hi !

i want to process a ITI-41 request and would like to know how big the request is in bytes before I store the documents to disk. Is there a way to get the content length ?

Hi,

You can simply count the bytes in the document input stream:
final ProvideAndRegisterDocumentSet request = Exchanges.getBody(exchange, ProvideAndRegisterDocumentSet.class);
final InputStream fileInputStream = request.getDocuments().get(0).getDataHandler().getInputStream();
final long documentSize;
try (final CountingOutputStream counter = new CountingOutputStream(new NullOutputStream())) {
    int b;
    while ((b = fileInputStream.read()) != -1) {
        counter.write(b);
    }
    documentSize = counter.getByteCount();
}

Kind regards,
Quentin

... and sometimes the content-length header ist present.
