newapp difficulties changing schema

["Michael C. Starkie" <mi...@michaelstarkie.com>]

re: turbine-2.1 on Linux.

It's taking me too long to learn how to create a new turbine application from scratch.  The only way to do this, as far as I can tell, is to re-engineer the sample "newapp" and learn as you go.

A particular problem exists for new users who want to modify the newapp-schema.xml file.  It seems that the torque utility has already created the peer java source files for the old schema (because the tutorial asks you to run "ant" in the tdk home directory as a first step)

If I modify the schema I get runtime exceptions when trying to do an insert because turbine is looking for a class or method that contains "Rfd", a reference to the primary key in the old schema.

If I remove the torque generated java files in the modules directory I can't even compile the newapp application.

It appears my only solution is to modify the torque generated files which defeats the purpose of using turbine in the first place.

WHAT DO I NEED TO DO TO SET UP TORQUE SO IT RECOGNIZES MY SCHEMA CHANGES?

-- or --

WHERE CAN I LEARN HOW TO CREATE A NEW TURBINE APP FROM SCRATCH?

thanks,
Mike

you removed the torque generated java files from the om directory?  What
about the *.class files in the class directory - get rid of those too.  Now
run an ant init from the build dir and it should work.
