Missing class from package within Netbeans when using Spire.Doc.jar for docx files

I downloaded and installed the free Spire.Doc.jar file to work with .docx files. When I run it within Netbeans the functionality works fine however when I attempt to build the program I am getting the following error:
warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '1.8'
Note: Creating static metadata factory ...
error: com.sun.tools.javac.code.Symbol$CompletionFailure: class file for com.spire.doc.packages.spryOb$1
not found
An annotation processor threw an uncaught exception.
Consult the following stack trace for details.
java.lang.RuntimeException: com.sun.tools.javac.code.Symbol$CompletionFailure: class file for com.spire.doc.packages.spryOb$1 not found
I have added the .jar file to my class path however there appears to be a class file missing from the com.spire.packages location.
Does anyone know if this is a Netbeans issue or does it look like there is an issue with the .jar file? I find it strange that it works when I run it within Netbeans but the above error occurs when I attempt to build the project.

I managed to get my application to build. What I had to do was remove the following code from my class and then it worked:
document.getMailMerge().MergeImageField = new MergeImageFieldEventHandler()
{
#Override
public void invoke(Object sender, MergeImageFieldEventArgs args)
{
mailMerge_MergeImageField(sender, args);
}
};
private static void mailMerge_MergeImageField(Object sender, MergeImageFieldEventArgs field)
{
String filePath = field.getImageFileName();
if (filePath != null && !"".equals(filePath))
{
try
{
field.setImage(filePath);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
I'm not sure why it didn't work with this included however I got this code from the following website:
https://www.c-sharpcorner.com/article/how-to-perform-mail-merge-in-word-document-in-java/
therefore I will inform them in case this happens to someone else in the future.

Java: I do not Understand the Relative Paths

I've got following maven project structure as also seen in here (ProjectStructure) :
-maws20.algorithm
|-src/main/resources
|-images
|-menuBanner
|-linearSearchMenuBannerUnsorted.png
|-src/main/java
|-linearSearch.menu
|-LinearSearchMenuBanner.java
I am trying to load that .png image inside of the LinearSearchMenuBanner.java-File with the following Line:
#Override
public Image loadBackgroundImage() {
return new Image(LinearSearchMenuBanner.class.
getResource("/images/menuBanner/linearSearchMenuBannerUnsorted.png").toString());
}
Is this not the correct relative path? Because I get the following error:
...
Caused by: java.lang.NullPointerException: Cannot invoke "java.net.URL.toString()" because the return value of "java.lang.Class.getResource(String)" is null
at linearSearch.menu.LinearSearchMenuBanner.loadBackgroundImage(LinearSearchMenuBanner.java:20)
...
(Line 20 is the line shown above)
I thought I understood the relative paths in Java. ^^'
Thank you for any help.

Remove the first back slash /, which actually means absolute path not the relative path.
Try this:
#Override
public Image loadBackgroundImage() {
File resource = new ClassPathResource("images/menuBanner/linearSearchMenuBannerUnsorted.png").getFile();
return new Image(new String(Files.readAllBytes(resource.toPath()));
}

Thanks for all your help. I don't know what went wrong, but when i create a completly new Workspace after that create all files new and copy the source code to the new files. Then it works fine.
I dont know why...
But thank you very much :)

I guess this is related to your packaging. The image needs to be on the servers file system, the JAR resources will not work!
ClassPathResource
Supports resolution as java.io.File if the class path resource resides in the file system, but not for resources in a JAR. Always supports resolution as URL.
You are in package search.menu and you need to access the file resource in images/menuBanner So you need to load a resource:

new ClassPathResource(“../../images/menuBanner/linearSearchMenuBannerUnsorted.png
“, LinearSearchMenuBanner
.class).getFile();



Hava a look into other options here:

OCR Logger Could Not be Resolved-Java

So I am trying to get an OCR working for a bigger project that reads characters from an image and I am following this you tube video: https://www.youtube.com/watch?v=aEMSxiXctPk
I did everything in the video and still cannot get it to work. I looked on this forum about the error I am getting, but it looks like their projects are different so I think they need different jars than I would. I have all of the jars from the video or at least I think I do. Any ways, the issue in java delivered this message.
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
The type org.slf4j.Logger cannot be resolved. It is indirectly referenced from required .class files
org.slf4j.Logger cannot be resolved to a type
LoggerFactory cannot be resolved
The method setDatapath(String) of type Tesseract must override a superclass method
This is my code:
package Tess4j;
import java.io.*;
import net.sourceforge.tess4j.*;
import org.slf4j.*;
public class test {
public static void main(String[] args) throws IOException{
File imageFile = new File("C:\\Users\\Sean\\workspace\\Bigno Tracker\\Images\\eurotext.png");
ITesseract instance=new Tesseract();
instance.setDatapath("C:\\Users\\Sean\\workspace\\Bigno Tracker\\tessdata");
try {
String result=instance.doOCR(imageFile);
System.out.println(result);
}catch (TesseractException e) {
System.err.println(e.getMessage());
}
}
}
This is an image of my screen that shows the jars I have.
So what am I missing?
Thanks in advance.
Edit:

I don’t really understand your question but, I’ve done some work with OCR Engines in the past.. ABBYY hass a good one that’s really easy to integrate!
P.S Did a little research, check to see if you have all the appropriate dependencies for your OCR engine version
Cheers

Running XSLT to RDF framework fails because of Saxon

I´m using Krextor to convert XML to RDF. It runs fine from the command line.
I try to run it from Java (Eclipse) using this code.
private static void XMLToRDF() throws KrextorException, ValidityException, ParsingException, IOException, XSLException{
Element root = new Element("person");
Attribute friend = new Attribute("friends", "http://van-houten.name/milhouse");
root.addAttribute(friend);
Element name = new Element("name");
name.appendChild("Bart Simpson");
root.appendChild(name);
nu.xom.Document inputDocument = new nu.xom.Document(root);
System.out.println(inputDocument.toXML());
Element root1 = inputDocument.getRootElement();
System.out.println(root1);
Krextor k = new Krextor();
nu.xom.Document outputDocument = k.extract("socialnetwork","turtle",inputDocument);
System.out.println(outputDocument.toString());
}
I have the following problem problem
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/saxon/CollectionURIResolver
Caused by: java.lang.ClassNotFoundException: net.sf.saxon.CollectionURIResolver
I have included Saxon9he in the classpath, and I have also added manually as a library in the project but the error is the same.

I am the main developer of Krextor. And, #Michael Kay, actually a colleague of Grangel, so I will resolve the concrete problem with him locally.
So indeed the last Saxon version with which I did serious testing was 9.1; after that I haven't used Krextor integrated into Java but mainly used Krextor from the command line.
#Grangel, could you please file an issue for Krextor, and then we can work on fixing it together.
Indeed, #Michael Kay, for a while I had been including more recent Saxon versions with Krextor and updated the command line wrapper to use them (such as to add different JARs to the classpath), but I have not necessarily updated the Java wrapper code.

Problems using Matlab Builder JA

First of all I would like to thank in advance everyone for reading such a long post. I really appreciate your help.
The thing is that I've been doing some research on how to "connect" Matlab and Java for a project I am working on for university. I figured that the most suitable option was using Matlab Builder JA, but I'm having a lot of troubles with it.
I follow step by step the instructions described on a tutorial (the link of the video in below) but get compilation errors over and over, and I really don't know how to fix them. The tutorial is about creating a Java package (demo.jar) with MATLAB ("com.demo"), which contains a class (MLTestClass) with a function makeSqr(n) which returns an n × n square matrix. Then I go to Eclipse, I add to the project both libraries javabuilder.jar and demo.jar and then create the following class:
public class Driver {
public static void main (String[] args) {
MLTestClass x = null;
Object result [] = null;
try {
x = new MLTestClass ();
result = x.makeSqr (1, 5);
System.out.println (result [0]);
} catch (MWException e) {
e.printStackTrace();
}
}
}
Of course I import com.demo.* and com.mathworks.toolbox.javabuilder.*.
Here are the errors the console gives me:
Exception in thread "main" java.lang.ExceptionInInitializerError

... 10 more
Just in case, link tutorial (it's the video): http://www.mathworks.nl/products/javabuilder/description2.html
Anyone has any ideas what the problem could be? It says something about NullPointerException, but I don't know how to solve it as the constructor is provided by the class created with MATLAB. I didn't have any issues installing MCR, and by the way I have MacOS, which I hope is not the source of the problem :).
Again, sorry for the long post and thank you for your time.
Béntor.

Yes, please install MCR. The installation also mentions about setting environmental variables like LD_LIBRARY_PATH etc. If you are using eclipse, i would recommend you update the environmental variables
right click->
properties ->
run/debug settings->
environmental variables
I also had to make sure that variable MCR_CACHE_ROOT pointed to different directory since my home directory was not big enough.

You have install MCR (avaliable in http://www.mathworks.com/products/compiler/mcr/index.html)

None of the above solutions helped me (I already had MCR installed and Macs use DYLD_LIBRARY_PATH instead of LD_LIBRARY_PATH), and noone else online seemed to know. Finally in desperation, I tried editing the DYLD_LIBRARY_PATH and finally got it to work by removing the last part of it: /Applications/MATLAB/MATLAB_Compiler_Runtime/v82/sys/java/jre/maci64/jre/lib
Now the demo application from the tutorial works.
Next comes trying to make my code work.
