Hello again,
I cannot give you straightforward answer,
try to do as little as possible. Create simple entity,
try to create new, delete some by key, createIfNotExists and similar
DAO methods. Do not put any nontrivial logic to this DAO.
Also make sure you entities have "right" key type and such,
your crearPartido method has somehow too many arguments try to make it
more simple.
step by step.
