Hello?

간단히 Hello?를 출력하는 브라우저를 만들어봅시다.

 

 

 

1)

이클립스로 소스를 입력합니다.

 

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class Hello extends HttpServlet{	
	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		PrintWriter writer=resp.getWriter();
		writer.println("Hello?");
	}
}

 

2)

\Tomcat 7.0\webapps\JPcourse\WEB-INF\classes 폴더에 Hello.class를 저장합니다.

- Hello.class는 ..\bin 안에 있습니다.

 

 

 

3)

\Tomcat 7.0\webapps\JPcourse\WEB-INF\web.xml 을 다음과 같이 수정합니다.

  </servlet>

 <servlet-name>Hello</servlet-name>
 <url-pattern>/Hello</url-pattern>
  </servlet-mapping>

4)

크롬을 실행하여 주소표시줄에 http://localhost:8080/Hello 를 입력하여 실행합니다.

 

 

 

5)

브라우저에 Hello?가 뜬다면 정상입니다.

 

 

* xml이 몇몇 부분이 웹이라 정상적으로 보이지 않아서 첨부해두었습니다.
