I'm doing a college project using Java and Eclipse. The app works perfectly in Eclipse, but when I export it as Runnable Java File it doesn't work. No any error is shown, and nothing is opened.
Do you have any tutorial about how to export it correctly? The application is too long to post here. However, if you need to see any part of code just ask.
EDIT : Error returned by console

Here is one good article on jar creation and execution http://javarevisited.blogspot.in/2012/03/how-to-create-and-execute-jar-file-in.html
I've solved the problem! I don't know why, but It was caused by BufferedInputStream so I changed it by InputStream and the application works perfectly, thanks everybody!

However, it works when I run it inside of the Eclipse IDE. Any ideas? I'm not sure if I'm somehow missing a proper jar file even though java.utils.regex should come included in rt.jar. Is there a way to check if this is missing somehow when I package the jar?
So, this is your problem. java.util.regex.Matcher.results is in Java since Java 9 and you are running the .jar with Java 8.
Eclipse runs with Java11.
Install as default JRE at least Java9 in your OS (Windows ?).
i have been using eclipse, mars, neon and oxygen and i always had the same problem after some days/weeks of using its.
When i press run. It sometimes likes not to work and with no reason scream
Error: Could not find or load main class test.PingSwitchPing
and sometimes after i press run a few more times it suddenly works...
other times when i make some changes to code eclipse doesn't compile to make changes and run old code...
this time it is giving me something that it can't even replicate right now so i cant show error message, but basically the error was about not seeing class path to external libraries and to other parts of code that where in diffrent folder. While it was in phase on loading javafx application.
Why is it so unstable ? it is really piss me off becouse sometimes i am loosing hours to fight with it...
Sometimes i remove .m2 folder and redonwload everyting and it is helping. Cleaning project do nothing to this.
Sometimes restarting pc and eclipse works other times it dosen't...
I was just writing that i can't replicate main error but when i changed on line of code and run then it occurs. When i change it back nothing change. it still dosent work and dont want to work...

I'm building a desktop application with an Apache Derby database. When I run the application from Netbeans, it works fine, but when I run the application's executable jar file, I get a "java.lang.ExceptionInInitializerError" "Caused by: java.lang.IllegalStateException: Attempting to execute an operation on a closed EntityManager."
The jar file was created by right-clicking the project in Netbeans, and clicking "Clean and Build".
I've looked at the the following resources, but the information wasn't applicable:
Export JAR with Netbeans
https://netbeans.org/kb/articles/javase-deploy.html
This is my first time using Derby, so it's probably something simple that I'm missing.

As it turns out, I made a (very) silly mistake in my code. I closed the EntityManager that I made the query on in the line before I called getSingleResult() on my query. I'm not quite sure why the program worked when I ran it from Netbeans, but the problem is solved now.
After creating a number of Android apps using Java in Eclipse. I now need to create a stand alone Java program so that I can create an sqlite database - that will eventually be used in a future Android app.
I am using the SQLJet library from http://sqljet.com and have copied their example code.
When I try to run the code by using the "Run" button in Eclipse I get the following error.

Now as the code has been copied without change, I am guessing there is nothing wrong with that and I suspect that I don't have my environment set up correctly. As a newbie Java developer (normally C#) I'm struggling to make sense of what the problem is. never mind the solution.
Code now working and the database is created. Unfortunately looks like it is not compatible with the sqlite3, the version Android uses. Back to the drawing board...!
The program needs the class org.antlr.runtime.RecognitionException. See here for a list of jars where you can find it: http://www.jarfinder.com/index.php/java/info/org.antlr.runtime.RecognitionException

I get this error when I run from the command line, however, it does not cause any issues with my program running on my machine, however, on other peoples machines the program will not run at all.
I have never come across this error before and fairly confused.. mostly that it runs fine on my machine, but not on others even though it throws this error on both.
This is a classpath error. Its likely that you have it set up right for compile time but not runtime. Make sure that either your jar is in the right location and/or that you've set your classpath to include the jar.
Go to the Jintellitype website, download the source, add it to your download folder and then move the .dll files into the folder with the Jitellitype classes after building the project
