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

I have a Java program that reads and processes HDF5 files. I got the below error when I ran it on Eclipse (windows OS), and had to add a run configuration VM argument (-Dncsa.hdf.hdf5lib.H5.hdf5lib=\jhdf5.dll) to add the library and run properly. Now I'm exporting a runnable Jar file I get the error again, likely because it doesn't inherit the VM argument.

Based on this post, I see that two possible options are to create a shell script or application bundle to incorporate the VM argument.
However, I'm curious is there is a more simple way to identify the library for the runnable JAR file. Any suggestions?
Not sure if you have specific needs, but maybe check out jhdf.io it's a pure Java HDF5 library so doesn't require native libraries to be loaded. It should be simple to add to a Maven or Gradle project with standard dependencies.
It's quite an early stage but should support reading data from most HDF5 file, if it doesn't work open an issue.
Disclaimer: I am the author of jhdf so might be biased.
Hello so I'm new with libraries and i followed a Youtube tutorial
https://www.youtube.com/watch?v=HRaJXVuZjRM
and he imports the libraries there and it works, i did too as he did and it works (when in eclipse), however the problem comes later, when i export the app (i always click package but have tried extract and doesn't work either), i cannot open the .jar file.
I have seen already countless threads with this problem, i searched on google and found this:
http://wiki.lwjgl.org/index.php?title=Setting_Up_LWJGL_with_Eclipse
which is basically what he did in the video, i open my manifest file inside of the jar file with 7zip and i get this:
``
Manifest-Version: 1.0
Rsrc-Class-Path: ./ jinput.jar jogg-0.0.7.jar jorbis-0.0.15.jar lwjgl.
jar slick.jar
Class-Path: .
Rsrc-Main-Class: com.tutorial.main.Game
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader"
And if i run the application with the console i get this error:

I suppose it means that it cannot find the libraries and stuff but i have already tried creating a lib folder and a natives folder inside, placing the stuff there and changing the manifest into this:
"
Manifest-Version: 1.0
Class-Path: lib/jinput.jar lib/jogg-0.0.7.jar lib/jorbis-0.0.15.jar
lib/lwjgl.jar lib/slick.jar
Main-Class: com.tutorial.main.Game
"
But it doesn't run it either, i really don't know what I'm doing wrong...
I found a temporal fix for anyone with this problem, remove the natives from eclipse (the native link) and then export and use JarSplice to generate the .jar, if you are using music and cannot open it just open the .jar create the folder you used for your files in your workplace (mine was res) and then drag the music files in there instead of outside... this is temporal since I'm sure there's better ways to do it.
I made a game that uses external libraries and resource files. Now I want test it on another PC(with Ubuntu OS), I tried to run it without eclipse by exporting to jar files, but it doesn't work. This is the hierarchy. Is there any simple way to do this ?
Edit
When I export it as Runnable(Note that I'm trying to run it still on windows not ubuntu) jar file and try to run it java -jar gra.jar It throws:

Make sure you are getting your resource files correctly, not referencing them in your local file system.
To ensure your resources are put in the JAR add them to your classpath.
Caused by: java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path
lwjgl is not found. It should be in one of the directories listed in java.library.path.
You most certainly added a directory to java.library.path with the native dlls of jwgl when you set up your project. Eclipse cannot export this. You will have to create a starter script (sh, bat) which adds the dlls.
Have a look at the last step here:
http://www.lwjgl.org/wiki/index.php?title=Setting_Up_LWJGL_with_Eclipse
How did you pack the jar? If you used solely eclipse, you should use jarsplice. That may fix the error

I get this error when I run from the command line, however, it does not cause any issues with my program running on my machine, however, on other peoples machines the program will not run at all.
I have never come across this error before and fairly confused.. mostly that it runs fine on my machine, but not on others even though it throws this error on both.
This is a classpath error. Its likely that you have it set up right for compile time but not runtime. Make sure that either your jar is in the right location and/or that you've set your classpath to include the jar.
Go to the Jintellitype website, download the source, add it to your download folder and then move the .dll files into the folder with the Jitellitype classes after building the project

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
