An alternative is to get it from the DbUnit connection like this:

IDataSet databaseDataSet = connection.createDataSet();
ITableMetaData metaData = databaseDataSet.getTableMetaData("SCOTT");

Why? I don't really remember why but this constructor is likely to change 
in the future. In fact it has already changed in the past but been 
reverted to its original signature except for public modifier. Getting the 
metadata from the connection should shield you from such changes. 

Tables' metadata are cached in the DbUnit connection, reusing the same 
connection thorough your suite is reputed more efficient. BTW, 
DefaultDataSet has new methods and you should found it easier to use.
