Applet 调用servlet的问题

[bw1996]

请问，Applet中的button如何调用servlet中的发法

[剑事]

public String postURL(String URL,String param)
{
String result="";
try{
URL httpurl = new URL(URL);
HttpURLConnection httpConn = (HttpURLConnection)httpurl.openConnection();
httpConn.setDoOutput(true);
httpConn.setDoInput(true);
PrintWriter out = new PrintWriter(httpConn.getOutputStream());
out.print(param);
out.flush();
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(httpConn.getInputStream()));
String line;
while ((line = in.readLine())!= null)
{
result += line; //.substring(line.indexOf("|")+1)
}
in.close();
}catch(Exception e){
result="没有结果！"+e;
}
str=result;
System.out.println(URL);
return result;
}

使用xml通信

显示错误如下：
没有结果！java.io.IOException: Server returned HTTP response code: 405 for URL: http://localhost:7001/slTest1War/hi?name=Binwei

1、servlet的程序
public void doGet(HttpServletRequest request,
HttpServletResponse response){
try{
//String strName = (String)request.getAttribute("name");
System.out.println("HttpServlet*******************************");
String strName = request.getParameter("name");
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<body>");
out.println("<hl>");
out.println("hello1 "+strName+",here<br>");
out.println(new Date());
out.println("</hl>");
out.println("</body>");
out.println("</html>");
}catch(Exception ex){
ex.printStackTrace();
}
}
单独运行applet和servlet都正常
2、还有在我把url改成www.google.com的时候，显示Applet不能访问的错误，我想知道，以后我的applet和servlet如果不在同一台机器上的时候，会不会出现同样的问题

applet和servloet不在同一个war里，但是在同一个Web Application Modules不知跟这个有什么关系啊
