Tomahawk + seam이 작동하지 않습니다.

그래서 Seam Project가 있고 Tomahawk 1.2를 통합하려고합니다. 나는 WebInf/lib에있는 tomahawk12.jar을 복사 한 난 web.xml에 다음과 같은 구성이 있습니다Tomahawk + seam이 작동하지 않습니다.

<filter> 
    <filter-name>MyFacesExtensionsFilter</filter-name> 
    <filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class> 
    <init-param> 
     <param-name>maxFileSize</param-name> 
     <param-value>20m</param-value> 
    </init-param> 
</filter> 

<filter-mapping> 
    <filter-name>MyFacesExtensionsFilter</filter-name> 
    <servlet-name>Faces Servlet</servlet-name> 
</filter-mapping> 

<filter-mapping> 
    <filter-name>MyFacesExtensionsFilter</filter-name> 
    <url-pattern>/faces/myFacesExtensionResource/*</url-pattern> 
</filter-mapping> 
<filter-mapping> 
    <filter-name>MyFacesExtensionsFilter</filter-name> 
    <url-pattern>*.seam</url-pattern> 
</filter-mapping>

내가 스케줄러를 사용하려면를하지만 다음과 같은 예외가 얻을 :

"java.lang.LinkageError : loader constraint violation"은 일반적으로 클래스 경로에 문제가 있음을 의미합니다. 중복 된 jar (이 경우 tomahawk jar)에 대한 클래스 경로를 확인하십시오.
