I am trying to set up file upload example using JAX RS. I could set up the project and successfully upload file in a server location. But i get the following error when file size is more than 10KB (weird!!)
com.sun.jersey.api.client.UniformInterfaceException: POST http://localhost:9090/DOAFileUploader/rest/file/upload returned a response status of 400
at com.sun.jersey.api.client.WebResource.handle(WebResource.java:607)
at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74)
at com.sun.jersey.api.client.WebResource$Builder.post(WebResource.java:507)
at com.sony.doa.rest.client.DOAClient.upload(DOAClient.java:75)
at com.sony.doa.rest.client.DOAMain.main(DOAMain.java:34)
I am new to JAX RS and i'm not sure what exactly the issue is. Do i need to set some parameters client side or server side (like size, timeout etc)?
This is the client side code calling webservice:
public void upload() {
File file = new File(inputFilePath);
FormDataMultiPart part = new FormDataMultiPart();
part.bodyPart(new FileDataBodyPart("file", file, MediaType.APPLICATION_OCTET_STREAM_TYPE));
WebResource resource = Client.create().resource(url);
String response = resource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);
System.out.println(response);
}
This is the server side code:
#Path("/file")
public class UploadFileService {
#POST
#Path("/upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
#FormDataParam("file") InputStream uploadedInputStream,
#FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "e://uploaded/"
+ fileDetail.getFileName();
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[16000];
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();
} } }
Please let me know what settings i have to change for file sizes greater than 10KB?
Thanks!
I use org.apache.commons.fileupload.servlet.ServletFileUpload in a Jersey context, and it works fine., and yes, it set the max file size, sorry I missed this before.
here is a snipet of code I use (this is a multipart form, so there are other fields along with the file)
private LibraryUpload parseLibraryUpload(HttpServletRequest request) {
LibraryUpload libraryUpload;
File libraryZip = null;
String name = null;
String version = null;
ServletFileUpload upload = new ServletFileUpload();
upload.setFileSizeMax(MAX_FILE_SIZE);
FileItemIterator iter;
try {
iter = upload.getItemIterator(request);
while (iter.hasNext()) {
....
if (item.isFormField()) {
....
}else{
BufferedInputStream buffer = new BufferedInputStream(stream);
buffer.mark(MAX_FILE_SIZE);
libraryZip = File.createTempFile("fromUpload", null);
IOUtils.copy(buffer, new FileOutputStream(libraryZip));
...
}
I have encountered the same problem with Jersey. I have activated jersey trace but nothing help me.
I have changed the library by an apache Library and I see than the problem with linked to a repository for temporary files for tomcat. The repository was not exist. For files under 10k, the repository was not used.
So, after the repository creation, I used jersey library and all works fine.

I'm trying to save pdf in wildfly, I'm using RestEasy MultipartFormDataInput provided with wildfly 20.0.1,
but it doesn't work.
This is what I have:
public static Response uploadPdfFile(MultipartFormDataInput multipartFormDataInput) {
// local variables
MultivaluedMap<String, String> multivaluedMap = null;
String fileName = null;
InputStream inputStream = null;
String uploadFilePath = null;
try {
Map<String, List<InputPart>> map = multipartFormDataInput.getFormDataMap();
List<InputPart> lstInputPart = map.get("poc");
for(InputPart inputPart : lstInputPart){
// get filename to be uploaded
multivaluedMap = inputPart.getHeaders();
fileName = getFileName(multivaluedMap);
if(null != fileName && !"".equalsIgnoreCase(fileName)){
try {
// write & upload file to UPLOAD_FILE_SERVER
//here I have the error: Unable to find a MessageBodyReader for media type:
//application/pdf
inputStream = inputPart.getBody(InputStream.class,InputStream.class);
uploadFilePath = writeToFileServer(inputStream, fileName);
}catch (Exception e) {
e.printStackTrace();
}
// close the stream
inputStream.close();
}
}
}
catch(IOException ioe){
ioe.printStackTrace();
}
finally{
// release resources, if any
}
return Response.ok("File uploaded successfully at " + uploadFilePath).build();
}
I'm using postman for test, http POST method, in the body I send: form-data - file and selected the file.pdf.
When I sent the request, I have the next RunTimeException when I try:
inputStream = inputPart.getBody(InputStream.class,null);
I get:
java.lang.RuntimeException: RESTEASY007545: Unable to find a MessageBodyReader for media type: application/pdf and class type org.jboss.resteasy.util.Base64$InputStream
At the moment I am saving the file receiving it in Base64, but I think that with MultipartFormDataInput it is the correct way.
This is what I have when debug:
Thanks for your support.
I solved this changing the InputStream from "org.jboss.resteasy.util.Base64.InputStream"
to "java.io.InputStream"
I use the code stated here to upload files through a webapi http://bartwullems.blogspot.pe/2013/03/web-api-file-upload-set-filename.html. I also made the following api to list all the files I have :
[HttpPost]
[Route("sharepoint/imageBrowser/listFiles")]
[SharePointContextFilter]
public async Task<HttpResponseMessage> Read()
{
string pathImages = HttpContext.Current.Server.MapPath("~/Content/images");
DirectoryInfo d = new DirectoryInfo(pathImages);//Assuming Test is your Folder
FileInfo[] Files = d.GetFiles(); //Getting Text files
List<object> lst = new List<object>();
foreach (FileInfo f in Files)
{
lst.Add(new
{
name = f.Name,
type = "f",
size = f.Length
});
}
return Request.CreateResponse(HttpStatusCode.OK, lst);
}
When calling this api, all the files uploaded are listed. But when I go to azure I dont see any of them (Content.png is a file I manually uploaded to azure)
Why are the files listed if they dont appear on azure.
According to your description, I suggest you could firstly use azure kudu console to locate the right folder in the azure web portal to see the image file.
Open kudu console:
In the kudu click the debug console and locate the site\wwwroot\yourfilefolder
If you find your file is still doesn't upload successfully, I guess there maybe something wrong with your upload codes. I suggest you could try below codes.
Notice: You need add image folder in the wwwort folder.
{
public class UploadingController : ApiController
{
public async Task<HttpResponseMessage> PostFile()
{
// Check if the request contains multipart/form-data.
if (!Request.Content.IsMimeMultipartContent())
{
throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
}
string root = Environment.GetEnvironmentVariable("HOME").ToString() + "\\site\\wwwroot\\images";
//string root = HttpContext.Current.Server.MapPath("~/images");
var provider = new FilenameMultipartFormDataStreamProvider(root);
try
{
StringBuilder sb = new StringBuilder(); // Holds the response body
// Read the form data and return an async task.
await Request.Content.ReadAsMultipartAsync(provider);
// This illustrates how to get the form data.
foreach (var key in provider.FormData.AllKeys)
{
foreach (var val in provider.FormData.GetValues(key))
{
sb.Append(string.Format("{0}: {1}\n", key, val));
}
}
// This illustrates how to get the file names for uploaded files.
foreach (var file in provider.FileData)
{
FileInfo fileInfo = new FileInfo(file.LocalFileName);
sb.Append(string.Format("Uploaded file: {0} ({1} bytes)\n", fileInfo.Name, fileInfo.Length));
}
return new HttpResponseMessage()
{
Content = new StringContent(sb.ToString())
};
}
catch (System.Exception e)
{
return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e);
}
}
}
public class FilenameMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
public FilenameMultipartFormDataStreamProvider(string path) : base(path)
{
}
public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
{
var name = !string.IsNullOrWhiteSpace(headers.ContentDisposition.FileName) ? headers.ContentDisposition.FileName : Guid.NewGuid().ToString();
return name.Replace("\"", string.Empty);
}
}
}
Result:
I am developing a plugin using org.sonarsource.sonarqube:sonar-plugin-api:6.3. I am trying to access a file in my resource folder. The reading works fine in unit testing, but when it is deployed as a jar into sonarqube, it couldn't locate the file.
For example, I have the file Something.txt in src/main/resources. Then, I have the following code
private static final String FILENAME = "Something.txt";
String template = FileUtils.readFile(FILENAME);
where FileUtils.readFile would look like
public String readFile(String filePath) {
try {
return readAsStream(filePath);
} catch (IOException ioException) {
LOGGER.error("Error reading file {}, {}", filePath, ioException.getMessage());
return null;
}
}
private String readAsStream(String filePath) throws IOException {
try (InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream(filePath)) {
if (inputStream == null) {
throw new IOException(filePath + " is not found");
} else {
return IOUtils.toString(inputStream, StandardCharsets.UTF_8);
}
}
}
This question is similar with reading a resource file from within a jar. I also have tried with /Something.txt and Something.txt, both does not work.If I put the file Something.txt in the classes folder in sonarqube installation folder, the code will work.
Try this:
File file = new File(getClass().getResource("/Something.txt").toURI());
BufferredReader reader = new BufferedReader(new FileReader(file));
String something = IOUtils.toString(reader);
Your should not use getContextClassLoader(). see Short answer: never use the context class loader!
I have the following code for saving image in mongodb:
public static void insertImage() throws Exception {
String newFileName = "mkyong-java-image";
File imageFile = new File("c:\\JavaWebHosting.png");
GridFS gfsPhoto = new GridFS(db, "photo");
GridFSInputFile gfsFile = gfsPhoto.createFile(imageFile);
gfsFile.setFilename(newFileName);
gfsFile.save();
}
And I got this from this link:
link for code
But when I use that I get the following error and I do not know how to fix it ... Can anyone help?
Exception in thread "main" java.lang.NullPointerException
at com.mongodb.gridfs.GridFS.<init>(GridFS.java:97)
for more explanation the error is at exactly this line:
GridFS gfsPhoto = new GridFS(db, "photo");
Update:
Here is the code for creating db connection
public static DB getDBConnection() {
// If it's not connected to the database, make connection
if (db == null) {
initialize();
makeConnections();
}
return db;
}
private static void makeConnections() {
MongoCredential credential = MongoCredential.createMongoCRCredential(dbUser, dbName, dbPass.toCharArray());
MongoClient mongoClient;
try {
mongoClient = new MongoClient(new ServerAddress(dbHost, Integer.parseInt(dbPort)), Arrays.asList(credential));
db = mongoClient.getDB(dbName);
} catch (UnknownHostException e) {
e.printStackTrace();
}
}
Update:
String newFileName = "mkyong-java-image";
File imageFile = new File("D:/1.jpg");
db = MongoDB.getDBConnection();
collection = db.getCollection("test");
// create a "photo" namespace
GridFS gfsPhoto = new GridFS(db, "photo");
// get image file from local drive
GridFSInputFile gfsFile = gfsPhoto.createFile(imageFile);
// set a new filename for identify purpose
gfsFile.setFilename(newFileName);
// save the image file into mongoDB
gfsFile.save();
// print the result
DBCursor cursor = gfsPhoto.getFileList();
while (cursor.hasNext()) {
System.out.println(cursor.next());
}
// get image file by it's filename
GridFSDBFile imageForOutput = gfsPhoto.findOne(newFileName);
// save it into a new image file
imageForOutput.writeTo("D:\\JavaWebHostingNew.jpg");
// remove the image file from mongoDB
// gfsPhoto.remove(gfsPhoto.findOne(newFileName));
System.out.println("Done");
I have a page containing links to some files.
I basically need to access the source of the page for parsing it then and obtaining all the hyperlinks to the files.
My code is something like this (some piece of code I've found in many places on the net ..):
"private static byte[] ReadImageFromUrl(string url)
{
var myReq = (HttpWebRequest)WebRequest.Create(url);
myReq.Timeout = 10000;
WebResponse myResp = myReq.GetResponse();
Stream stream = myResp.GetResponseStream();
List<byte> bytesList = new List<byte>();
using (var br = new BinaryReader(stream))
{
try
{
while (true)
{
var b = br.ReadByte();
bytesList.Add(b);
}
}
catch (Exception)
{}
br.Close();
}
myResp.Close();
return bytesList.ToArray();
}"
Now the problem is I get "System.Net.WebException: The remote server returned an error: (500) Internal Server Error." when calling "myReq.GetResponse()" - examining the error I see that the status is 'ProtocolError'.
The response property of the WebException object contains some server error ..(although when opening it from the browser it opens correctly) ...also when I call this function with the url of one of my files I get the same ProtocolError status, but the 404 error ...
Please give any hint how could I solve it... or any other possibility of accomplishing this task.
Thanks !
My new code after using Fiddler is:
private static byte[] ReadFileFromUrl(string url)
{
var myReq = (HttpWebRequest)WebRequest.Create(url);
myReq.Accept = const_AcceptHeader;
myReq.Headers.Set(const_AcceptLanguageHeaderName, const_AcceptLanguageHeader);
myReq.UserAgent = const_AcceptUserAgentHeader;
myReq.CookieContainer = new CookieContainer();
myReq.KeepAlive = true;
myReq.Timeout = Int32.Parse(ConfigSettings.RequestPageTimeout) * 1000;
WebResponse myResp = null;
List<byte> bytesList = null;
myResp = myReq.GetResponse();
Stream stream = myResp.GetResponseStream();
bytesList = new List<byte>();
using (var br = new BinaryReader(stream))
{
try
{
while (true)
{
var b = br.ReadByte();
bytesList.Add(b);
}
}
catch (Exception ex)
{
throw;
}
br.Close();
}
return bytesList.ToArray();
}
All variables that start with const_ are taken from Fiddler.
Well, I solved that using Fiddler ... I passed to my request object the headers as I have seen them in Fiddler ...& it worked, no error
