bulid it;there exception at the following:

while...

BUILD FAILED
J:\middlegen\samples\build.xml:200: middlegen.MiddlegenException: Middlegen succ
essfully connected to the database, but couldn't find any tables. Perhaps the sp
ecified schema or catalog is wrong? -Or maybe there aren't any tables in the dat
abase at all?
thanks for any hints!

The message is stating that it could no find any tables.
Ask yourself:

Have you setup the JDBC driver correctly?
Does the JDBC driver support meta data ?

Mostly these have occured when people have not setup the JDBC connection correctly or are using beta or buggy JDBC drivers. I would suggest you try coding a small app and get meta data from a JDBC connection and see if it works.

run "ant create-tables" first for the sample. Then run "ant"
