> I am using a read-only db in a zip file with Derby in embedded mode.  I ran an importer
against it which basically just harvests info from DatabaseMetaData and got an error on several
methods like this one.  The method in question here is DatabaseMetaData.getTableTypes(). 
The same thing seems to happen on other methods I've tried as well (getCatalogs, getProcedures,
etc).

>         ResultSet rs = dbmd.getTableTypes();
