Kepler uses Ptolemy II as its underlying execution engine.
A Ptolemy II model implemented in Java may be found at
kepler/ptolemy/src/ptolemy/domains/sdf/demo/Butterfly/Butterfly.java

See the Butterfly example above.

The Kepler Developer FAQ is a good jumping off point, see

If you have a parameter named myParameter, call

      myParameter.setExpression("2.0");

See the hello-world example above for other information.

To export a model as xml, if you have a ptolemy.kernel.util.NamedObj 
named myModel that contains your model, call

      System.out.println(myModel.toplevel().exportMoML());

I don't manage the kepler-project.org, so I can't address the missing 
javadoc problem.
There is a copy of the javadocs at

http://chess.eecs.berkeley.edu/ptexternal/kepler/javadoc/overview-frame.html

To create a local copy of the javadocs, install Kepler from sources, see
https://kepler-project.org/developers/teams/build/documentation/build-system-instructions

Then run
    cd kepler/build-area
    ant javadoc

The javadocs should appear in kepler/javadoc
