# scenario:
PUTting a large file to a URL.
server reads Content-Length header and determines the file is to

server sends a 413 response.
server closes connection.
# my problem:
Since it is a large file the entity is not completely buffered, the
server closes the connection before HttpClient completes the request
transmission. I implemented a HttpMethodRetryHandler to handle this
but method.getStatusCode() throws a NullPointerException. I want to
be
able to read the response in order to determine what happened. Any
ideas?
Francesco,
This is a generic problem with classic (blocking) I/O in Java. There
is
simply no easy way of testing for pending input data while streaming
data out using blocking I/O. The only feasible solution to this
issue is
the use of non-blocking I/O, which has issues of its own.
Thanks this clears things up. I think i'll do some pattern matching on
the exception, document it and hope for the best.
Thanks,
Franco
