Mapeando dtd para meus próprios .xml

Front-end
#1

Bom dia amigos!
Eu fiz um arquivo dtd para validar meu arquivo xml e coloque-o na pasta WEB-IFN/dtd da minha aplicação. Como faço para mapear meu .dtd dentro do meu .xml de forma que eu possa rodar a aplicação em qualquer servidor?

Meu xml:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE mytag SYSTEM "dtd/myfile-config.dtd">
<mytag>
...
</mytag>

Erro retornado pelo tomcat:

Tem ctz q o caminho do DTD é este??? :?:

#3

Pois é, eu gostaria de colocar algo assim:

Mas não sei fazer isso, não sei se dá para colocar uma variável aí.
Navegando nas dicas de nossos amigos eu encontrei http://www.guj.com.br/posts/list/10151.java, a qual eu segui a sugestão, deixando da seguinte forma:

<!DOCTYPE parameters SYSTEM "File://dtd/myfile-config.dtd">

Mas aí o erro muda para:

java.net.UnknownHostException: dtd
