Within a Nuxeo 5.8 webengine site, I used to force Http Response to set Content-Disposition to “inline” for blob documents. I do it this way :

import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.ResponseBuilder;
...
Blob requestedBlob = (Blob) propertyFile.getValue();
ContentDisposition contentDisposition = ContentDisposition.type("inline").fileName(requestedFilename).creationDate(new Date()).build();;
requestedObject = Response.ok().header("Content-Disposition",contentDisposition).type(requestedBlob.getMimeType()).entity(requestedBlob).build();
return requestedObject;

This code doesn't work with LTS2015 plaform… Content-Disposition is always set to “attachment; filename=…” I saw that the artifact javax.ws.rs:jsr311-api used with Nuxeo 5.8 has been replaced by com.sun.jersey:jersey-server in LTS2015.

Here is my pom.xml:

....

Did I miss something?
