    [Eclipse] Creating Runnable JAR file

    Hellow
    I have some problem with creating runnable JAR file in Eclipse. I made a class which use JMF library and I added this library in Eclipse (Build Path -> Configure Build Path -> Libraries -> Add External JARs -> and I pointed out locations of the required libraries (JMF.jar). When I compile and run my application in Eclipse everything is working properly and my problems start when I want to make a JAR file.

    I was searching in internet and couldn't find the solution of my probleme.

    I create a JAR file following by this steps: Export -> Runnable JAR file. The JAR is created but when I double click on it to opent it there is nothing happens. I tried to run it of the console (java -jar MYJARFILE.jar) and I get the following message:
    Code:
    Exception in thread "main" java.util.NoSuchElementException
            at java.util.Vector.firstElement(Unknown Source)
            at VideoTransmisja.<init>(VideoTransmisja.java:62)
            at VideoTransmisja.main(VideoTransmisja.java:349)
    It seams to be a problem with using JMF library.



    Next I tried to create by: Export -> JAR file in two ways "generate the manifest file" and "use existing manifest from workspace" and the problem was the same :/

    my manifest file:
    Code:
    Manifest-Version: 1.0
    Class-Path: jmf.jar
    Main-Class: VideoTransmisja
    Could someone help me please? I was trying to solve this probleme whole day

    I don't know if I correclty create my manifest file and if I could add jar library to creating jar file?

    Did you remember to select the radio button to package all required jars into your runnable jar?

    If using your own manifest approach the JMF.jar must be on the in the same directory as your jar.
