java - What is the best approach to upload a file using Jersey client? -

i want upload file (a zip file specific) jersey-backed rest server.

basically there 2 approaches (i mean using jersey client, otherwise 1 can use pure servlet api or various http clients) this:

1)

 webresource webresource = resource();     final file filetoupload = new file("d:/temp.zip");      final formdatamultipart multipart = new formdatamultipart();     if (filetoupload != null) {         multipart.bodypart(new filedatabodypart("file", filetoupload, mediatype.valueof("application/zip")));     }      final clientresponse clientresp = webresource.type(mediatype.multipart_form_data_type).post(         clientresponse.class, multipart);     system.out.println("response: " + clientresp.getclientresponsestatus()); 

2)

file filename = new file("d:/temp.zip");         inputstream fileinstream = new fileinputstream(filename);         string scontentdisposition = "attachment; filename=\"" + filename.getname() + "\"";         clientresponse response = resource().type(mediatype.application_octet_stream)             .header("content-disposition", scontentdisposition).post(clientresponse.class, fileinstream);         system.out.println("response: " + response.getclientresponsestatus()); 

for sake of completeness here server part:

@post     @path("/import")     @consumes({mediatype.multipart_form_data, mediatype.application_octet_stream})     public void uploadfile(file thefile) throws platformmanagerexception, ioexception {         ...     } 

so wondering difference between 2 clients?
1 use , why?
downside (for me) of using 1) approach adds dependency on jersey-multipart.jar (which additionally adds dependency on mimepull.jar) why want 2 jars in classpath if pure jersey client approach 2) works fine.
, maybe 1 general question whether there better way implement zip file upload, both client , server side...

approach 1 allows use multipart features, example, uploading multiple files @ same time, or adding form post.

in case can change server side signature to:

@post @path("upload") @consumes(mediatype.multipart_form_data) public response uploadmultipart(formdatamultipart multipart) throws ioexception { } 

i found had register multipartfeature in test client...

public fileuploadunittest extends jerseytest { @before     public void before() {         // support file upload test client         client().register(multipartfeature.class);      } } 

and server

public class application extends resourceconfig {     public application() {         register(multipartfeature.class);     } } 

thanks question, helped me write jersey file unit test!
