JSP의 라인수가 너무 길어서 톰캣 오류가 발생하는 경우!

1. 오류로그

원인 : Java Method는 64KB보다 커질 수 없음.

2. 해결방안

1. web.xml에 아래 코드를 삽입한다.

       <servlet>
           <servlet-name>jsp</servlet-name>
           <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
           <init-param>
               <param-name>mappedfile</param-name>
               <param-value>false</param-value>
           </init-param>
       </servlet>
   ​
   

2. 실제적인 해결방안으로는 파일을 쪼개기위해 include를 사용하는 것을 추천한다.
