[Error] javac: target release 1.3 conflicts with default source release 1.5

Java 1.3에서 개발된 내용을 1.6으로 Upgrade 했을 경우 발생하는 Error입니다.

%TOMCAT_HOME%/conf/web.xml 파일을 변경해야 합니다.

   
        jsp
        org.apache.jasper.servlet.JspServlet
        
            fork
            false
        
        
            xpoweredBy
            false
        
        3
    

이렇게 바꾸면 됩니다.
