Syntax error on token "}", delete this token 이런 오류였는데...

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

public class CodeReturn extends HttpServlet{
 public void doGet(HttpServletRequest request,HttpServletResponse)throws IOException,ServletException{
  response.setContentType("application/jar");
  ServletContent ctx = getServletContext();
  InputStream is = ctx.getResourceAsStream("/bookCode.jar");
  int read = 0;
  byte[] bytes = new byte[1024];
  OutputStream os = response.getOutputStream();
  while((read = is.read(bytes)) !=-1){
   os.write(bytes,0,read);
  }
  os.flush();
  os.close();
 }
}

소스에서 다음과 같은 오류가 났다.
찾아보니...

 public void doGet(HttpServletRequest request,HttpServletResponse)throws IOException,ServletException{
에서
doGet(HttpServletRequest request,HttpServletResponse response)
라고 썼어야 했다.ㅋㅋㅋ
근데 왜 Syntax error on token "}", delete this token 이게 뜨지?;;;
