Indeed, I forgot to place xds-i before the adress... Thank you for noticing that !
It helped but I am still getting an error when trying to export. The error is :
2018-09-14 15:49:48,147 WARN [org.dcm4chee.arc.export.mgt.impl.ExportManagerMDB] (Thread-5 (ActiveMQ-client-global-threads)) Failed to process ActiveMQMessage[ID:0b4e1f4e-b825-11e8-b8fe-9829a67c3824]:PERSISTENT/ClientMessageImpl[messageID=281320368615, durable=true, address=jms.queue.Export3,userID=0b4e1f4e-b825-11e8-b8fe-9829a67c3824,properties=TypedProperties[AETitle=DCM4CHEE,RequesterUserID=127.0.0.1,__AMQ_CID=c28be650-b821-11e8-b8fe-9829a67c3824,StudyInstanceUID=1.3.51.0.7.99.2155959091.26807.877615593.0,ExporterID=XDS_Exporter,RequestURI=/dcm4chee-arc/aets/DCM4CHEE/rs/studies/1.3.51.0.7.99.2155959091.26807.877615593.0/export/XDS_Exporter,RequesterHostName=127.0.0.1]]: javax.xml.ws.soap.SOAPFaultException: Invalid Content Type Field in the Mime Message

So now I have a stupid question (i'm truly sorry).
What kind of files do I have to send to my XDS repository ? I am getting this error with dicom files containing images and KOS (that I generated with the tool mkkos in dcm4che).
I did read some stuff on XDS-i.b IHE profile but didn't foud this information very clear...
