예외가 발생 다음과 같은 예외를 받고. 유효성 검사 프레임 워크는 이전 버전에서 제대로 작동했습니다. 이 문제를 해결하는 데 도움을주십시오.

Answer 1

이 PUBLIC ID 시도 :

<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN" 
     "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd"> 

Answer 2

가 해결책을 발견!

우리는 classname-method-validation.xml 파일과 validators.xml 파일을 사용하고 있습니다. 사용하는 동안, 또한

<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator Definition 1.0//EN" 
"http://struts.apache.org/dtds/xwork-validator-definition-1.0.dtd"> 

:

<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN" 
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd"> 

및 validators.xml에

는 아래의 문서 유형을 사용

클래스 명 메소드-validation.xml에서

, 아래와 같은 문서 형식을 수득 정규식에 대한 정규식, 우리는 expression 같은 매개 변수 이름을 사용했다. regexExpression으로 변경해야합니다.

예 :

<field-validator type="regex" short-circuit="true"> 
    <param name="regexExpression"><![CDATA[^(?!0{9})(\d{9})$]]> 
    </param> 
    <message>${getText("ft.accounts.alert.validRoutingNumber")}</message></field-validator>
