다음과 같은 Struts 에러가 떨어지면 struts-config.xml 값의
<form-bean> 값이나
<action path=""> 에 해당하는 것이 매치가 안되는 것이다.
이번에 프로젝트 하면서 struts-config.xml 값이 제대로 설정 되었는데, 미치도록 이런 에러가 떨어져서 봤더니만..

jsp 와 classes vs image, html 분리시에 image 쪽에 제대로 복사가 안되어서 struts-config.xml 에서 action 값을 찾느라고 계속 호출해서 난 것이다.


다음과 같이 AbstractExcep 나 ExceptionCatcher  에러가 떨어지면,
sturcts-config.xml 파일을 잘 확인 해 볼것!
