I know it. I wrote own validator (extends
org.exolab.castor.xml.FieldValidator) and set it in constructor of
MyFooDescriptor:
public MyFooDescriptor() {
super();
//name is element of foo
XMLFieldDescriptorImpl fd =
(XMLFieldDescriptorImpl)getFieldDescriptor("name", null);
fd.setValidator(new CustomValidator());
}
But what to do to force validator, unmarshaler and marshaler to use MyFoo
instead of Foo (or Foo with MyFooDescriptor)? Foo is not root element!!
I tried:
ClassDescriptorResolverImpl cdr = new
ClassDescriptorResolverImpl();
cdr.associate(Foo.class, new MyFooDescriptor());
Unmarshaller un = new Unmarshaller(Document.class);
un.setResolver(cdr);
but it doesn't work.
And another problem. I must check value of another object in tree to check
is object validate. Is there any way to get parent object of field or
attribute?
thanks a lot
Marcin
