Java Module Issues

Hey I am making a game in java using slick and run into all these errors. It works on my friend's computer but not on mine. I've tried on both mac and pc.

What does above exception mean??
I do have it in my class path.

The error message explains it all, you dont have a LWJGL on your classpath. You need to install it so as to get it working on your system.
Also you need to point the jvm to the location where the native files are located using a command line parameter -Djava.library.path="path/to/natives". JarSplice is an alternative to this
You may check this for details

The lwgjl native library cannot be found and loaded. Set the path to the folder where lwjgl.dll (if on Windows, on Mac probably liblwjgl.so) is located, with -D, for instance
java -Djava.library.path=C:\Java\ljwgl\libs com.mypackage.MyProgram
The library files must have a permission to be executed. Some computers may be configured to suppress any execution from USB stick so check.
If still does not work, try to call System.load(String fullFilePath) from your code, pointing to the location where the file clearly exists. If this works at the end, you can use this function to load library without name alterations and path assumptions. If does not, it may be wrong achitecture (64 vs 32 bit, permission problems (not executable) or the library file is just broken.

JavaCV-OpenCV error

I want to capture my webcam on a easy way into Java.
I followed this tutorial with JavaCV and OpenCV: http://ganeshtiwaridotcomdotnp.blogspot.com/2011/12/opencv-javacv-eclipse-project.html
I get this error when trying some example code:

But al my jar's are included, Microsoft Visual C++ 2010 Redistributable Package is installed, extracted OpenCV into root and my system Path is set correct... (tryed already several times to reinstal the Visual C++ Redistributable Package). (x64 bit, does it matter Netbeans is x86?)
Or does anybody know an other lib that easily captures a cam in java?
Thanks a lot!

I am the one who wrote the tutorial that you're following.
Exception in thread "main" java.lang.UnsatisfiedLinkError:
C:\Users\Francis\AppData\Local\Temp\jniopencv_core7109340164936655704.dll:
Can't find dependent libraries
It looks like the dll library is not in environment variable path because you didn't properly added the path of opencv. Or this might be issue because you have installed both x64 and x86 version of thet Visual C++ redistribuables that Romain is saying.
I suggest you to follow the steps I described here JavaCV : eclipse project configuration windows ? and Add the following to System Path ?
Configure path
64-bit version of the JDK:
[installation path]\build\common\tbb\intel64\vc10\;C:\opencv\build\x64\vc10\bin\;
32-bit version of the JDK:
[installation path]\build\common\tbb\ia32\vc10\;C:\opencv\build\x86\vc10\bin\;
Here [installation path] might be "C:\opencv"
Hope this helps.
UPDATE:
An easier and simpler step to configure JavaCV is available. Please check the link below:

Javacv UnsatisfiedLinkError in windows 7

In my project I want to capture image from my webcam.
I configured step by step following the instructions from this "OpenCV-JavaCV : eclipse project configuration windows 7" blog post.
After configuration is finished, i tested samples codes and the application found my webcam
SETUP: Setting up device 0
SETUP: Namuga 1.3M Webcam
SETUP: Couldn't find preview pin using SmartTee
SETUP: Capture callback set
SETUP: Device is setup and ready to capture.
and then i got an error which is .dll error.
I use windows 7 x64.

How can i solve this problem?

Check whether your Opencv version and JavaCv versions are matching each other. You can check that on the readme file on javacv-bin it specifically say about the required version of the opencv.

Unsatisfied link means that not all native code libraries required by jniopencv_core.dll could be found.
Did you deploy them all or just jniopencv_core.dll?

I faced this problem on Windows XP and Windows 7, and this is how I fixed it on both platforms, using Netbeans 7.2:
Install all required software:
FFmpeg (32-bit shared): Zeranoe FFmpeg offers win32 builds. Download and extract ffmpeg-20121020-git-04bf2e7-win32-shared.7z. Place its content at C:\ffmpeg.
Note: make sure C:\ffmpeg\bin is a valid path.
OpenCV 2.4.2 (32-bit): download OpenCV-2.4.2.exe and extract it. Place its content at C:\opencv.
Note: make sure C:\opencv\build\x86\vc10\bin is valid path.
JavaCV 0.2: download javacv-0.2-bin.zip and extract it. Move the extracted folder to C:\javacv-bin.
Microsoft Visual C++ redistributable package (32-bit): download and install vcredist_x86.exe.
Configure the environment:
Edit the environment variable PATH and append the following paths at the end:
C:\ffmpeg\bin;C:\opencv\build\x86\vc10\bin
Now you ready to create a new Netbeans project and test your application. But before you compile it,dDon't forget to right-click the Libraries folder at the pProjects window* and click Add Jar/FOLDER to select all the .jar files located at C:\javacv-bin.

Make sure you have the vm arg -Djava.library.path=<path-to-native> that points to the directory with your dlls.

What files does JDIC need to run?

I'm trying to call JDIC from my application, but I can't get it to run. What files do I need and where? From what I've been able to gather from their site, I basically need to put jdic.jar in classpath... however there is also a lib folder with jdic.jar with a bit different size, and jdic_native_applet.jar, jdic_stub_unix.jar, jdic_stub_windows.jar and several folders with what I gather are platform specific files.
I get this exception when instantiating AssociationService:
java.lang.ClassNotFoundException: org.jdesktop.jdic.filetypes.internal.AppAssociationReaderFactory_windows

at QuickTest.main(QuickTest.java:101)
I've tried last "official" release and last alpha release. I'm running Java 6 and Win7 64bit. Does JDIC even work under Win7 (or 64bit, although I use 32bit Java)? I see no release after 2006, and no activity in the project after about 2008... while Win7 came in 2009.
I know that parts of JDIC, like Desktop, were included in Java 6, however that doesn't seem to be the case with file associations.
And if it doesn't, are there any (hopefully cross-platform) alternatives for managing file associations? There are some things for Windows only that I tried, but that requires running native commands with administrator privileges which I don't know how to pull, apart from asking user to run my app as administrator and then use Runtime.exec()...
If there are no alternatives to JDIC, I'm interested if anyone has managed to handle file associations well with cross-platform installers?
UPDATE: OK, figured part of it... everything from windows folder needs to be in root folder. However now I get this exception which brings me back to my original question:

Can you recheck the java you are using to run this? The error typically occurs when trying to load a 32-bit dll from a 64-bit java. jdic does work for us on 64-bit Windows 7 with 32-bit java.

JavaMail ClassNotFound

I've run in to a strange error with the javamail 1.4.2 api and jdk/jre 1.6.0u16. I've placed the unzipped javamail-1.4.2 folder (along with the MySQL Connector-J 5.1.7 also needed) in both the jdk and jre folders as in the %classpath% below.
.;"C:\Program
Files\Java\jdk1.6.0-16\jre\lib\ext\mysql-connector-java-5.1.7-bin";"C:\Program Files\Java\jdk1.6.0-16\jre\lib\ext\javamail-1.4.2\mail.jar";"C:\Program

Files\Java\jre6\lib\ext\mysql-connector-java-5.1.7-bin";"C:\Program Files\Java\jre6\lib\ext\javamail-1.4.2\mail.jar";
But when I run my compiled jar with the command
C:\Program Files\Java\jre6\bin>java -cp %classpath% -jar "C:\Program Files\GameLabInventory\GameLabInventory_7.0.jar"
I get the following error message:

I can't find anything wrong with my setup here, hopefully you guys can help me out. Thanks!
Here is the manifest file:
Manifest-Version: 1.0
Main-Class: gamelab.inventory.GameLabInventory
Here is the jar -tvf (link)

According to the documentation for the java tool:
When you use [the -jar] option, the
JAR file is the source of all user
classes, and other user class path
settings are ignored.
You can specify a Class-Path attribute in yourJAR file that "specifies the relative URLs of the extensions or libraries that [your] application or extension needs."

When using -jar, java overrides the classpath setting (-cp). In this configuration, however, classpath jars can be specified in the manifest file of your jar.

I've experienced a similar issue (not identical to yours, since mine is spring-related) and found this link was helpful:
http://forum.springsource.org/showthread.php?t=65840&page=3
It seems that implementation changes in the JDK might be causing this behaviour. Quoting from the link:
"I managed to reproduce the problem on my Mac development box using Java 6 (1.6.0_07). I then tried it on my Mac using Java 5, and could not reproduce the problem. Crucially, in the Java 5 case, the JVM would be using the javax.activation API and implementation from the 1.1.1 javax activation bundle, whereas on Java 6, it would be using them from the JRE (anything that's part of the JRE takes precedence over what's in dm Server's lib directory). I then tried the app on an Ubuntu box, this time using Java 6 1.6.0_10. I could not reproduce the problem."
and/but:-
"I've just had this same problem "No object DCH for MIME type" but on Ubuntu java version "1.6.0_13". So I don't know how you guys solved it by upgrading to 1.6.0_11.
What I did is copy the mailcab.default to my own bundle and it worked. Seems to be a classloading problem which I don't fully understand yet."
