从动作脚本发送XML来的Servlet [英] Sending XML to Servlet from Action Script

问题描述

我有一个ActionScript文件发送XML到我的servlet。 我只得到输出空数组。任何人都知道究竟我做错了吗？ 输出是：

I have an ActionScript File sending XML to my servlet. I am only getting empty arrays on output. Anyone know what Exactly I'm doing wrong? output is:

java.io.StreamCorruptedException：无效的流头         在java.io.ObjectInputStream.readStreamHeader（ObjectInputStream.java:764）         在java.io.ObjectInputStream中。（ObjectInputStream.java:277）         在myDungeonAccessor.myDungeonAccessorServlet.doPost（myDungeonAccessorServlet.java:82）

java.io.StreamCorruptedException: invalid stream header at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:764) at java.io.ObjectInputStream.(ObjectInputStream.java:277) at myDungeonAccessor.myDungeonAccessorServlet.doPost(myDungeonAccessorServlet.java:82)

   package myDungeonAccessor;
      protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {    
try {
    System.out.println("HEADERS: " + request.getHeaderNames());
    ObjectInputStream in = new ObjectInputStream(request.getInputStream());
    System.out.println(in);
    ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());
   } catch(Exception e) {
       e.printStackTrace();
   }

异常

推荐答案

的System.out.println（）写到标准输出（通常结束了在服务器日志和/或IDE的控制台，如果有的话），而不是响应。写 response.getWriter（）代替。

System.out.println() writes to the stdout (which usually ends up in server logs and/or the IDE console, if any), not to the response. Write to response.getWriter() instead.

不过，我会建议使用 XStream的写fullworthy的Javabean到XML <一个HREF =HTTP：//xstream.$c$chaus.org/tutorial.html相对=nofollow>不劳而获

That said, I'd suggest to use XStream to write fullworthy Javabeans to XML without pains.

response.setContentType("text/xml");
response.setCharacterEncoding("UTF-8");
new XStream().toXML(bean, response.getOutputStream());
