Looks like the table already exists. If you are using HSQLDB (the default), then bring down the app server and remove the directory server/default/data. Then bring the app server up and try it again. By the way, HSQLDB puts its database at server/default/deploy/hypersonic.localDB.script, so by removing the data directory your are deleting the database.
