You have to supply full class path when you are running your application, i.e. something like:

java -cp myapp.jar;jna.jar;platform.jar com.mycompany.MyMain

If you are using -jar option you should put all third party libraries to manifest.mf packaged into your jar under META-INF, i.e. add line like:

Class-Path: jna.jar platform.jar

to you manifest.

Pay attenition that you should use ; for windows command line, : for unix command line and space when writing class path in manifest.
