OpenCV java project runs in Eclipse but not in Command line

I downloaded OpenCV for Java and added the jar and libraries to the project in Eclipse and it works fine.
But when I try to run the .class file where my main(String args[]) is, it throws
> java MainActivity 1 5 8
Exception in thread "main" java.lang.NoClassDefFoundError: org/opencv/core/Core

It crashes on this line
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
Is there any way to include the .jar file in the project so it will run from the command line?
Thanks in advance

When you run within Eclipse, then the IDE will automatically handle the dependencies, but when you run from the commadnd line, then you need you to handle it your self.
Follow these commands to do so:
When compiling:
javac -cp path/to/opencv.jar YourProgram.java
When running:
java -cp path/to/opencv.jar:. -Djava.library.path=path/to/opencv.dll
YourProgram
And you can add the .dll path to the system path, then it will automatically get access to it.

NoClassDefFoundError using bluetooth in java

I asked a question earlier here: NoClassDefFoundError with bluecove's javax.microedition
but got no responses.
I am trying to run some java code (Server.java) that requires bluetooth, so I installed the bluecove-2.1.0.jar file in C:\Program Files\Java.
I compile my code with javac -cp "C:\Program Files\Java\bluecove-2.1.0.jar";. Server.java and run it with java Server -cp "C:\Program Files\Java\bluecove-2.1.0.jar"
It compiles successfully, but when I run it, I get the error:
Error: A JNI error has occurred, please check your installation and try again

Any ideas where i've gone wrong?
EDIT: Following Minus' answer, to fix the error that followed, I also needed to use a different .jar file which I downloaded from http://snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/2.1.1-SNAPSHOT.63/

The problem is that the .dll is not loaded correctly.
The library should contain a .dll that will be saved on disk and loaded, maybe the program cannot save the .dll to disk or cannot read it.
Extract the .dll and follow bluecove installation instructions on Native Library location.
For example:
Create a directory c:\blue, and a directory blue\lib.
Put the files like this:
C:\blue\Sever.java
C:\blue\Sever.class
C:\blue\[bluecove_native_library].dll
C:\blue\lib\bluecove-2.1.0.jar
Open a cmd (Command Prompt) on c:\blue
Try to run the app like this:
java -cp .;lib\bluecove-2.1.0.jar -Dbluecove.native.resource=false Server
This way you will have both Server.class and bluecove-2.1.0.jar in classpath and the DLL in path (since on Windows the current dir is in path).

Add a current folder to a classpath (.;) and make sure that your code is in a package-name folder.
So if your server has a package name :
mypackage
make sure that your class code is in a /mypackage directory
than go to a parent folder to /mypackage and call:
java -cp ".;C:\Program Files\Java\bluecove-2.1.0.jar" mypackage.Server

Problems running java classfile from the folder

I have three source files in a folder. I simply want to compile them using commandline and then execute them. However, I'm having the following issue. I am on a windows box:
Code compiles fine:
C:\mycode\src\code>javac Source1.java Source2.java Source3.java
Does not run from the folder where class files are:
C:\mycode\src\deckofcards>java Source1

Could not find the main class: Source1. Program will exit.
However, it does run when moving to parent folder:
C:\mycode\src\code>cd ..
C:\mycode\src>java code/Source1
Hello1
Hello2
Hello3...
......
....
I want to distribute this source to someone and I'm not sure whether they will be on windows or unix box.
Eventually I want to create an executable jar file but that also was giving me an error like this.

Problem here is not with running Java files, it runs fine. So you wanted to understand the following:
In order to run a Java program you need to do the following steps:
Create Java source files (*.java files)
Compile using javac to binary class files (*.class files)
Run the class files using java executable
We use package structure to keep organize the java files. In your case it is a simple application (and you use the package named "code"), but in a large production application we need to organize our code into many packages.
While running the class file, we need to give the class file path (which includes the package path). So in your case you need to execute java code/Source1 to run your class.
You can learn more from this link: http://docs.oracle.com/javase/tutorial/getStarted/cupojava/win32.html
For creating a JAR file you can refer the link: http://docs.oracle.com/javase/tutorial/deployment/jar/build.html
For making a JAR file executable ensure you add manifest file with main-class attribute.

Java - Library path error

I'm trying to start my java game but I have some troubles with the java command line:
Here is what I type:
C:\>java -Djava.library.path=%cd%\lib -jar game.jar
And here is what I got:

I can start my game with Eclipse (With Run as Java Application) but after the menu I got the following error:

lwjgl.jar has been put into the folder \lib.
Could you explain me with I got that?
Thanks.

This because lwjgl library is made by two components:
the .jar file which contains Java code
and the native binary library (which can be .so or .dll or .dylib according to your OS)
The first error you are getting is because you are setting the library path, that should contain the native library, but it does contain the .jar. So you get a java.lang.NoClassDefFoundError because you should set either the library path to the folder that contains native library, either the classpath to contain the real lwjgl.jar file.
The second error that you get with Eclipse is a successive step: your classpath contains the jar library but it is not able to find the native library attached to it, you can fix it in the following way:

You should specify explicitly which lib files to include (seperated by ;) :
-cp %cd%\lib\lwjdl.jar;%cd%\lib\<another-lib>.jar
Don't be tempted to use the wildcard * as it will cause more harm than good (from previous experience :))

You use the java.library.path option to specify the location of native libraries to load. In the location pointed to by that option you would place all dll or .so files required by LWJGL. On the other hand, you need to make sure that all required JAR files are on your classpath, via the -classpath option. Currently, you have your JAR files in the wrong directory.

In Eclipse, if you using maven.
Add the following to the project "Run" : "VM options" .
-Djava.library.path=yourpath/youproject/java/target/natives

Exporting project with libraries to runnable jar from Eclipse

I was trying to export a test of a game I am working on(that uses the Slick library), to send to my partners who lack any IDE, all went well with the export in eclipse, but when I try to run it from command prompt, this is what I get in return.

Any idea what is going wrong?
NOTE: The project runs perfectly fine in eclipse.

You should read up on a "get started" guide on slick if you are going to use it. Slick has several dependencies who use dll's to communicate with opengl. You need to specify where those dll's are kept so these dependencies can load the dll's. I found this link that might help you do that..

You also need the native lwjgl library and point to it. The Export Jar functionality do not handle this.
Read up on the lwjgl manual for how to do this.

You have to add your jars either to:
the classpath in your java invocation
the Manifest.mf of your main jar
Java won't automatically load your jars until they are in one of these locations.

Try with File -> Properties -> Java Build Path -> Order and Export
