JPA- dynamically create entity manager with JTA transaction type -

i have few databases same tables structure, each separate different language. use jpa jta transaction type. i'd create dynamically new connection database (from appliction level) when add new language (new database). know how create new entity manager resources_local transaciton type. possible jta?

i think have design flaw makes more complicated is. if have choice, best thing do, although requires work, internationalize database. shortly, add "language" column appropriate , have 1 database everything. when select bits you're interested in 1 language, add language restriction clause.

what asking quite complicated implement , maintain.
