Spring HttpRequestHandler multifile download

I try to change this one-file download to multi-files download one after one, not in zip. Every time I use this code, it downloads only first file (but the loop continues).
I think it's because of
httpServletResponse.setContentType(mimeType);
I've tried to solve this in some other ways, but nothing has worked.
#Override
public void handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
List<Example> examples = exampleService.findAll();
for (Example example : examples) {
try {
Blob blob = new SerialBlob(example.getFileContent());
InputStream inputStream = blob.getBinaryStream();
int fileLength = inputStream.available();
String mimeType = example.getContentType();
if (mimeType == null) {
mimeType = "application/octet-stream";
}
httpServletResponse.setContentType(mimeType);
httpServletResponse.setContentLength(fileLength);
String headerKey = "Content-Disposition";
String headerValue = String.format("attachment; filename=\"%s\"", example.getFileName());
httpServletResponse.setHeader(headerKey, headerValue);
OutputStream outputStream = httpServletResponse.getOutputStream();
byte[] buffer = new byte[4096];
int bytesRead = -1;
while ((bytesRead = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, bytesRead);
}
inputStream.close();
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}

Using relative path to store the uploaded file in java using Jersey

I am able to save image file in c://temp/images locally. But I want it in Project folder itself. Here is my code
#Path("/files")
public class FileUpload {
#POST
#Path("/upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
#FormDataParam("file") InputStream uploadedInputStream,
#FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "C://temp/images" + fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = uploadedFileLocation;
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
When I tried to replace file location with /resources/Images/,I am getting file not found exception.

try {
int read = 0;
byte[] bytes = new byte[1024];
outpuStream = new FileOutputStream(new File(filePath));
while ((read = fis.read(bytes)) != -1) {

How to fix this issue? Any help will be greatly appreciated!!!

Upload file via streaming using Jersey 2

I am trying to create a file upload API using Jersey. I would like to obtain details about the upload progress in the server side (is it possible?). Searching the web, the suggestion was to use stream to transfer the file. But... even was described below, the server just to execute the "putFile" method after the file arrives completely. Another problem is that these code only works to small files, when I try a file greater than 40mb
#Path("/file")
public class LargeUpload {
private static final String SERVER_UPLOAD_LOCATION_FOLDER = "/Users/diego/Documents/uploads/";
#PUT
#Path("/upload/{attachmentName}")
#Consumes(MediaType.APPLICATION_OCTET_STREAM)
public Response putFile(#PathParam("attachmentName") String attachmentName,
InputStream fileInputStream) throws Throwable {
String filePath = SERVER_UPLOAD_LOCATION_FOLDER + attachmentName;
saveFile(fileInputStream, filePath);
String output = "File saved to server location : ";
return Response.status(200).entity(output).build();
}
// save uploaded file to a defined location on the server
private void saveFile(InputStream uploadedInputStream, String serverLocation) {
try {
OutputStream outpuStream = new FileOutputStream(new File(
serverLocation));
int read = 0;
byte[] bytes = new byte[1024];
outpuStream = new FileOutputStream(new File(serverLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
outpuStream.write(bytes, 0, read);
}
outpuStream.flush();
outpuStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws FileNotFoundException {
ClientConfig config = new ClientConfig();
config.property(ClientProperties.CHUNKED_ENCODING_SIZE, 1024);
Client client = ClientBuilder.newClient(config);
File fileName = new File("/Users/diego/Movies/ff.mp4");
InputStream fileInStream = new FileInputStream(fileName);
String sContentDisposition = "attachment; filename=\"" + fileName.getName()+"\"";
Response response = client.target("http://localhost:8080").path("upload-controller/webapi/file/upload/"+fileName.getName()).
request(MediaType.APPLICATION_OCTET_STREAM).header("Content-Disposition", sContentDisposition).
put(Entity.entity(fileInStream, MediaType.APPLICATION_OCTET_STREAM));
System.out.println(response);
}

java development setting path in linux

i have development a simple webservices to upload a image to computer in linux. it have some problem the saving file location. when i summit the image, it become no response And i already import all require package.
#Path("/files")
public class V1_status {
/**
* Upload a File
*/
#POST
#Path("/upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public String uploadFile(
#FormDataParam("file") InputStream uploadedInputStream,
#FormDataParam("file") FormDataContentDisposition fileDetail){
saveToDisk(uploadedInputStream, fileDetail);
return"File uploaded successfully!";
}
// save uploaded file to a defined location on the server
private void saveToDisk(InputStream uploadedInputStream,FormDataContentDisposition fileDetail
) {
String uploadedFileLocation= "/home/fairlady/Pictures" +fileDetail.getFileName();
try {
OutputStream out= new FileOutputStream(new File(uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out= new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

In this line
String uploadedFileLocation= "/home/fairlady/Pictures" +fileDetail.getFileName();
you are missing a forward slash after Pictures
try
String uploadedFileLocation= "/home/fairlady/Pictures/"+fileDetail.getFileName();
