I am attempting to run VLCJ test jar from command line. VLCJ requires two external JARs
- jna.jar
- platform.jar
If I put those jars in the same directory as the executable jar I am attempting to run, I can run it successfully. However if I put them in their own directory and do the following:
java -classpath "C:\Users\Constantin\workspace\Java Libraries\JNA" -jar executable.jar
It cannot find a class from the JNA libraries. I am very new to Java, and my searches are not revealing a possible answer. So I was hoping someone could help answer:
How do I debug this? Why is it not finding the jar? Am I doing something wrong with my -classpath?
Thank you in advance!

Include the jars explicitly, or by using a simple
*
wildcard, but also include the executable jar. Specify the executable jar'smain
class on the command line (it will be in the manifest).(Where
com.foo.Bar
is the class containing themain
method, the app entry point.)See the Java options docs -- once
jar
is specified, all other classpath information is discarded and the jar you specify must contain all the user classes.Unrelated, but I always try to avoid paths with spaces in them on Windows. Well, everywhere, but particularly when dealing with Java-related stuff. It should work, and generally does, but there are edge cases when it doesn't (I'm looking at you, some versions of some app servers).
