First I'd to say Hello for everyone and sory for my English.
I'm a newbie to jPTC, I compiled the applet example as well.

When I try to run applet in NetBeans I've got an error:
^{run:
java.lang.NoClassDefFoundError: java
Caused by: java.lang.ClassNotFoundException: java
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

Could not find the main class: java.  Program will exit.
Exception in thread "main" Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)}

What am I doing wrong?
