Hi Adam,

Thanks for writing! I think your problem was caused by a bug in my
'JCVSReport' shell script -- I forgot to include the "src" directory
in the classpath. The latest version of JCVSReport (announced on the
bulletin board on Mar. 23) includes this fix and also a fix to the
database.ddl file to fix a bug in Bloof.

This is what the JCVSReport shell script should look like:
java -cp "dest:src:lib/JCVSReport.jar" ca.utoronto.JCVSReport.Presentation $*

(Notice that the 'src' directory is included in there before the
JCVSReport.jar directory, so if my shell script is working propertly, it
should use your database.ddl file in src/net/sf/bloof/db)

To test whether modifying the database.ddl file is working, try the
following commands:
mv src/net/sf/bloof/db/database.ddl src/net/sf/bloof/db/database.bak
echo BROKEN SQL STATEMENT > src/net/sf/bloof/db/database.ddl

Let me know whether that works for you. Hope it helps!

Cheers,

David

P.S. Are you using Eclipse for development? If so, it is often easier
to use Eclipse's facilities for compilation rather than my Ant script.
