I have written a Rest Service in Jersey to upload a Multiple Files. As shown Below. But i want the attribute name i.e name="metadata" and name="file " in Restservice class.
Select XML file 1: <input type="file" **name="metadata"** size="45" accept=".xml" />
Select PDF file 2: <input type="file" **name="fileak**" size="45" accept=".pdf" />
Select XML file 1:
Select PDF file 2:
@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public Response uploadFile(
@FormDataParam("file") List<FormDataBodyPart> parts) {
for (FormDataBodyPart part : parts) {
FormDataContentDisposition disp = part
.getFormDataContentDisposition();
InputStream in = part.getValueAs(InputStream.class);
}
return Response.ok(" uploaded successfully !!").build();
}
FormDataContentDisposition only pulls the content type , file name from the form and not the input type name="" attribute.
Any help would be highly appreciated.

The thing is, the value in @FormDataParam("file") is the name. You use this when you want all the parts extracted by name. For instance you can have
post(@FormDataParam("metadata") InputStream metaIn,
@FormDataParam("metadata") FormDataContentDisposition metaFcd,
@FormDataParam("fileak") InputStream fileakIn,
@FormDataParam("fileak") FormDataContentDisposition fileakFcd) {
}
But if you want to iterate through all the parts yourself, you should use FormDataMultiPart instead of List<FormDataBodyPart>. You can get the map, with the name as the key. Also the name is provided in the FormDataBodyPart.getName(). For example
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadAsset(FormDataMultiPart multipart) {
Map<String, List<FormDataBodyPart>> map = multipart.getFields();
for (Map.Entry<String, List<FormDataBodyPart>> entry : map.entrySet()) {
for (FormDataBodyPart part : entry.getValue()) {
InputStream in = part.getEntityAs(InputStream.class);
String name = part.getName();
System.out.println("--- name: " + name);
}
}
return Response.ok("cool upload").build();
}
The point is that it is pretty pointless to try and obtain the name (programmatically) if you are going to use @FormDataParam annatotion, because you are ultimately already hard coding the name (in the annotation value), so you already know it.
