    Are you sure about the com. prefix in your class name:

    java -cp OmniIDE.jar;lib\AbsoluteLayout.jar;lib\appframework-1.0.3.jar;lib\beansbinding-1.2.1.jar;lib\swing-layout-1.0.4.jar;lib\swing-worker-1.1.jar com.omniide.OmniIDEApp

    [edit]You can check this by running the command jar -tvf against the jar file that contains (or should contain) your main class.[/edit] [edit2]Or you could execute the .jar file directly by

    java -cp lib\AbsoluteLayout.jar;lib\appframework-1.0.3.jar;lib\beansbinding-1.2.1.jar;lib\swing-layout-1.0.4.jar;lib\swing-worker-1.1.jar -jar OmniIDE.jar

    assuming your main class is in the OmniIDE.jar file. [/edit2]

          Really not a helpful definition of a problem! What's the output of the jar -tvf command? Also what happens when you try with the -jar option? Please show exact commands and exact output in all cases. PS: I do not use NetBeans but Eclipse, and I know there are some bits of framework stuff that NetBeans adds to your package so it may well be that you cannot run the final package outside of the NetBeans environment. However, why that would be so is anyone's guess.

            I don't know how and why, but now everything is working!! I was typing away, and doing a clean + build like I normally do,and when I tried to run it again, it bombarded me with error messages indicating that a lot of my packages could not be found! Stumped, I cleaned and built it a couple of times, but failed miserably when I want to run it (really odd, since it was running successfully a couple of seconds ago.) So, I located the "broken" package, and renamed it to the package NetBeans expected. Cleaned and built it, ran it - it worked. So i though I might give executing the application a shot, and it worked! It's really odd though, since NetBeans should have complained right from the start, but for some reason, it didn't.:confused: Anyway, thanks for your help.

                    This is no simple Java homework Netbeans should provide a functionality to export your project in a proper way. There is no need to build some strange stuff. That's time waisted.

                      Clearly it's not always working so well, but I would still use NetBeans.

                      No, actually it's not! I have learned something from this entire experience, so I would not say it's time wasted! **Note:**If you don't want to help people, and you want to attack them for some strange and peculiar reason, rather keep quiet!

                        ..That's what I said - this does not look like a simple homework-project that can be simply launched from the command line. Why would you even want to work on the command line? All you're asking for is to run it outside of your IDE. So I recommend to export the project in the given way and that's it. Netbeans will do what is is supposed to do - build your application. No need to waste hours of time on fuzzy command line arguments. Better get a nice ice cream and watch Netbeans do the build :cool:
