The type Collection is not generic; it cannot be parameterized with arguments <? extends E>

아래와 같은 Exception이 발생하였음.

 

3시간정도를 고민하다가 Gauce 기술지원센터에 문의한 결과 10분만에 해결한 내용임.. ㅠ.ㅠ

해결책 -----------------

 

tomcat 5.5.X.X 버전에서 jsp 파일 include 요청시 compile Exception 발생하는 경우 해결방법입니다.


org.apache.jasper.JasperException: Unable to compile class for JSP

Generated servlet error:
The type Collection is not generic; it cannot be parameterized with arguments <? extends E>



해당 문제는 Gauce 문제가 아니라 톰캣에서만 발생하는 문제입니다.

톰켓 엔진에서 작성한 JSP파일을 서블렛 파일로 변경 후 컴파일 하는 도중에

JDK 1.5에서 추가된 generic 기능에 관련하여 컴파일을 하지 못하는 에러 입니다.

아래의 <servlet>태그를 web.xml 에 추가 함으로써 문제를 해결할 수 있습니다.
