Thanks for the information. I actually changed it after I sent the
e-mail and at the client side I get a 200 OK HTTP status.
I could not use the InputStream at the client side. I got a message that
I needed a sort of MessageBodyReader.
I got it to work with:
byte[] bytes = new byte[5000];
bytes = res.accept(
MediaType.APPLICATION_OCTET_STREAM_TYPE).post(
bytes.getClass(), formData);
but this piece of code assumes a certain maximum number of bytes. Is
there a way that I can use a buffered InputStream at the client's end
without having to write a MessageBoydReader sort of handler?
Thanks,
Gisella

Hi,
Change your resource method to be as follows:
ByteArrayOutputStream oStream = new ByteArrayOutputStream();
long checkSum = FileCompressionUtils.compressFiles(fileSet,
oStream, comment);
if (checkSum == 0L) {
resp = Response.noContent().build();
} else {
resp = Response.ok(
oStream.toByteArray(),
MediaType.APPLICATION_OCTET_STREAM_TYPE).build();
}
The writing of an OutputStream, nor a sub-class of, is not supported.
Thus you are getting a server-side error that states that the type
ByteArrayOutputStream is not supported.
You can utilize an InputStream, or a sub-class of, because information
can be obtained from it, namely the bytes, but that is not the case
for OutputStream.
I could add support specifically for ByteArrayOutputStream, but it is
not possible to support OutputStream in general (for reasons described
above).
Paul.
