Getting MalformedChunkCodingException while downloading attachments
Hi All,
I am using HttpClient4.1 and jdk1.6.0_16, I am trying to download more than
1000 attachments using HttpClient in a program.
I used ThreadSafeClientConnManager for creating the connectionManager. When
i try downloading attachments and persisting the stream to DB, few are
failing with the following error
Caused by: 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)
at
org.apache.http.impl.io.ChunkedInputStream.read(ChunkedInputStream.java:167)
at
org.apache.http.impl.io.ChunkedInputStream.read(ChunkedInputStream.java:196)
at
org.apache.http.conn.EofSensorInputStream.read(EofSensorInputStream.java:155)
Actual piece of code for creation of HttpClient instance is:
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http",
workspaceMigrationConfigBean.getHttpPort(),
PlainSocketFactory.getSocketFactory()));
ClientConnectionManager cm = new
ThreadSafeClientConnManager(schemeRegistry);
HttpClient client = new DefaultHttpClient(cm);
If i retry to download only those failed attachments, they are persisted
properly. This issue is intermittent.
What could be the possible issue? Please help me.
Thanks in advance,
KiranKumar S.

Hi Oleg,
Thanks for your suggestion and i will try to do wire logging.
As i mentioned earlier this issue is intermittent and i am downloading the
files
using HttpClient's ThreadSafeClientConnManager.
Please let me know, is program bad or HttpClient has any issue with
ThreadSafeClientConnManager enabled?

Try running your code with wire logging enabled and see if data chunks
sent by the server are valid or not. See if there is some trailing data
at the end of the chunks, that is, if the actual length of a data chunk
is larger than the number stated in the chunk header.
