Not finding libraries for JRI - java

I set up a JRI project for NetBeans 7.4 using 32-bit R 3.0.2 and Java jdk1.7.0_45, on Windows 7, using the steps outlined here.
When I called
Rengine.versionCheck()
I got the following
Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.
java.lang.UnsatisfiedLinkError: C:\Program Files\R\R-3.0.2\library\rJava\jri\jri.dll: Can't find dependent libraries

Java Result: 1
Following the suggestions here, I copied all of the dlls from
C:\Program Files\R\R-3.0.2\bin\i386
to the directory containing java.exe. I also right-cliked on the project and selected
Properties:Run:VM Options
and added
-Djava.library.path="C:\Program Files\R\R-3.0.2\library\rJava\jri;C:\Program Files\R\R-3.0.2\library\rJava\jri\i386"
The problem persisted. I tried prepending the following to my code.
System.loadLibrary("jri");
This resulted in
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Program Files\R\R-3.0.2\library\rJava\jri\jri.dll: Can't find dependent libraries

Java Result: 1
I have done everything suggested here but the problem persists.

I had to restart NetBeans. That fixed the problems.
In fact, I found this part unnecessary.
Properties:Run:VM Options
-Djava.library.path="C:\Program Files\R\R-3.0.2\library\rJava\jri;C:\Program Files\R\R-3.0.2\library\rJava\jri\i386"

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.

Crash in Dynamic Code Evolution VM

I verified that SunFontManager is exist in rt.jar. Any idea?
DCEVM does not ship with fonts. So, when the JVM tries to load up the fonts, it doesn't find any and crashes. Fortunately, the fix is very easy. Simply copy the fonts from another JDK/JRE. You will find them at /jre/lib/fonts. Copy the entire directory to /lib.

Exporting java program with processing elements to executable jar

I have a java project with processing elements that compiles and runs fine inside of Eclipse, but I need to export it to an executable. When I do this via Eclipse's export wizard, it produces a jar, but that jar produces runtime errors when it's double clicked or called from the command line. First it was giving me this:

After some googling, it appears this dependency issue might be a bug with jogl: https://java.net/jira/browse/JOGL-346 but I find it hard to believe that nobody has been able to export any processing applications from Eclipse. There's got to be a way, hasn't there?
Any suggestions?
Processing requires native libraries, which it doesn't look like you're including. You need to at least put the JOGL jar for the system you're on, but that won't help you deploy to other systems.
Shameless self-promotion: I wrote a tool that helps you create self-extracting runnable jar files that handle Processing's native libraries automatically so it works on every system: http://StaticVoidGames.com/SvgExe/

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:
Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Users\Francis\AppData\Local\Temp\jniopencv_core7109340164936655704.dll: Can't find dependent libraries

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:

7Zip-JBinding UnsatisfiedLinkError

I've looked through a number of the UnsatisfiedLinkError threads on here and nothing seems to quite fit my problem.
I am trying to get this api working: 7ZipBind
However I am having an issue, and cant get the thing to work. I am running some of its example code from the commandline like so:
C:>java -classpath
"/sevenzipTest.jar;/sevenzipjbinding-AllWindows.jar;\sevenzipjbinding.jar"
com.poc.sevenzip.SevenZipSimple c:\archive\test.zip
However when I try to run it I get the error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\Users\XXXX\AppData\Local\Temp\SevenZipJBinding-9640553\lib7-Zip-JBinding.dll: Can't

What I am confused about, is why it says it cant locate the libraries (dll files), when the libraries are stored within the <file_path>/sevenzipjbinding-AllWindows.jar file... I am obviously not doing something correct here, and was hoping some1 can give me some pointers.
Cheers
The bug fix was released. Please, use version 1.06rc or above.
Download URL:
All versions
4.65-1.06rc-extr-only
The following instructions are for Windows x86 and 7 Zip JBinding version 4.65-1.05 RC. Download the following DLLs.
libstdc++-6.dll
libgcc_s_dw2-1.dll
gpsvc.dll
sysntfy.dll
Add the DLLs into the Windows-x86 directory in sevenzipjbinding-AllPlatforms.jar. Then append the following lines to sevenzipjbinding-lib.properties in the Windows-x86 directory in the jar.
sevenzipjbinding.libname.3=gpsvc.dll
sevenzipjbinding.libname.4=libgcc_s_dw2-1.dll
sevenzipjbinding.libname.5=libstdc++-6.dll
sevenzipjbinding.libname.6=sysntfy.dll
Instead of modifying the jar file, one could put the DLLs in the PATH (not classpath).
In order to figure this out, I extracted lib7-Zip-JBinding.dll from sevenzipjbinding-AllPlatforms.jar. I then opened the file in Dependency Walker.
