After attempting instantiating an implementation of Amazons S3 I get the following error at this line

String errorString = client.putObject(bucketName, key, artFile);

}

Posts with incomplete information are much more likely to be ignored.

Apache Core 4.0.1 does not contain the ImmutableHttpProcessor but 4.1.3 does and this is used by S3.
