Hi guys,

I'm trying to run SchemaExport with ant and I keep getting a java.lang.NullPointerException. It seems to me that SchemaExport is looking for some foreign keys in the mapping file. I've commented out all the other mappings to simplify the schema generation but it doesn't seem to matter which mapping file i use. It still generates the same issue. Can you please help? Many thanks in advance.
