that I should write here because in retrospect many of the tings I tried were silly or I don't remember exactly what I did. What would be the best layout to doing what I want?
