JSP/Servlet - 서블릿 테스트시 HTTP Status 500 - Error instantiating servlet class 발생시

해결책

web.xml 파일에서

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="3.0">

    <servlet>

        <servlet-name>hundred-servlet</servlet-name>

        <servlet-class>com.exam.ch1.HundredServlet</servlet-class>

    </servlet>

    <servlet-mapping>

        <servlet-name>hundred-servlet</servlet-name>

        <url-pattern>/hundred/mypattern</url-pattern>

    </servlet-mapping>

</web-app>

위와 같이 servlet-class에서 패키지명을 반드시 써줘야 합니다.
