Error compiling simple example

[daveroberts]

There aren't any steps given to compile the simple example. Here is what I am trying:

$ javac -cp "lib/libthrift-0.9.2.jar:lib/slf4j-log4j12-1.5.8.jar:lib/slf4j-api-1.5.8.jar" -sourcepath "gen-java/tutorial" *.java
MultiplicationClient.java:28: error: cannot access MultiplicationService
  private static void perform(MultiplicationService.Client client) throws TException
                              ^
  bad source file: gen-java/tutorial/MultiplicationService.java
    file does not contain class MultiplicationService
    Please remove or make sure it appears in the correct subdirectory of the sourcepath.

Here are how my files are laid out:

$ ls -R *
MultiplicationClient.java  MultiplicationHandler.java  MultiplicationServer.java  multiplication.thrift

gen-java:
tutorial

gen-java/tutorial:
MultiplicationService.java

gen-py:
__init__.py  tutorial

gen-py/tutorial:
constants.py  __init__.py  MultiplicationService.py  MultiplicationService-remote  ttypes.py

lib:
libthrift-0.9.2.jar  slf4j-api-1.5.8.jar  slf4j-log4j12-1.5.8.jar

Any help is appreciated.
