How do you send data to your application? Have you specified a Content-Disposition header for the respective parts?
We analysed a raw request via wireshark and it does look something like this: GET /api/someResource HTTP/1.1 Host: www.somewhere.com <http://www.somewhere.com/> … Content-Type: multipart/form-data; boundary=------------------------d9c950f09cd11bba --------------------------d9c950f09cd11bba Content-Disposition: form-data; name="dat1"; filename=„SomeFile.zip" Content-Type: application/octet-stream … --------------------------d9c950f09cd11bba Content-Disposition: form-data; name="dat2"; filename=„SomeOtherFile.zip" Content-Type: application/octet-stream … We use Camel 2.19.0 and the Undertow version Camel (camel-undertow-starter) and/or Spring-Boot (spring-boot-starter-undertow) includes their dependencies (undertow 1.4.13.FINAL). > Am 02.10.2017 um 04:25 schrieb Mark Webb [via Camel] > <ml+s465427n5814065...@n5.nabble.com>: > > Thanks for the example.
