Thanks very much for your response.  That helps.  I'll follow the steps you have outlined and let you know what happens.

I don't see you are trying to compile the source for torque, just use the tar.gz 
files. You need to download torque-3.1.tar.gz and torque-gen-3.1.tar.gz. Extract 
them to two separate directories. Then move all files from torque-3.1 to 
torque-gen-3.1 and DONT overwrite any files that are already there om 
torque-gen-3.1. This should get you set up to use the examples provided at 
various tutorials. torque-gen-3.1 is the part which generates the java code for 
the tables you define in the schema.xml file, where as torque-3.1 is the part 
needed to actually compile and execute the generated java files. You could 
compare torque-3.1 to some kind of runtime libraries.

Read the tutorials from these pages -
http://db.apache.org/torque-31/user-guide.html
http://db.apache.org/torque-31/tutorial/step1.html

By the time you reach step 4 of the tutorial pages u should be able to 
understand what is going on.
