I have two files, in the same package. I've only shown this one because I do not believe the other file is the problem.
I followed a tutorial on how to use java libraries: download, import, build path etc.
The problem here is, the import seems to be fine but actually using the library is the problem.
I'm very new to Java so sorry if this is a very simple error to fix.
Thank you for any response/feedback in advance.

The referenced library you are using (apache common lang3) and any other library for that matter is used in three different ways.
First, you need the library during development, so your IDE can
validate your code, when you call classes, objects and methods from
the library.
During compilation you need the library, so the java
compiler can reference the right paths, and optimize your code,
where possible.
You need the library during runtime, when your program is run by the Java Virtual Machine, so it can find whatever you used from the library.
The first 2 are usually seen as one, because both is usually considered 'compile time', though strictly speaking only the second one actually is. This means that you need to have the library in place for the IDE (for points 1 and 2) and for the program (point 3). Your exception is thrown, because during runtime, your library is not found by the ClassLoader. The ClassLoader is the way the JVM loads classes for the programs it uses. If the JVM does not find a class, it cannot continue to execute the Thread you are running, and you are probably only running one Thread (a main thread).
Therefore your program breaks, and stops running. Please either recheck the tutorial you are using on how to correctly import libraries or export the library to the lib folder next to the jar you are exporting.
Edit: When using an up to date version of eclipse, and exporting a project as runnable jar, you are asked what way you want to handle libraries:
If you do not see this subsection of the export dialog, you are doing something wrong (probably you are not exporting as runnable jar).

Could not load JIntellitype.dll from local file system or from inside JAR

I am trying to use JIntellitype to listen to global hotkeys but I get this error:

I have loaded the jar file and I also pointed to the folder where the dlls are located through Referenced Libraries.
Here is the code I am trying to run:
import com.melloware.jintellitype.HotkeyListener;
import com.melloware.jintellitype.IntellitypeListener;
import com.melloware.jintellitype.JIntellitype;
public class HotKey extends Thread implements HotkeyListener, IntellitypeListener {
private final int CTRL_C_SHIFT = 10;
public HotKey()
{
JIntellitype.getInstance().unregisterHotKey(CTRL_C_SHIFT);
JIntellitype.getInstance().registerHotKey(CTRL_C_SHIFT, JIntellitype.MOD_CONTROL + (int)'C', JIntellitype.MOD_SHIFT);
if (!JIntellitype.isJIntellitypeSupported())
{
System.exit(1);
}
}
#Override
public void onIntellitype(int arg0)
{
}
#Override
public void onHotKey(int key)
{
if (key == CTRL_C_SHIFT)
{
System.out.println("smg");
}
}
}
Any idea how to fix this?

Your problem will occur because of a version problem between that OS version and the JRE version.
You should check:
Whether an appropriate dll file is installed in your OS system folder.
JIntellitype package has two dll files, one is for 32bit OSs and the other is for 64bit OSs, they have different names.
Check your Java Platform version in the properties of the projects.
You can try to change the Java Platform, if there are more than one types of JDKs.
Make sure about which one is for 64bit or 32bit version.
Have good luck!

I recommend you do something like this:
try
{
JIntellitype.getInstance().unregisterHotKey(CTRL_C_SHIFT);
MyHotKeyListener hotKeyListener = new MyHotKeyListener();
hotKeyListener.addObserver(new MyEventListener());
JIntellitype.getInstance().addHotKeyListener(hotKeyListener);
JIntellitype.getInstance().registerHotKey(CTRL_C_SHIFT, JIntellitype.MOD_CONTROL + (int)'C', JIntellitype.MOD_SHIFT);
}
catch (JIntellitypeException je)
{
logger.warn("JIntellitype initialization failed.");
// DO WHATEVER (NOTIFY USERS?)
}
I can point to other threads, including one where the creator of this library himself denies problems with the library. However, many users such as myself encounter these sort of problems from time to time where JIntellitype fails to initialize and the only solution is to reboot the computer. Because of this, you should catch the JIntellitype exception (the only exception thrown by the library) and warn users (via dialog window) that the hotkey failed to register. You should give them the option to continue without them, or to reboot the computer and trying again.
Trust me.... unless this is a constant problem (which means you configured it incorrectly), it is your best alternative. This WILL happen from time to time at random.

Unable to load library 'libtesseract302':Module cannot be found (Windows10)

We are trying to make software for a car parking system using image processing. We used OCR. We intend to use a webcam to obtain images of the license plate when the vehicle leaves and enters. We will then use the number to calculate the time spent inside the park and price tickets based on that.
This is my code:
import java.io.File;
import net.sourceforge.tess4j.ITesseract;
import net.sourceforge.tess4j.Tesseract1;
import net.sourceforge.tess4j.TesseractException;
public class TestOCR {
public static void main(String[] args) {
File imageFile = new File("C:"+File.separator+"projects"+File.separator+"plate.tif");
//ITesseract instance = new Tesseract(); // JNA Interface Mapping
ITesseract instance = new Tesseract1(); // JNA Direct Mapping
try {
//String result = instance.doOCR(imageFile);
//stem.out.println(result);
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}
When I run this, I get this error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'libtesseract302': The specified module could not be found.

Initially we had a NoSuchFieldError and after using Maven to fix that we encountered this problem.

Basically this error would come either of below reasons
dll path are not specified properly. You can add in vm argument as below. -Djna.library.path=<folder_contains_dll>, This folder should have three dll files gsdll64.dll,liblept168.dll and libtesseract302.dll
You should have Visual C++ Redistributable for VS2012 installed. Windows 10 doesn't have this installed by default.
You may do below steps to start with
Install Visual C++ Redistributable for VS2012 if its not installed
Clone the project from https://github.com/mnadeem/ocr-tess4j-example
Import the maven project in eclipse
Run the Java class TesseractExample.java

Why do I get "LoadLibrary failed with error 1114: a dynamic link library (DLL) initialization routine failed"?

When I run my java application program an error window appears saying that
"LoadLibrary failed with error 1114: a dynamic link library (DLL) >initialization routine failed".
I have tested my code on a different machine and it worked perfectly.The program shows a PApplet window with a map inside.However, Running the code on my laptop, the PApplet appears and all of the sudden the DLL error stops the rest from being shown.
What the problem could be and how can I fix it?
Here is the code I am trying to run. It is worth to mention that it runs successfully if I remove what's inside the setup() method.
import de.fhpotsdam.unfolding.UnfoldingMap;
import de.fhpotsdam.unfolding.providers.Google;
import de.fhpotsdam.unfolding.utils.MapUtils;
import processing.core.PApplet;
public class LifeExpectancy2 extends PApplet {
UnfoldingMap map;
public void setup()
{
size(800,600,OPENGL);
map = new UnfoldingMap (this, 50, 50, 700, 500, new Google.GoogleMapProvider());
MapUtils.createDefaultEventDispatcher (this, map);
}
public void draw()
{
}
}

I had the same issue after I installed my Netbeans to build some projects in PHP and it was fixed changing some graphics options in the control painel of my Windows 10.
Take a look on this video and see if it fixs your issue as well:
Windows 10 - Java Loadlibrary Error 1114
I hope it can be helpful!

Which Unfolding version did you download? You seem to use some Java IDE (and not Processing's one) so you need the Unfolding-for-Eclipse distribution which includes all needed native libraries (i.e. also the DLL in question).
For the records, the DLL is the native library for Windows OS to bind Java to the OpenGL API (JOGL).

java.lang.UnsatisfiedLinkError: jssc.SerialNativeInterface.getSerialPortNames()

I'm doing a processing based project with eclipse and Procliping. When I'm testing the project with "Run" command inside the IDE, everything works fine. But if I export it into a runable-jar, when I run the jar it'll give this error on the line String[] li=Serial.list();. Any idea what's going wrong?
Java source attachment is "processing-2.2.1/modes/java/libraries/serial/src"
And here is a sample code:
package abcd;
import processing.core.PApplet;
import processing.serial.Serial;
public class TestUI extends PApplet {
Serial port;
public void setup(){
System.out.println(Serial.list());
}
public void draw(){
}
public static void main(String _args[]) {
PApplet.main(new String[] { abcd.TestUI.class.getName() });
}
}

My approach of solving it:
Download the latest version of java-simple-serial-connector(Which is the base library used for Processing's serial library), replace jssc.jar in the lib folder, and the error will be gone, and my application runs smoothly.
However the base library is 4 times bigger than the modified version used in Processing, so there may be some unnecessary features involved.
Seems like in their latest alpha version, Processing solved the same problem for exporting apps(at least in windows) by adding more look-up paths, while keeping their Serial library intact. I'm not familiar with their development environment, so I didn't look further into it. There may be a simpler solution.
