I was told to add this to prevent external entity injection,

dbf.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);

But the link(http://apache.org/xml/features/disallow-doctype-decl) given is returning 404 error

I could not find any other alternative links for the current suggested link: http://apache.org/xml/features/disallow-doctype-decl

Is the link changed or updated?
