java - extract file name from content disposition -

-

my payload has content-disposition field. trying upload bpmn file. @ backend need parse input stream , extract file name. not able find solution of this. using jesrey rest.

i tried :

@post @consumes(mediatype.multipart_form_data) @produces(mediatype.application_json) public response addworkflowschema(@formdataparam("bpmndata") inputstream uploadedinputstream,          string filename,         @context httpservletrequest request)

to whole payload data. if remove formdataparam ma getting request body.

reuqest payload : 

------webkitformboundary8ccb878tyzkse9go content-disposition: form-data; name="bpmndata"; filename="process.bpmn" content-type: application/octet-stream   ------webkitformboundary8ccb878tyzkse9go--

i need filename content-disposition. how can this.

just inject formdatacontentdisposition also, , file name that. 

public response addworkflowschema(                        @formdataparam("bpmndata") inputstream in,                        @formdataparam("bpmndata") formdatacontentdisposition fdc) {      string filename = fdc.getfilename(); }

the inputstream content of file part. won't include headers, don't need extract it.
