Mark Struberg commented on MEECROWAVE-49: ----------------------------------------- Yes, will create a separate ticket for it. The problem I see is that isWriteable does *not* get Response! It seems that in case of returning a Response, CXF examines the content and this is the type you get in isWritable. So even for Response.ok("bla".getBytes()).build(); we are back to a byte[] in isWritable. Not sure if this was that way ever since though... > Returning a binary leads to nullpointers > ---------------------------------------- > > Key: MEECROWAVE-49 > URL: https://issues.apache.org/jira/browse/MEECROWAVE-49 > Project: Meecrowave > Issue Type: Bug > Affects Versions: 0.3.1 > Reporter: Mark Struberg > Assignee: Mark Struberg > Fix For: 0.4.0 > > > Currently Meecrowave tries to serve too much mime types via Johnzon.
