java语句模拟表单提交，怎么做？？？？

可以使用Apache的http-client-common包来实现模拟Request

URL url = new URL ("http://www.some-side.com/some-page.jsp");
HttpURLConnection conn = url.openConnection ();
conn.connection ();
conn.setRequestMethod("POST");// 如果你想用get方法，这里改成GET
StringBuffer sb = new StringBuffer ();
sb.append ("Param1=Value1&Param2=Value2....");
OutputStream out = conn.getOutputStream ();
out.write (sb.toString ().getBytes ());

XMLHttpRequest
返回的东西是XML
