Name =name; } Public intGetage () {returnAge ; }

The framework can overcome the limitations of performing data verification programmatically in actionform bean. It allows struts to flexibly configure verification rules without programming.The validator framework mainly depends on two jar files: jakarta-oro.jar and commons-validator,.
