Yasser Zamani commented on WW-4841:
-----------------------------------
What I see at [Validation|https://struts.apache.org/docs/validation.html] does
not have the word {{Config}} and is:
{code:xml}
<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd";>
{code}
Also, Struts will try to use locally provided DTDs before fetching them over
Internet but if it happens it means you should see such log message:
{nofomat}Local DTD is missing for publicID: .... - defined mappings:
....{nofomat}
and it means you are using wrong PublicID that doesn't match any of the Struts
DTDs
