I made minor changes to the build.xml file, specifically the exportddl target so that it would update the standalone hsqldb database. I made the following changes.

[code]<target name="exportddl" depends="compiletest" description="Export the DDL to caveatemptor.ddl">
<schemaexport
config="${classes.dir}/hibernate.cfg.xml"
quiet="no"
text="no"
drop="no">
<!-- Previous attributes were set to yes, drop was not present -->
<!-- output="${basedir}/caveatemptor.ddl"
delimiter=";"/>-->
<fileset dir="${classes.dir}">
<include name="**/*.hbm.xml"/>
</fileset>
</schemaexport>
</target>[code]

It never actually makes it to the db update however, this is the output and exception:

[code]Buildfile: build.xml

BUILD FAILED
C:\my\Programming\Projects\caveatemptor\build.xml:111: Schema text failed: net.s
f.hibernate.MappingException: duplicate import: Bid[/code]

I can't tell if I've just screwed up settings for the database or if it's something else. Any ideas? I've seen where duplicate imports have occurred because of missing id's, but that's not the case with Bid.

I'm just getting into the book, but it's a godsend already.
Thanks in advance

Uhm, and if you run the build and test or export (to a file) without your changes, it works? I dont' really see what you have changed and I don't understand why (the tests automatically create/drop the database).

I use a task similar to the 'exportddl' task that uses the SchemaUpdateTask to make changes in the hsqldb standalone database.
When I use the default 'exportddl' task, which just sends output to file, yes it works. But when I change the settings for the SchemaUpdateTask,
    Changing 'quiet' to 'no'
    Changing 'text' to 'no'
    Adding attribute 'drop' set to 'no'
    Removing the 'output' attribute
    Removing the 'delimiter' attribute
    Adding the element 'fileset' and including the mapping files

It should then update the hsqldb, allowing me to open the HSQL Database Mananger and see/play with the tables.
When I do this, the SchemaUpdateTask complains about the Bid mapping file. The exception is a MappingException, the message states a duplicate import.
