java - Hot to write a custom validator with apache bval -

-

i using bean-validation apache bval implementation. (i not want use hibernate-validation or oval, because have dependencies.)

first question: bval still maintained or orphaned?

second question: possible implement custom validators using bval? e.g. need validator file field validates, file exists, isreadable , file.

apache bval afaik compliant bean validation 1.0 means should able write portable custom constraints. however, bval not yet bean validation 1.1 compatible, meaning won't have executable constraints.

i don't know how active development atm. last release in september 2012 quite while back.

what concern hibernate validator or oval dependencies?
