java - Returning both image and JSON in multipart response with Jersey -

i'm learning jersey trying create rest service receives image client, processes image , returns new image additional information (i.e., processing details).

so far, uploading works fine. i'm concerned creating response. i'm thinking of creating multipart response contains new image in 1 bodypart while adding json string (that contains additional info) body part. wasn't successful. code follows:

        file image = process(oldimage);         info info = getinfo();         string jsonstr = tojson(info);          mimemultipart multipart = new mimemultipart();          mimebodypart imagepart = new mimebodypart();         imagepart.setcontent(files.readallbytes(image.topath()), mediatype.application_octet_stream);          mimebodypart jsonpart = new mimebodypart();         jsonpart.setcontent(jsonstr, mediatype.application_json);          multipart.addbodypart(imagepart);         multipart.addbodypart(jsonpart);         return response.ok(multipart, "multipart/mixed").build(); 

i received error message follows:

messagebodywriter not found media type=multipart/mixed, type=class com.sun.xml.internal.messaging.saaj.packaging.mime.internet.mimemultipart, generictype=class com.sun.xml.internal.messaging.saaj.packaging.mime.internet.mimemultipart. 

i've been searching while haven't found anyway fix it. great of can pointing out what's wrong code , should approach take regarding issue.

i think com.sun.xml.internal.messaging.saaj.packaging.mime.internet.mimemultipart not class want.

jersey 2.x

for jersey 2.x, use multipart class org.glassfish.jersey.media.multipart package.

to use multipart features need add jersey-media-multipart module pom.xml file:

<dependency>     <groupid>org.glassfish.jersey.media</groupid>     <artifactid>jersey-media-multipart</artifactid>     <version>2.22.2</version> </dependency> 

and don't forget registering multipartfeature:

final application application = new resourceconfig()     .packages("org.glassfish.jersey.examples.multipart")     .register(multipartfeature.class) 

there's example of multipart request on jersey github repository.

for more details, have @ jersey 2.x documentation.

jersey 1.x

for old jersey 1.x, can use multipart class com.sun.jersey.multipart package.

the jersey-multipart dependecy necessary:

<dependency>     <groupid>com.sun.jersey.contribs</groupid>     <artifactid>jersey-multipart</artifactid>     <version>1.19.1</version> </dependency>
