OCM: Object Manager, buildMapper return void not Mapper

[muriel elhaik]

Hi,

I think there is something wrong in the code to initialize correctly the 
Object Manager find in this page :
http://jackrabbit.apache.org/ocm/engine-introduction.html
// 3. Initialize the PersistenceManager dependencies
Mapper mapper = new DigesterMapperImpl(files).buildMapper();

But as it is in the src, buildMapper is returning a void and not a Mapper

Has anybody already noticed it?

Regards
Muriel
