package coreservlets;
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class _Net extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
//String searchString = response.encodeURL("Problem");
//问题原因:
String searchString = URLEncoder.encode("welcom");
//out.println(searchString + "OK");
out.println("OK");
}
}
提示出错为:
Note:_Net.java uses or overrides a deprecated API.
Note:Recompile with -deprecation for details.
路径调置正确..

use
encode public static String encode(String s,
String enc)
throws UnsupportedEncodingException
Translates a string into application/x-www-form-urlencoded format using a specific encoding scheme. This method uses the supplied encoding scheme to obtain the bytes for unsafe characters.
Note: The World Wide Web Consortium Recommendation states that UTF-8 should be used. Not doing so may introduce incompatibilites.
Parameters:s - String to be translated.enc - The name of a supported character encoding.
Returns:the translated String.
Throws: UnsupportedEncodingException - If the named encoding is not supported
Since:1.4
