dunque...io faccio così

> javac test.java -sourcepath D:\valerio\sorgenti\library\BST;D:\valerio\sorgent i\library\LinkedList;D:\valerio\sorgenti\library\N ode;D:\valerio\sorgenti\library\

e poi...

> java test -classpath D:\valerio\sorgenti\library\BST;D:\valerio\sorgent i\library\LinkedList;D:\valerio\sorgenti\library\N ode;D:\valerio\sorgenti\library\

Exception in thread "main" java.lang.NoClassDefFoundError: BST
at test.main(test.java:5)
> Execution finished.

perché per compilare tutto ok, ma per eseguire non trova le classi?
