i'm not sure files need show here solve problem, please :(

the currententitymanager null.

this part of code shows error logs:

@out(scope = scopetype.session)         entitymanager currententitymanager; 

the error quite clear, seam trying outject currententitymanager value unable because variable null. thus, need see why null (i presume because emf null or not opened).

you can instruct seam not complain when currententitymanager null (using required option of annotation). however, if not expect null, need check reason.

@in(required=false) @out(scope=scopetype.session, required=false) entitymanager currententitymanager; 

also, not clear why you're returning cem in function, , why you're not setting currententitymanager value of cem.
