I try to create a restful service that uploads a file. I followed the steps of:
http://examples.javacodegeeks.com/enterprise-java/rest/jersey/jersey-file-upload-example/
http://www.mkyong.com/webservices/jax-rs/file-upload-example-in-jersey/
But, when I upload a file (for example, a .pdf), the input FormDataMultiPart is always NULL and I don´t understand why. I use the libs "jersey-multipart" and "jersey-core". My code:
Restful service:
#Path("/reservation")
public class ReservationWs {
/** The Constant log. */
private static final Logger LOGGER = LoggerFactory.getLogger(ReservationWs.class.getName());
private static final String SERVER_UPLOAD_LOCATION_FOLDER = "C://opt/share/reservation/";
#POST
#Path("/upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
#FormDataParam("file") InputStream uploadedInputStream,
#FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = SERVER_UPLOAD_LOCATION_FOLDER
+ fileDetail.getFileName();
// save it
saveFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
#POST
#Path("/upload2")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile2(FormDataMultiPart form) {
FormDataBodyPart filePart = form.getField("file");
ContentDisposition headerOfFilePart = filePart.getContentDisposition();
InputStream fileInputStream = filePart.getValueAs(InputStream.class);
String filePath = SERVER_UPLOAD_LOCATION_FOLDER + headerOfFilePart.getFileName();
// save the file to the server
saveFile(fileInputStream, filePath);
String output = "File saved to server location using FormDataMultiPart : " + filePath;
System.out.println(output);
return Response.status(200).entity(output).build();
}
}
My client:

Any idea?
I found a not good solution for now.
#POST
#Path("/upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(#FormDataParam("file") InputStream file, #FormDataParam("file") FormDataContentDisposition fileDetail, #QueryParam("fileName") String fileName){
...
...
String uploadedFileLocation = SERVER_UPLOAD_LOCATION_FOLDER+ fileName;//fileDetail.getFileName();
// save it
saveFile(file, uploadedFileLocation);
...
//Logic of the service.
...
//Delete file from local.
}
private void saveFile(InputStream uploadedInputStream, String serverLocation) throws IOException {
OutputStream outpuStream=null;
try {
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){
LOGGER.debug("[UploadWs - saveFile] - error: "+e);
} finally{
if(outpuStream!=null){
outpuStream.close();
}
}
}
"fileDetail" is always null and I don´t know why (if anyone knows the solution, say it) so I add the parameter "fileName" (name of the file) that the client send me. I build the location, I save the file in local, the logic of the service is executed (in my case, I send an email with this file) and I delete the file from local.
It's not a good solution because I add an unnecesarry parameter and I save the file in local.

I'm trying to implement a drag and drop feature for uploading files to my server.
Before mentioning my problem here is my code:
Front-End:
<div class="dndu">
<img class="dN_d" src="../logos/draganddrop.png" style="height:120px"/>
<span class="danddT">Drag & Drop</span>
<div class="dndbu"></div>
<div class="uppbd">
<label class="uppbb">
<input size="1" accept="image/*" class="BAPPB_B" value="Browse" type="file" style="position:fixed; top:-1000px;">
<span>Browse</span>
</label>
</div>
</div>
function upload(file){
xhr=new XMLHttpRequest();
xhr.open('post','../servlet',true);
xhr.setRequestHeader('Content-Type', 'multipart/form-data');
xhr.setRequestHeader('X-File-Name',file.fileName);
xhr.setRequestHeader('x-File-Size',file.fileSize);
xhr.setRequestHeader('X-File-Type',file.fileType);
xhr.send(file);
}
Back-End:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
for(Part p : request.getParts() ) {
InputStream filecontent = null;
OutputStream output = null;
output = new FileOutputStream(new File("C:/folder/bkimg.jpg"));
filecontent = p.getInputStream();
final byte[] bytes = new byte[1024];
int read = 0;
while((read = filecontent.read(bytes))!=-1){
output.write(bytes,0,read);
}
output.close();
}
}
The problem is that I am getting an exception in my server which says:

This question already has answers here:
What is a NullPointerException, and how do I fix it?
(12 answers)
Closed 6 years ago.
Working on a Spring MVC based project, I am getting the following code while I try to save review (Bean). I am able to get the data into controller successfully but for some reason getting a NULL pointer exception while saving.
Here is the code
-- JSP--
<div class="col-md-12">
<div class="p-b">
<cf:form action="${pageContext.request.contextPath}/reviews/add" id="reviewAction" modelAttribute="review" method="post" accept-charset="utf-8">

</div>
<label>Your Comment / Review</label>
<cf:textarea path="reviewMessage" name="reviewMessage" required="required"/>
<p class="text-right"><input type="submit" class="btn btn-default btn-sm" name="submit" value="Post"> </p>
</cf:form>
</div>
</div>
<cf:hidden path="userId" id="userId"/>
<script type="text/javascript">
$(document).ready(function () {
console.log("Calling getTutorId()");
getTutorId();
});
function getTutorId()
{
$('#tutorId').attr('value',$('#userId').val());
}
</script>
-- Controller --
#RequestMapping (value = "/add" , method = RequestMethod.POST)
public String addReview(#Valid #ModelAttribute Review review , BindingResult bindingResult, Model model) {
try {
if (bindingResult.hasErrors()) {
System.out.println(bindingResult.getAllErrors().iterator().next().toString());
return "FindTutor";
}
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
Date date = new Date();
String newDate = dateFormat.format(date); //06/08/2016 15:59:48
review.setDate(newDate);
review.setReviewStatus("Disapproved");
//Just for testing purposes
System.out.println(review.getStudentId());
System.out.println(review.getTutorId());
System.out.println(review.getDate());
System.out.println(review.getReviewMessage());
System.out.println(review.getReviewStatus());
//Just for testing purposes
reviewBL.saveReview(review);
List<Subject> subjectList = subjectBL.getAllSubjects();
List<User> userList = manageUserBL.getAllUsers();
model.addAttribute("subjectList", subjectList);
model.addAttribute("userList", userList);
} catch (Exception e) {
e.printStackTrace();
}
return "FindTutor";
}
-- Business Logic Class --
#Service
public class ReviewBL {
private ReviewsMongoRepository reviewsMongoRepository;
public void saveReview(Review review)
{
if (StringUtils.isEmpty(review.getId())) {
review.setId(null);
}
reviewsMongoRepository.save(review);
}
}
-- Bean Class --
#Document (collection = "reviews")
public class Review {
#Id
private String Id;
private String tutorId;
private String studentId;
private String date;

// plus constructors also all of the getters and setters
}
I am getting the following error message, and as you can see the data (Model Attribute is successfully been captured in the controller but is not being saved in the database due to a NULL pointer exception error that I can't seem to find out why

I was able to resolve this issue. It was because I didn't apply #Autowired on reviewsMongoRepository so it wasn't linked with the review bean. I corrected this and now it is working. Thank you
Inside ReviewBL.saveReview you are calling reviewsMongoRepository.save(review)
But I can see you havent initialized reviewsMongoRepository, this is just a reference type reffering to "nothhing." It might be the cause of your Null Pointer exception
I have reading some questions over this tags, but I can't solve my problem
I have a RESTful Web Service using Jersey 1.X version (1.19 according to Maven repository) in which I try to read a JSON Object from an Android application. The problem is due to when I send a JSON whose fields has any character like:
á
é
í
ö...
I want to repeat I am able to read a JSON without these specials characters. I try adding charset=UTF-8 and setting headers but it doesn't work.
Apache console give this log
com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException

I have a mess with this. Its driving me crazy.
I hope you can help me. Thanks!
Java Controller class:
#RequestMapping(value = "/upload" , method = RequestMethod.POST , consumes="multipart/form-data")
public void upload(#RequestParam MultipartFile file1) {
System.out.println("*****"+ file1);
}
html file:
<input id="file-0a" class="file" type="file" file-model="myFile"/>
<button ng-click="uploadFile()">upload me</button>
angular js:
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' + JSON.stringify(file));
var fd = new FormData();
fd.append('file', file);
var resource = /upload;
$http.post(resource, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
}).success(function(){ }).error(function(){ });
}
And this is the error I dont understand in the server log:

Try the following. It is working fine for me.
HTML You should have
<input id="file-0a" class="file" type="file" file-model="myFile" name="myFile" />
<button ng-click="uploadFile()">upload me</button>
Note the name of the input.
Then in JS controller method you should have
$scope.uploadFile = function(){
var formData=new FormData();
formData.append("file",myFile.files[0]); //myFile.files[0] will take the file and append in formData since the name is myFile.
$http({
method: 'POST',
url: '/upload', // The URL to Post.
headers: {'Content-Type': undefined}, // Set the Content-Type to undefined always.
data: formData,
transformRequest: function(data, headersGetterFunction) {
return data;
}
}).success(function(data, status) {
})
.error(function(data, status) {
});
}
Now in Your Java Controller class
#RequestMapping(value = "/upload" , method = RequestMethod.POST)
public void upload(HttpServletRequest request) {
//org.springframework.web.multipart.MultipartHttpServletRequest
MultipartHttpServletRequest mRequest;
mRequest = (MultipartHttpServletRequest) request;
Iterator<String> itr = mRequest.getFileNames();
while (itr.hasNext()) {
//org.springframework.web.multipart.MultipartFile
MultipartFile mFile = mRequest.getFile(itr.next());
String fileName = mFile.getOriginalFilename();
System.out.println("*****"+ fileName);
//To copy the file to a specific location in machine.
File file = new File('path/to/new/location');
FileCopyUtils.copy(mFile.getBytes(), file); //This will copy the file to the specific location.
}
}
Hope this works for You. And do Exception Handling also.
I am using this code to upload a file
#Path(value= "/up")
public class upload {
private String SERVER_UPLOAD_LOCATION_FOLDER= "C://Users/Marya/Desktop/" ;
#POST
#Path(value="upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public String uploadFile(
#FormDataParam("file") InputStream fileInputStream , #FormDataParam("name") String name ) {String filePath = SERVER_UPLOAD_LOCATION_FOLDER + name ;
System.out.println("*****serverpath********");
saveFile(fileInputStream, filePath);
String output = "File saved to server location : " + filePath;
System.out.println("done");
return output;}
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);
System.out.println("*****read********");
}
outpuStream.flush();
outpuStream.close();
} catch (IOException e) {e.printStackTrace();}
It seems that I have a problem with multipart.jar because when I use mutipart-1.18.jar the file is uploaded but it is empty!! When I changed to multipart-1.8.jar I get this output
File saved to server location : C://Users/Marya/Desktop/------ WebKitFormBoundaryxR9egGKFn3cgmnSz
Content-Disposition: form-data; name="name"
name
------WebKitFormBoundaryxR9egGKFn3cgmnSz
Content-Disposition: form-data; name="sms.PNG"; filename="sms.PNG"
Content-Type: image/png
And this error !!!

Can anyone help me to solve this issue plz !!
Are you sure that C://Users/Marya/Desktop is a valid path on your computer?
It looks like a Windows path but Windows uses backslashes as the path separator.
Try using backslashes instead. You may need to escape them.

Here is a good resource about constructing file paths in Java
