I have built a Java 1.8 application under Maven in Eclipse that allows me to generate BIRT reports in a programmatic way without the need for the UI. Within Eclipse everything works fine. If I compile the code into a JAR file and try to run it however I run into problems with java.lang.NoClassDefFoundErrors. Clearly I have a missing dependancy but I don't know how to resolve the problem.
The error is
java -cp target/* com.resonancex.scheduler.Scheduler

I added the library org.eclipse.birt.runtime_4.8.0-20180626-4.8.0 which appears to be the required BIRT runtime. Can anyone give me a few pointers as to what else I may need?
Just in case anyone else tries to do this I thought I would list the libraries I needed to install to get standalone BIRT report generation running running. The list is as follows. Obviously this list may change over time so keep that in mind:

The Tesseract library has a Java wrapper that I've used for months successfully but now seems involved in the error, whatever it is. I've been using the same DLL and started getting this failure, and I've updated the Tesseraact DLL and the wrapper to their latest version.
More puzzling is that the application runs fine within eclipse, and only fails like this when run from a command line (Windows 10). I have uninstalled and reinstalled the DLL a couple of times, rebooted the machine each time, and am running out of things to try. I went through the entire Maven dependencies list and deleted all files found there from my repository, then refreshed the eclipse project to reload all the files in the list.
I saw one suggestion of placing a breakpoint in ZipFile, but that won't help since the problem does not appear in eclipse.
I'm willing to upgrade the Java further, but it would be nice, first, to have some knowledge of what the problem is so that I have some confidence that will fix it.
Can someone suggest what might be wrong, or strategies to find out?
I am trying to use jlink as part of the javafx-maven-plugin plugin to create a runtime image with AdoptOpenJDK 15. For some reason I end up getting the following error during the jlink goal:
Error: java.io.UncheckedIOException: java.nio.file.AccessDeniedException: ...\target\image\bin\javaw.exe
javafx:run, however, works fine.
Note: The path to the project has been omitted from the error message.
Some antiviruses can block the creation of executable files. Check if this is the case and configure your antivirus to exclude ...\target\image\bin\javaw.exe from being checked, or to trust the jlink process to write whatever it wants.
I have extracted a jar from a Maven project that runs the MapReduce job. However, I keep receiving the error "java.lang.ClassNotFoundException". The things that I have tried to use to repair this is:
Configured the classpath
Tried doing job.setJar(.jar)
Attempted job.setJarbyClass(.class)
Changing JobConf path file
Caress Hadoop and tell it everything is going to be okay
I extracted the jar file from Maven and transferred it to a Linux server, and running it from there.
The full error message is:

If there is any missing information needed to answer this question, please let me know, and thank you for reading.
When exporting the jar out of Eclipse, I unchecked "classpath" because I was not running it locally. This fixed my error.
I would like to profile my Spring Web Application that is running on Tomcat and Eclipse. I added VisualVM to the Eclipse and followed below steps to run the application for profiling.
Right click on the application name >
Run As >
Run Configuration >
Java Application >
'Selected Project' >
Set 'org.apache.catalina.starup.Boostrap' as a value for Main class,
also selected VisualVM as the Launcher > clicked on Run button.
The VisualVM starts but shows following message:
"Cannot open requested application"
Under local I can see VisualVM, Eclipse and Tomcat.
Following exception will be thrown and shown on console as well:
Exception in thread "main" java.lang.NoClassDefFoundError:

I reckon the issue is because of wrong server selected. Maybe I should choose Tomcat but not sure how.
Probably an issue with an incomplete classpath when the VisualVM plugin launches Tomcat. You could try to correct the classpath of the start configuration which you created (e.g. try to add bin/tomcat-juli.jar from your tomcat installation) but I doubt this will work easily.
You can try the following:
start your Tomcat, e.g. from Eclipse
then manually start VisualVM: It is actually part of the JDK and located in <JDK dir>/bin/jvisualvm(.exe)
in the application list you should see the Tomcat process and then you can open it with a double click.
Try using Java Mission Control by running jmc. It is included in recent versions of the JDK.
See the getting started doc at http://docs.oracle.com/javacomponents/jmc-5-5/jmc-user-guide/index.html
Run your application, then open the jmc window and connect to the Tomcat process.
This is caused when a class file that your code depends on is not found at run time. This is purely an issue with the class path. Either the class is not exists in the class path or you have a different version of JAR file in the class path. The exception will go away if the class path is corrected.
I'm trying to make a Java program that can communicate with JavaDB. I've made the Database class, started a server and made a tiny client program to check if they would communicate.
The program crashes when i try to run it, giving a class not found exception at the line where i try to set the database driver. I googled it and found that this error appears if derbyclient.jar and derby.jar are not found in the classpath. I also read that the scripts setNetworkClientCP and setNetworkServerCP found in the db directory would set these in the classpath. I found the scripts, ran them, and checked to make sure the classpath got updated, but i still get the same error. Does anyone know what the problem might be?
EDIT: SOLVED - i just realized that i need to include the derbyclient.jar in the NetBeans project library.
I'm using NetBeans and the built in JavaDB. I set the classpath by using the scripts that i mentioned above, and upon checking the classpath i found these entries:
%DERBY_INSTALL%\lib\derbyclient.jar;
%DERBY_INSTALL%\lib\derby.jar;
%DERBY_INSTALL%\lib\derbytools.jar;
%DERBY_INSTALL%\lib\derbynet.jar;
