How to create a Body for this Multipart POST request - http

Question

I ran a API request thorough postman and it ran successfully and this is its HTTP
POST //dummyendpoint/ HTTP/1.1
Host: dummyhost.com
Authorization: token="dummy_token"
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="config_enroll_settings"; filename="/C:/Users/SaurabhKumar/Desktop/config_enroll_settings.xml"
Content-Type: text/xml
(data)
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="usagePolicy"; filename="/C:/Users/SaurabhKumar/Desktop/usagePolicy.xml"
Content-Type: text/xml
(data)
----WebKitFormBoundary7MA4YWxkTrZu0gW
But then I am trying to achieve the same through JAXRS implementation I am getting 500 response code and when I checked the server side logs it said couldnt determine MIME boundary
This is my JAXRS interface I have explicitly added boundary but still it dosent works
#Consumes("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW")
#POST
#Path("/dummy_endpoint/{billingId}/")
public Object configureDeviceEnrollSettings(
#PathParam("billingId") String billingId,
#Multipart("multipartBody") MultipartBody multipartBody,
#HeaderParam("Authorization") String authorizationHeaderValue);
This is how I am calling this interface
Attachment configSettingsFile = new Attachment("config_enroll_settings", "multipart/form-data", new File("/C:/Users/SaurabhKumar/Desktop/config_enroll_settings.xml"));
Attachment usagePolicyFile = new Attachment("usagePolicy", "multipart/form-data", new File("/C:/Users/SaurabhKumar/Desktop/usagePolicy.xml"))
/*
I have tried this way also This way it resulted in exception
No serializer found for class java.io.FileDescriptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain:

File file1 = new File("/C:/Users/SaurabhKumar/Desktop/config_enroll_settings.xml");
ContentDisposition cd1 = new ContentDisposition("form-data; name=\"config_enroll_settings\"; filename=\"/C:/Users/SaurabhKumar/Desktop/config_enroll_settings.xml\"");
Attachment configSettingsFile = new Attachment("config_enroll_settings", new FileInputStream(file1), cd1);
File file2 =new File("/C:/Users/SaurabhKumar/Desktop/usagePolicy.xml");
ContentDisposition cd2 = new ContentDisposition("form-data; name=\"config_enroll_settings\"; filename=\"/C:/Users/SaurabhKumar/Desktop/usagePolicy.xml\"");
Attachment usagePolicyFile = new Attachment("usagePolicy", new FileInputStream(file2), cd2);
*/
List<Attachment> list=new LinkedList<>();
list.add(configSettingsFile);
list.add(usagePolicyFile);
MultipartBody body = new MultipartBody(list);
Object object = accountResource.configureDeviceEnrollSettings(billingId, body, "token=" + "\"" + authToken + "\"");
here is the stackTrace
