I'm a bit of an amateur developer and I'm currently messing around with JavaCV and Eclipse on my Mac.
I'm trying to get the FaceRecorgnition to work but I don't really know how to install this into Eclipse properly.
I've created a new Java Project, and I've imported the 'JavaCPP', 'JavaCV-Mac', and 'JavaCV' libraries.
I then created a package and called it 'mvn', then created a class and C/P the 'FaceRecorgnition' java into that class and then try and run it. I then get this error:

I don't fully understand imports and SDKs fully yet, so be easy.
Thanks.
This is not about missing libraries, but a missing .txt file.
It seems like the all10.txt file is not included in the JavaCV download.
Check out http://www.shervinemami.info/faceRecognition.html under the heading
"How to use the offline cmd-based FaceRec system:"
You find the all10.txt file in his zip facerecExample_ORL.zip and the faces needed in the zip
Cambridge_FaceDB.zip
Create a data folder where FaceRecognition.java is.
Put the .txt files in that folder as well as the Cambridge_FaceDB folder:
samples/
FaceRecognition.java
data/
all10.txt
Cambridge_FaceDB/

I am learning to solve some optimisation programs using google or-tools.
I started with their example code and I an trying to run it in intellij.
But when I write the code and compile I get the following error.
Exception in thread "main" java.lang.UnsatisfiedLinkError: com.google.ortools.linearsolver.operations_research_linear_solverJNI.MPSolver_CLP_LINEAR_PROGRAMMING_get()I

I searched for some answers and I found that it requires jniortools.dll .
But I am working with ubuntu. Hence i assume i need to load the libjniortools.so file , am I right?.
So I included the line
static {
System.loadLibrary("libjniortools");
}
and I have a lib folder wherein I have put both com.google.ortools.jar and protobuf.jar along with all the other lib files that were present when I extracted the zip file(basically copy pasted the lib folder from extracted zip file).
I have added the jar paths in intellij as shown in figure
enter image description here
*the last 2 line of dependency in image
Then I have also tried giving the lib path in VM-options:
-Djava.library.path=/home/surajvashistha/IdeaProjects/LPModel/lib
After all this, I get the following error
Exception in thread "main" java.lang.UnsatisfiedLinkError: no libjniortools in java.library.path

I am stuck here and not able to move forward. Can anyone help?
I downloaded the OfBiz Java application and the following line throws an MissingResourceException:
ResourceBundle res = ResourceBundle.getBundle(settingsResourceName);
The value of settingsResourceName is "cache", but I cannot find any file called cache.properties or cache_en.properties.
Where should I be looking? I'm new to Java. All my research on SO says there should be such a file.
I imported OfBiz in Eclipse using the Import menu option and selecting Existing Project from File System (I'm not in front of my dev machine so I don't remember the exact wording). But I chose the root folder of the downloaded OfBiz.
I then added the appropriate VM Arguments in the Run Configuration to get it to run properly at least. And that's it, on the first Run I got the above error. I think it has to do with a missing class path but I don't know what to add to class path.
Here is the stack trace:

UPDATE:
My mistake, I found two files both called cache.properties in the following folders:
ofbiz-trunk/build/resources/main
ofbiz-trunk/framework/base/config
But these are folders, not packages. I tried putting them in the .classpath but that did not work, I still kept getting the same error.
As suspected, I knew it was because of a missing reference to a class path. After looking at a section on this page: http://www.opensourcestrategies.com/ofbiz/ofbiz_eclipse.php, I learned that I was supposed to go to the Java Build Path and in the Libraries tab, click on Add Class Folder, then point that to ofbiz-trunk/framework/base/config. Which is where I have one of the cache.properties files.
I installed Eclipse Neon yesterday and it seemed to be working fine. Installed a few plug-ins and did some work.
Today when I start it I get the following error message:
$ /usr/local/bin/eclipse46
/root/.p2/pool/plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.400.v20160518-1444: cannot open shared object file: Permission denied
I found some references in the config.ini file to the root folder (I have no idea why). I have correct these and the file now looks like:

However, I am still getting the "permission denied" error. Is there any way of correcting this?
I tried to put my user's folder to eclipse.ini file, and this didn't worked.
--launcher.library ~/.p2/pool/plugin /org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.400.v20160518-1444
seems the best approach for now is to copy the folder inside root home to your user, once its create with the the new installer.
I got a very strange error. This what I've done:
I create a project (with Netbeans) which include datanucleuse-core-3.0.0-release.jar. The project can be built successfully. It also ran smoothly when I tried to run it with Netbeans or running 'java -jar <.jar bundle>' in dist folder via command prompt.
The problem is, when I copy that dist folder into another location and tried to run it again with command prompt, it gave these errors:
Exception in thread "main" Error reading manifest file

Anybody got clue ?
I am really sorry for everyone, especially for datanucleus members in StackOverflow.
Apparently the problem is me, not the netbeans, datanucleus API, nor anyone.
As you can see from "jar:file:/E:/!new/BTJ/NCRServer/lib/datanucleus-core-3.0.0-release.jar!/plugin.xml", I put the "dist" folder from Netbeans in "E:/!new" folder. I don't know why but the "!new" folder seems to cause the extra exclamation mark(!) in "release.jar!".
I move the dist folder into D:/ and it worked !!
So, if anyone ever experience this problem (precedence a folder's name with exclamation mark and accidentally put a project with datanucleus-core-3.0.0-release.jar inside it), that's the solution.
Thank you.
we are using PDFlib for personalizing PDFs.
The pdflib.jar library and the libpdf_java.so file are both in the folder:
/home/user/my/custom/library/path/
I start the server with this argument:
java -Djava.library.path=/home/user/my/custom/library/path/
like it is mentioned in the pdflib tutorial
After deploying on my jBoss5 Server i got this error message:
ERROR [STDERR] Cannot load the PDFlib shared library/DLL for Java.
Make sure to properly install the native PDFlib library. For your
information, the current value of java.library.path is:
/home/user/my/custom/library/path/
So, the path ist correct (i tried it with and without the / at the end)
If I put the jar and the lib in my /usr/lib folder, everything works fine, but not with my custom folders.
I use it on a linux 64bit, if that matters!
The custom folder and the files got chmod 755 - so this shouldn't be the problem
Looking forward to your hints!
