Am trying to generate Seam entities in Eclipse from a Postgres database.

Installed Helios, added JBoss Tools.

Have set up a new Seam project. Within the Hibernate settings, I have a database connection which points to a local version of Postgres 8.4. Testing the connection in the Hibernate settings works OK.

When I try and generate Seam entities from the database by doing the following:

Right-click on project -> New -> Other -> Seam Generate Entities -> Reverse engineer from database -> choose Postgres table using "Refresh" and "Include"

... I get an error saying:

Can't generate seam entities
org.hibernate.tool.hbm2x.ExporterException: File pattern not set on class org.hibernate.tool.hbm2x.GenericExporter
File pattern not set on class org.hibernate.tool.hbm2x.GenericExporter
org.hibernate.tool.hbm2x.ExporterException: File pattern not set on class org.hibernate.tool.hbm2x.GenericExporter
File pattern not set on class org.hibernate.tool.hbm2x.GenericExporter

The error log entry is as follows:
