I have a problem running the below java code outside of the eclipse compiler. Inside the compiler it works fine, but after exporting as a runnable jar I get an InvocationTargetException. I believe it is relevant to the dll files but after reading other solutions here and tryinging to implement them the problem remained unresolved. So my question is it possible to configure eclipse, through code or settings, to export the program correctly?
Relevant Code

In case anyone has a similar issue what I did was copy the 3 .dll files into my System32 folder. I then got an issue with image.io, which the site had plenty of answers for. My personal solution was exporting the jar as my code and a separate folder for the libraries.

I want to export my Java project to a standalone Jar or exe file. I use blueJ as an IDE and I use following libraries: GLOOP, JOGL and GlueGen (aswell as pi4j). Running the program in the IDE itself works flawlessly, however when I export the program as a .jar file and wrap it into an exe with Launch4j I get following error:

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:

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

net.java.games.input.DirectAndRawInputEnvironmentPlugin is not supported
Process finished with exit code 1
I know this thread is old, but for people who are searching for the solution.
The answer is, you have to include the native libs to your project. For the use of jinput.jar you have to include following libs:
jinput-dx8.dll
jinput-dx8_64.dll
jinput-raw.dll
jinput-raw_64.dll
You can download the natives here DOWNLOAD.
You will get a jar-file. Unzip the file with winrar to get the dll-files.
Now go to project and open the context menu with a click on the right mouse button -> Build Path -> Configure Build Path -> Choose the Libraries tab -> Click on the little arrow next to the jinput.jar to expand the view -> Make a double click with the left mouse button on Native library location -> Choose the directory of the dll-files.
Confirm the dialogs and try to run your program again.
In LWJGL there is a "native/" folder containing the respective native libraries for each platform/OS. Just choose your platform and set java.library.path to that directory.
This is your problem.
First Step:
Create a folder and rename it to LWGJL_New then in that folder create two other folders and rename the first on libs and the second one natives.
Now go to the LWGJL library that you have downloaded. Copy the jar files to LWGJL_New/libs. Then go to the LWGJL library that you have downloaded, in it, there is a folder containing respective native libraries for each platform/OS.
Choose one of them that you need and copy it to LWGJL_New/natives.
Second step:
Go to the module settings of your project(F4) then click library.Click add sign(+).Click on java. Now find the LWGJL_New folder and in it click on the jar folder and click ok. Then Click on Apply and ok.
Third step:
Now if you run your project you will occur that problem, So go to the Edit Configuration part
Then in VM options write this:
-Djava.library.path="***"
Instead of star signs write the address of the native folder that we have just created.
For example ->
D:\LWGJL_New\natives\windwos
D:\LWGJL_New\natives\linux
Then click on OK.
Then run your project.

Is there a different way to declare windows path, which works in both, eclipse and cmd?
update (the findStreamInClasspathOrFileSystem method):
private static InputStream [More ...] findStreamInClasspathOrFileSystem(String name) throws FileNotFoundException
{
String path = null;
if (name.startsWith("/")) {
path = name.substring(1);
}
// - even though this may look like a regular file, it may be a path inside a jar in the CLASSPATH
// - check for this first. This takes precedence over the file system.
InputStream is = null;
if (path != null) {
is = IOUtils.class.getClassLoader().getResourceAsStream(path);
// windows File.separator is \, but getting resources only works with /
if (is == null) {
is = IOUtils.class.getClassLoader().getResourceAsStream(path.replaceAll("\\\\", "/"));
}
}
// if not found in the CLASSPATH, load from the file system
if (is == null) is = new FileInputStream(name);
return is;
}
update: no matter if i change the path to:
"c:/DP/lemma/models/english-left3words-distsim.tagger");
"c:\\\\DP\\\\lemma\\\\models\\\\english-left3words-distsim.tagger");
its behaviour is still the same (works in eclipce, not in cmd)
Your code seems to load a resource from the classath, using the ClassLoader. The path should take the following form:
com/yourcompany/yourapp/english-left3words-distsim.tagger
where com.yourcompany.yourapp is the package where the file resides.
See http://docs.oracle.com/javase/6/docs/api/java/lang/ClassLoader.html#getResource%28java.lang.String%29
EDIT:
The code of IOUtils.getInputStreamFromURLOrClasspathOrFileSystem() passes two badly formatted paths (c:\... and c:/...) to ClassLoader.getResourceAsStream(), and expects this method to simply return null instead of throwing an exception, which is wrong. I would simply decide where I want to load the resource rom: either the classpath (and thus use ClassLosader.getResourceAsStream()) or the file system (and thus use new FileInputStream()).
I modified a Java code in Eclipse on my laptop with a Windows O.S. Now I have to run the code on a linux O.S. via SSH. I copied all the files and I tried to compile the code. The compilation went well, so there were no errors in the code. Anyway, when I tried to run it, the following errors appeared on the shell:

Do you know what kind of the problem is?I'm new in Java coding, so I don't know how to solve it. Thank you.
wrong name: models/TanaModel
This means it expected to find TanaModel.class under the models directory, but found it somewhere else (maybe the current directory?). Put the class file in a the models directory, and run it as
java models.TanaModel
Java expects class files to be organized in directories that mirror the package structure you used in your source code.
java.lang.NoClassDefFoundError: TanaModel (wrong name: models/TanaModel) at
What command did you run, I'm guessing java TanaModel ?
Most likely your TanaModel is declared to be in package models;
Try calling it like this:
java models.TanaModel
If it is a Eclipse security issue, this would help.
//Java Code

AccessController.doPrivileged(new PrivilegedAction<Object>()
