Bom dia a Todos,
Estou tentando fazer uma validação do lado cliente utilizando Struts 2 mas ocorre o seguinte:

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.29 logs.
O XML da validação é este:

<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"

O estranho é:
Está funcionando para validação no servidor, quando na tag s:from, coloco o atributo validate=“false”.
Só ocorre o erro acima quando chamo a página jsp onde esta o formulário, se chamo diretamente pela action, funciona e é escrito o código javaScript na página e faz a validação.
Então a pergunta é, por que ocorre o erro acima quando chamo a página jsp que contém o formulário com o atributo validade = “true”, mas quando chamo pela action funciona e valida o campo?
