I have a javafx program that I was formerly developing in sublime text before migrating to intellij as my editing environment. As of now, I can compile and run without error through the command line (Windows). However, when I try to run it from intellij, I get the following message:

I don't know how to fix this.
The problem turned out to be intellij having an issue with the source folder in the project directory. By moving all my java files to a new directory and reopening it in intellij as a new project with a single, correct source folder, the problem completely went away.
(As stated in the question, the code itself was functional and worked through the command line.)

I have just installed Java1.8.0_112, both jdk and jre 64bit on my Windows 7 machine.
I am attempting to run one of my programs via a .bat file and am getting the following error:
Error: A JNI error has occurred, please check your installation and try again

I have uninstalled and reinstalled the jre and I have restarted my machine. I have made sure I am pointing to all the libraries needed.
What really baffles me is that this error is showing about the POI workbook, but I have all the apache libraries I need and their appropriate dependencies so I'm not sure why this is an issue. Like I said, runs like a charm in Netbeans on the jdk, but completely implodes when I run it on my desktop via .bat
The program runs just fine in the Netbeans8 environment, which is using the jdk of 1.8.0_112 and the JDK8 binary.
My .bat file is as follows, I've added line breaks for readability:

Any help or guidance would be greatly appreciated, thank you!
Found the solution. The .bat file did not like me having libraries on mixed drives. Moving all the libraries to either my C: or the network S: drive solved the issue.
For whatever reason Netbeans was able to handle libraries in multiple locations but the .bat file does not.
I'm developing a Java Swing application using some features of JavaFX 2(such as WebBrowser).
I tried to reference the jfxrt.jar file from inside my folders, since it seems that a javaFX2 installer for MAC is not available (only installing Java 7).
But I would like to use JavaFX 2 also with Java 6.
I get this error:

JavaFX 2 does not support Java6 on OS-X - Java6 is only supported on win32
I have made a application to grab video from a webcam and detect motion using OpenCV and JavaCV. I am trying to export as an executable jar using eclipse. The program runs fine in eclipse as does the exe jar on the computer I coded the program on.
What I am trying to accomplish is to make the exe Jar run on computers that don't have OpenCV installed. Basically what I would consider a portable application. When I run the exe jar on a different computer that has nothing installed other than the JRE I get unsatisfied link errors seen below.

I have looked for a solution to what I am doing wrong. Most of the topics I have come across with unsatisfied link errors like the ones I am receiving have been trying to get it to run the first time through within there IDE, which is not the case here. I would think my dependencies are correct in the libraries in the build path since I can get it to run perfectly when I am on the computer that has everything installed but I still believe I am doing something wrong with the build.
Again I am trying to make it so the Jar can run on computers where OpenCV/JavaCV is not installed. Any help would be greatly appreciated.
If opencv is not installed in the target machine, than you need to deliver the necessary opencv's dll file and set the corresponding library path, opencv is a precondition of javacv
for example:
jar yourapp.jar -Djava.library.path="/path/to/OpenCV/library"

Well, I exported my application into JAR with eclipse, but now whenever I try running it I get the: "A Java Exception has occurred". When I try to run it through command line it says:

Any solutions to this? I just hate java for this... It never works on desktops when you want it to... sorry I'm really stressed out from this, I'm overreacting...
Any ideas what could cause this? I doesn't work on other computers as well. Right now it's using Java 1.7. And the application runs perfectly on Eclipse.
You need to get your dependencies. Looks like you are depending on swt, which is not part of the core java language. You'll need to get all the third party jars that you depend on and include them in your classpath. It runs perfectly on eclipse because eclipse takes care of setting up the classpath for you.
You can set the classpath in your manifest file as described in the documentation, or you could include a script to start your application that will use the -cp command when running the jar, or you can use something that will package everything into one monster jar like the solutions to this question.
I have a webservice client created using cxf. When I run from eclipse I dont get any errors. But when I create a jar out of the files and run it from cmd prompt , I get NoclassDef exception or ClassNot found exception. I have set the classpath, java home correct.
1. Exception
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
2. Exception
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/cxf/databinding/DataBinding

The web service is in C# wcf and the client was created without JAXBinding element.
Anyhelp will be appreciated.
Thanks,

This is a typically and easiy-to-solve classpath problem: The cxf library (-ies) is/are missing on the classpath. Start the application like this:
java -cp <youJar.jar>;<cxf.jar>[;<another-cxf.jar>;...] my.pkg.Application
You'll have to replace the name of the main class and the values of the -cp parameter with the paths and names of your jar and all other libraries that are required to run the application.
Why does it work from eclipse: In eclipse, you've set the build path correctly, but this builds path is not exported or added to the jar.
