Я пытаюсь прочитать XML в JSP и передать то же самое по сети, как char [] в апплет, но я получаю
java.io.StreamCorruptedException: неверный заголовок потока: 3C3F786D
мой JSP:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import = "java.util.*" %>
<%@ page import = "java.io.*" %>
<%@ page trimDirectiveWhitespaces="true" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<% String xmlname=(String)request.getAttribute("xmlname");
int ch;
System.out.println("the value of the xml is "+xmlname);
String filepath="C:/Users/ashutosh_k/idoc/docRuleTool/WebContent/data/Malaria.xml";
FileReader fis = new FileReader(new File(filepath));
char bin[] = new char[(int) new File(filepath).length()];
fis.read(bin);
response.getWriter().write(bin);
fis.close();
%>
</body>
</html>
