Hello.java代码为：import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class Hello extends HttpServlet {
public void init(ServletConfig config)throws ServletException{
super.init(config);
}
public void service(HttpServletRequest request,HttpServletResponse response)throws IOException{
PrintWriter out=response.getWriter();
response.setContentType("text/html;charset=GB2312");
out.println("<html><body>");
out.println("Simple Servlet");
out.println("</body></html>");
}
}
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class Hello extends HttpServlet {
public void init(ServletConfig config)throws ServletException{
super.init(config);
}
public void service(HttpServletRequest request,HttpServletResponse response)throws IOException{
PrintWriter out=response.getWriter();
response.setContentType("text/html;charset=GB2312");
out.println("<html><body>");
out.println("Simple Servlet");
out.println("</body></html>");
}
}
要在web.xml中进行配置。
具体的配置例子网上有N多，多动动手！！！！！！
