There should be more help for setting up the database URL.
I finally figured it out. For Oracle10g I used: jdbc:oracle:thin:@host:port:sid
For the jar I used C:\oracle\product\10.2.0\db_1\jdbc\lib\classes12.jar (others may need client_1 or something other than db_1)
I was trying to edit some data on a table. It would not let me. It said I need to have a primary key on a table in order to commit a change. I did not have a primary key on this table. That makes me sad :(
