Slick2D Runnable Jar Not Running (Unsatisfied Link Error)
May 3, 2014
When I try to run my runnable jar file, it wont do anything. And when I try to run it from the console, it says
"java.lang.UnsatisfiedLinkError: no LWJGL in java.library.path..."
How do I fix this?
I've specified the path by properties > Libraries > lwjgl.jar > Native Library Location > .... And I chose the right paths. But I still get that java.lang.UnsatisfiedLinkError.
It says I'm getting an error on line 34 which is:
appgc = new AppGameContainer(new Game(gamename));
My whole main class is:
package net.battleboy;
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
public class Game extends StateBasedGame {
public static final String gamename = "Battle Boy 1.0 ALPHA";
public static final int menu = 0;
public static final int play = 1;
public static final int settings = 2;
[Code] .....

I've seen examples that don't use a separate Runnable Implementation, but Instead Just make a subclass of Thread and override the Thread's runO method. That way,you call the Thread's no--arg constructor when you make the new thread;
Thread t = new Thread(); 1/no Runnable"
Any simple code that demonstrates the same. I haven't fully understood what is said in the text above. I have a hunch that the last line is wrong and it should be Thread t = new <Whatever class extends Thread class and over rides its run method>()
Am I correct or wrong....

I am still working on my java course and now we have to create a jar file from a previous project (this is a project where a connection to the database is made and data is shown in a frame).
When I follow the instruction in my course material I don't get it to work. I've tried the following:
1. Open eclipse on windows xp
2. Right click on the project folder in eclipse
3. Click on "export" in the menu that appears
4. Choose "runnable jar"
5. click next
6. I insert the following parameters:
- Launch configuration --> I select my main class
- export destination --> I select the folder D:
- library handling --> Package required libraries into generated jar
7. click Finish
This is what happens when I dbl click the jarfile (wampserver is running):
1. I get an error: "SQL ERROR: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server."
2. I click ok on the message and the following message appears: "SQL Error: null"
3. I click ok on this message and the frame with the fields appears without data from the database.
This is a crosspost to: [URL] ...

my aim is to make a runnable jar. I've made a program using swings which uses MS Access database to fetch records. So, I've used an absolute path to refer to the database for connection. Now, I intend to distribute this runnable jar to other people as well. So I guess the best option would be to embed the MS Access database as well in the jar file. But I don't know how to do that. Where should I keep the database in my Project Explorer ? Should I use a relative path etc.
This is my code:-
Java Code:
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
import java.util.Vector;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
[code]....

I want to have two threads running in my class, one will be downloading info from a website then putting the thread to sleep for a little bit, then repeating. The other will be sending information to a website then putting the thread to sleep for a little bit, then repeating. Is it possible to do this in my main class? I already have one thread using run() for downloading the info and sleeping can i make another?

I recently started working with Java 8. I have been doing Java development on and off since the early 1990's. Most recently I have been doing all my current work in Java 6. I decided to "take the plunge" and to start getting involved with Java 8. I have an imaging application for geologic research I started working on in Java 6 and Swing, and I am now continuing that development under Java 8. It was a pleasant surprise that to find that all of my code built without any changes (I'm using Eclipse Luna and just deleted the Java 6 runtime and added the Java 8 runtime after downloading it). The application launches fine from inside Eclipse.
However I ran into a problem when exporting the application from Eclipse to a runnable JAR file and then trying to launch it. After creating the runnable JAR I was not able to launch it by simply double clicking. A command line box would open for a second, then close and the application window would never open. To upgrade from Java 6 to Java 8 I only downloaded the Java 8 runtime environment, not the Java 8 JDK. I am working in Windows 7 and tried updating the JAR file associations and experimented with various path entries in my environment variables. No mater what I did I could not simply double click the runnable JAR to launch it.
Then I deleted all my Java downloads and started over. This time all I did was downloaded the Java 8 JDK and installed it. I then pointed Eclipse to the Java 8 runtime environment that was installed with the Java 8 JDK. My code built and executed perfectly in the Eclipse environment. Then I exported the the Eclipse project as a runnable JAR again and tried to launch it. This time it worked as expected. Double clicking the runnable JAR launched the application!
So my question is if I want to give this application to someone to run (i.e. deploy it) that is not a developer, do I have to have them install the Java 8 JDK? I assumed that all someone would need to run the application as a runnable JAR is the Java 8 runtime environment, not the JDK. However, when I had only the Java 8 runtime environment installed I could not launch the runnable JAR. With the Java 8 JDK I was able to run the runnable JAR as expected, with no problem.

I'm reading about threads In Head First Java and the way an Instance of a class that Implements Runnable Is created confuses me a little.
public class MyRunnable implements Runnable ......
Runnable ThreadJob = new MyRunnable();
I thought I had to use this syntax :
MyRunnable ThreadJob =new MyRunnable();

I'm trying to export a runnable jar file that requires lwjgl. Everything works in eclipse as I'm using
-Djava.library.path=nativewindows
as a VM Argument for the jinput .dll files.
After exporting & launching the jar it doesn't work of course! I get this error:
java.lang.UnsatisfiedLinkError: no junput-dx8 in java.library.path
I'm not sure how to make it work outside of eclipse....

I've been working quite a bit with a login system the past couple of months and I now have a version that I would like to try "for real" by extracting it as a runnable .jar or .exe file. I've looked at a couple of guides that told me how to do this properly, but even after following every step precisely it didn't work.
One of the guides I tried: 3 Ways to Create an Executable File from Eclipse - wikiHow
Double clicking the file or selecting it and pressing enter does nothing, the computer loads for a second and then nothing happens. I don't receive any visible errors when extracting the program, either.
However, when running the file from the command prompt I do receive an odd error:
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.
C:UsersUserName>java -jar Login.jar
Exception in thread "main" java.lang.IllegalArgumentException: input == null!

at LoginSystem.Data.updateData(Data.java:347)
at LoginSystem.Data.<init>(Data.java:309)
at LoginSystem.MainFrame.<init>(MainFrame.java:42)
at LoginSystem.MainFrame.main(MainFrame.java:457)
C:UsersUserName>
I must say I don't quite understand the error, it seems to be unable to load an image which is odd considering the program works fine without any errors at all in Eclipse.

i have tried moving the
//create line
Point beginOfLine = new Point(point1, point2);
//ask user for second pair of coordinates
System.out.print("Enter the coordinates for X2 or <Random> or <Exit>:");
userInput=keyboard.nextLine();
code part to another class but nothing..this is what a second class should be doing
1 - Write a java class called Point to represent a 2-D point (With x and y)
- The constructor should take the x & y as double
- The class should have accessor / mutator methods for all coordinates
2 - Write a java class called Line to represent a line (with a starting point and an ending point)
- The constructor arguments are the start and end points
//import utilities to be used in the program
import java.util.Scanner;
import java.util.Random;
public class Point {
//declare variables
private double pointX, difX;
private double pointY, difY;
