Java - ClassNotFoundException: java.net.http.HttpClient

I'm attempting to run a jar file on a windows VM. When testing it using the CMD prompt, I get this error -

I think the class it's saying it can't find is httpclient-4.0.1.jar which is on the 6th line if the MANIFEST file. The only issue I can think of is the Class-Path at the end of the MANIFEST being just .
I also unzipped the .jar file, to make sure the relevant .jar files are actually present, which it is (assuming httpclient-4.0.1.jar is the correct file).
I can run other .jar files on this VM, though none with this class in it. I've updated Java as well, just in case, which didn't help.

httpclient-4.0.1.jar most probably means version v4.0.1 of org.apache.httpcomponents:httpclient.
And java.net.http.HttpClient was intriduced since 11 version of JDK.
Didn't you forget to use correct version of jre/jvm?

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 exporting Jar using Weka

i've got a big problem exporting my project as a jar file (inside my project i use weka). I'm using Eclipse.
I've added in Java Build Path weka.jar and i've attached to it weka-src.jar, testing my classifier under eclipse everything works, so i've decided to create a jar (because i need that another program use it).
First of all i've created the manifest file:
Manifest-Version: 1.0
Rsrc-Class-Path: ./ weka.jar weka-src.jar
Class-Path: .
Rsrc-Main-Class: start.Home
Main-Class: start.Home
The main class of the program is Home (inside the package start), while weka.jar and weka-src.jar are inside the /src/ directory of the eclipse program.
When i try to execute the jar created i receive this output:
Error: A JNI error has occurred, please check your installation and try again

I think that the problem is the CLASSPATH so i've tried to solve it in this way:
I've created the Environment Variable CLASSPATH with this values:
C:\Users\tomma\Desktop\workspace Eclipse\AndroidPermissionsClassifier\src\weka.jar
C:\Users\tomma\Desktop\workspace Eclipse\AndroidPermissionsClassifier\src\weka-src.jar
but nothing changed, can someone help me please?

You are right: the classpath is the problem. Did you remove the items from the manifest classpath when you added them to the environment CLASSPATH? (Side note: place the source jar in the -sourcepath, not the classpath.)

Java - Library path error

I'm trying to start my java game but I have some troubles with the java command line:

C:\>java -Djava.library.path=%cd%\lib -jar game.jar

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
