how to reference classes in jar file

[redsss]

I'm trying to run a java example I downloaded from

http://www.jsresources.org/apps/midiplayer.html

I must be doing something wrong because I get the error

Exception in thread "main" java.lang.NoClassDefFoundError: org/jsresources/apps/jmvp/manager/ResourceManager

when I execute it like so:

java -classpath jmvp-2003-06-20.jar -jar midiplayer-2003-06-20.jar

I checked the far file and found that class in the given path. What am I doing wrong?

I don't think there's anything wrong with what you typed. I took the liberty of downloading the file and extracing the jar file and browsed down to the path it's looking for. The person that created the jar file must have made a mistake in entering the locations of the imported classes, since there is no /appa/jmvp directory in the jar file.

Double-check yours again, but I downloaded the same version you have and it was missing that directory.

You sure? I opened the file jmvp-2003-06-20.jar with ark (a linux version of winzip) and see a file with the path org/jsresources/apps/jmvp/manager/ResourceManager.class with an original filesize of 3115 bytes.

That's not a ClassNotFoundException but a NoClassDefFound error.

Looks like you need more classes on your classpath.
