httpclient 从服务端读取大文件

[木木水夕]

使用httpclient向服务端发送xml文件，然后服务端经过解析后在发送修改后的xml文件给客户端，现有一问题：当xml文件小的时候一百多K，没有问题，但是当xml为1M时客户端就抛出异常，服务端可以接收到完整的xml内容
异常如下：
Exception in thread "main" org.apache.http.MalformedChunkCodingException: Unexpected content at the end of chunk
at org.apache.http.impl.io.ChunkedInputStream.getChunkSize(ChunkedInputStream.java:239)
at org.apache.http.impl.io.ChunkedInputStream.nextChunk(ChunkedInputStream.java:204)

关键代码：

httppost = new HttpPost(URL);
            	//请求超时
            	httpclient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, nTimeout);  
            	//读取超时
            	httpclient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, nTimeout);
            	//写入报文信息
            	reqEntity.addPart("body", body);
                httppost.setEntity(reqEntity);
                try {
					response = httpclient.execute(httppost);
				}  catch (IOException e) {
					System.out.println("read data timeout");
					continue;
				}  

        resEntity = response.getEntity();
        inputStream = resEntity.getContent();
        InputStreamReader reader = new InputStreamReader(inputStream ,
		"UTF-8");
		char[] buff = new char[1024];
		int length = 0;
		while ((length = reader.read(buff)) != -1) {
			String x = new String(buff, 0, length);
			System.out.println(x);
		}

int readCount = innerReader.ReadContentAsBase64(buffer, index, count);

if (readCount == 0)

{

//GetReaderFromNextChunk will wait for chunks to be queued

//then set this.innerReader to the received message's reader

//it will throw TimeoutException if the next chunk is not received within specified timeout

GetReaderFromNextChunk(receiveTimeout);

if (!isLastChunk)

{

readCount = innerReader.ReadContentAsBase64(buffer,

index, count);

if (readCount == 0)

{

throw new CommunicationException("Received chunk contains no data");

}

else

{

return readCount;

}

}

else //lastChunk

{

return 0;

}

}

else

{

return readCount;

}

StringEntity entitys = new StringEntity(jsonObject.toString());
entitys.setContentType("application/json");
entitys.setChunked(true);

[我嘞个去]

没遇见过这种问题，友情帮顶。。。。

能否解释的清楚点？

我lz返回的是xml，你怎么设成json了？
entitys.setContentType("text/xml");
entitys.setChunked(true);

呵呵，不好意思，直接拷贝代码的，忘了改了

[木木水夕]

搞定。。。。。是我服务端返回时写的不。。。
服务端我是直接使用：
PrintWriter out = resp.getWriter();
out.write(s);
用下面这个就不会出错：
OutputStream out = resp.getOutputStream();
OutputStreamWriter ouputw = new OutputStreamWriter(out,"UTF-8");
String str2 = sb.toString();
ouputw.write(str2);
