Class BeanValidatorForm
- DynaBean, Serializable
public class BeanValidatorForm
implements DynaBean, Serializable
Struts
validator ActionForm
backed by either a
DynaBean
or POJO JavaBean.
Passing a POJO JavaBean to the constructor will automatically create an associated
WrapDynaBean
. One use for this would be to migrate
view
objects from an existing system which, for the usual reasons, can't be changed to extend
.
This form is based on the standard struts ValidatorForm
for use with the
Validator framework and validates either using the name from the Struts
ActionMapping
or the ActionMapping
's path depending on
whether pathValidation
is true
or false
.
