You're using the library with none of its dependencies being available.

See here: http://code.google.com/p/bitcoinj/wiki/UsingMaven   - using Maven is probably the easiest way to get things set up. Otherwise you'll need to set your classpath to include Bouncy Castle (1.46), the protobufs library and if you want to follow git head also Guava and a few other things.

OK, but now i have other problem:

w.keychain.add(new ECKey());
