hi
Here is the function that fails
/**
* Upload the given file to Fedora's upload interface via HTTP POST.
*
* @return the temporary id which can then be passed to API-M
requests as a
* URL. It will look like uploaded://123
*/
public String uploadFile(File file) throws IOException {
PostMethod post = null;
try {
// prepare the post method
post = new PostMethod(getUploadURL());
post.setDoAuthentication(true);
post.getParams().setParameter("Connection", "Keep-Alive");
// chunked encoding is not required by the Fedora server,
// but makes uploading very large files possible
post.setContentChunked(true);
// add the file part
Part[] parts = {new FilePart("file", file)};
post.setRequestEntity(new MultipartRequestEntity(parts, post
.getParams()));
// execute and get the response
int responseCode = getHttpClient().executeMethod(post);
String body = null;
try {
body = post.getResponseBodyAsString();
} catch (Exception e) {
LOG.warn("Error reading response body", e);
}
if (body == null) {
body = "[empty response body]";
}
body = body.trim();
if (responseCode != HttpStatus.SC_CREATED) {
throw new IOException("Upload failed: "
+ HttpStatus.getStatusText(responseCode) + ": "
+ replaceNewlines(body, " "));
} else {
return replaceNewlines(body, "");
}
} finally {
if (post != null) {
post.releaseConnection();
}
}
}
So, from the error we know that
HttpStatus.getStatusText(responseCode) gives "Bad Request"
and replaceNewlines(body, " ") gives "no data sent"
It seems that the Fedora instance does not accept the upload request for
some reason.

This actually proves nothing. You can create the APIA/N objects even for
a invalid repository.
I usually test by doing APIA.describeRepository(), as this changes
nothing, should always work, and will fail if there is a credentials or
connection problem.
