The DTD's are shipped in the Commons Validator jar - when the xml config
file(s) are parsed (using Digester) local copies of the DTD (i.e. the ones
in the jar) are registered and should be picked up and therefore it
shouldn't need to go over the net to get them. This problem usually occurs
when the DTD declaration in your validatior xml config files is incorrect.
You should have something like the following at the top of your validator
xml files...
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules
Configuration 1.1.3//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd";>
The above is for Version 1.1.3 of Commons Validator DTD - but the jar also
contains DTDs for 1.0, 1.0.1, and 1.1 - so declarations for them should also
work locally.
If your DTD declaration is correct, the other thing you might check is that
you have deployed the correct Commons Validator jar.

Subject: Problem with Struts Validator on machines without internet access
> Hi,
