Hi Jaroslav,
Ah, i think i know why. The problem is Jersey cannot set the boundary
parameter on the content-type of the response.
Looking into the source code:
com.sun.jersey.client.apache.ApacheHttpClientHandler#170
if (cr.getEntity() != null) {
final RequestEntityWriter re =
getRequestEntityWriter(cr);
final Integer chunkedEncodingSize =
(Integer
)props.get(ApacheHttpClientConfig.PROPERTY_CHUNKED_ENCODING_SIZE);
if (chunkedEncodingSize != null) {
// There doesn't seems to be a way to set the
chunk size.
entMethod.setContentChunked(true);
// It is not possible for a MessageBodyWriter to
modify
// the set of headers before writing out any
bytes to
// the OutputStream
// This makes it impossible to use the multipart
// writer that modifies the content type to add a
boundary
// parameter
writeOutBoundHeaders(cr.getMetadata(), method);
// Do not buffer the request entity when chunked
encoding is
// set
entMethod.setRequestEntity(new RequestEntity() {
public boolean isRepeatable() {
return false;
}
public void writeRequest(OutputStream out)
throws IOException {
re.writeRequestEntity(out);
}
public long getContentLength() {
return re.getSize();
}
public String getContentType() {
return re.getMediaType().toString();
}
});
I need to investigate whether it is possible to set the headers before
any bytes are written to the OutputStream passed into
RequestEntity.writeRequest. I suspect not, and if so it is going to
require some additional functionality to make this work with the
Apache HTTP client.
Can you log an issue.
In the interim you should be able to use the HttpURLConnection support.
Paul.
