Bedework Development: Getting Started
First be familiar with the most current Bedework Manual
Be Prepared (for schema changes)
Next, remember that changes to the source may have changed the schema. You need to be prepared to either scrap your test data and start again with a fresh database or ttempt to save and restore your data using the dump/restore utilities. In general, the dump/restore approach will work but between releases inconsitencies and ommissions can occur.
To take the scrap and restart approach, cd into the hsql database directory and destory the "demo" directory.
Then, restart hsqldb and use the dump/restore tool to do a schema-export and an initdb.
These steps are fully explained in the deployment manual.
