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:
java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: the request was rejected because no multipart boundary was found at org.apache.catalina.connector.Request.parseParts(Request.java:2863) at org.apache.catalina.connector.Request.getParts(Request.java:2699) at org.apache.catalina.connector.RequestFacade.getParts(RequestFacade.java:1096) at duck.reg.pack.uploadtostack.doPost(servlet.java:25) at javax.servlet.http.HttpServlet.service(HttpServlet.java:648) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:230) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:165) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:192) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:165) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:199) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:108) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:522) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:140) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:620) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:87) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:349) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:1110) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:785) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1425) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.tomcat.util.http.fileupload.FileUploadException: the request was rejected because no multipart boundary was found at org.apache.tomcat.util.http.fileupload.FileUploadBase$FileItemIteratorImpl.(FileUploadBase.java:840) at org.apache.tomcat.util.http.fileupload.FileUploadBase.getItemIterator(FileUploadBase.java:256) at org.apache.tomcat.util.http.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:280) at org.apache.catalina.connector.Request.parseParts(Request.java:2791) ... 27 more

For starters, I wanted to make clear that I'm a newbie at programming, and for that I apologize in advance if this is something silly or if I can't express myself properly.
I'm developing a log in page that, when authenticated, redirects the user to another page. However, after that redirecting the page status is 500.
Browser status
My validation code:
#Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
RequestDispatcher dispatcher = getServletContext()
.getRequestDispatcher("/WEB-INF/config.jsp");
dispatcher.forward(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
HttpSession session = request.getSession(true);
if(username.equals("admin") && password.equals("admin")){
session.setAttribute("username", username);
doGet(request, response);
}
else {
response.sendRedirect("login.jsp");
}
};
My HTML:
<form method="post" action="Config">
<input type="text" id="username" name="username" placeholder="Usuário">
<input type="password" id="password" name="password" placeholder="Senha">
<input type="submit" value="Entrar">
</form>
And for ending the session:
session.invalidate();
response.sendRedirect("login.jsp");
*Edit:

I am trying to do oAuth2 DB authentication,
below is the code snippet which I am using having tokenUrl as
http://localhost:8025/oauth2db/oauth/token?grant_type=password&username=nithi5#gmail.com&password=nithi%
HttpClient httpClient = HttpClients.createDefault();
HttpPost httpPost = new HttpPost(tokenUrl);
try {
String auth = authConfiguration.getDatabaseClientId() + ":" + authConfiguration.getDatabaseClientSecret();
byte[] authEncrypted = Base64.encodeBase64(auth.getBytes(Charset.forName("ISO-8859-1")));
httpPost.setHeader("Authorization", "Basic " + new String(authEncrypted));
}
HttpResponse httpResponse = httpClient.execute(httpPost);
On doing this Im getting error as
"Malformed escape pair at index 103: http://localhost:8025/oauth2db/oauth/token?grant_type=password&username=nithi5#gmail.com&password=nithi%"
Below I am attaching complete log

URL query parameters must be URL-encoded so they don't contain special characters. For example & in a parameter value would be considered as a start of a new parameter. The % character is used to introduce an escape sequence (e.g. %20 is a space character), so it cannot be used alone and the parser complains about it:
Malformed escape pair
The solution is to URL encode all your parameter values. Probably the easiest way is to use Spring's own UriComponentsBuilder:
String url = UriComponentsBuilder
.fromHttpUrl('http://localhost:8025/oauth2db/oauth/token')
.queryParam('password', 'nithi%')
... // all other parameters here
.build()
.encode() // This will URL-encode the parameter values
.toUriString();
I have encoded the username and password before doing httpClient.execute(httpPost); and it works fine for me.
below is my code snippet:
public String getTokenURL(String username, String password) {
StringBuilder urlBuilder = new StringBuilder();
urlBuilder.append(authConfiguration.getDatabaseServiceUrl());
urlBuilder.append("/");
urlBuilder.append(authConfiguration.getDatabaseServiceContextPath());
urlBuilder.append("/oauth/token?grant_type=password&username=");
try {
urlBuilder.append(URLEncoder.encode(username,"UTF-8"));
urlBuilder.append("&password=");
urlBuilder.append(URLEncoder.encode(password,"UTF-8"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return urlBuilder.toString();
}

apiMessasge.setCode(-1);
}
}
return apiMessasge;
}
}
This is in Android
Uri resultUri = result.getUri();
File file = new File(resultUri.getPath());
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("file", file.getName(), requestFile);
And this is in APiService.class
#Multipart
#Headers("Content-Type:application/json")
#POST("/beongae/api/{version}/profile/upload/{name}")
Call<ApiMessasge> upload(#Path("version") int version, #Path("name") String fileName
, #Part MultipartBody.Part file);
And This is the error message in Spring Boot

But, It's done well when I use Postman.
Please tell me what is the problem and how to solve
Try to modify your service a little bit and try
#Part("file\"; filename=\"filename.png\" ")
Hi my first problem was that my application had to download a document (doc or pdf), searching on internet i found a solution and i adapted it to my code.
This is method in #Service where i retrieve blob from database
#Override
public boolean downloadCV(long idDocente, HttpServletResponse response) throws SQLException{
Connection con = null;
try{
con = DBCon.establishConnection();
String sql = "SELECT cv,content_type,filename FROM Docenti_pj where id_docente=? ";
PreparedStatement ps = con.prepareStatement(sql);
ps.setLong( 1 , idDocente);
ResultSet rs = ps.executeQuery();
while( rs.next() ) {
Blob blob = rs.getBlob("cv"); //prende il blob del curriculum
String contentType = rs.getString("content_Type");
String fileName = rs.getString("filename");
if(blob!=null){
InputStream inputStream = blob.getBinaryStream();
response.setHeader("Content-Disposition", "inline;filename=\"" +fileName+ "\"");
OutputStream out = response.getOutputStream();
response.setContentType(contentType);
IOUtils.copy(inputStream, out);
out.flush();
out.close();
return true;
}
else
return false;
}
}
catch(Exception e){
System.out.println("errore");
e.printStackTrace();
}
finally{con.close();}
return false;
}
This is method in my controller
#RequestMapping(value="/docente_cv")
public String downloadCurriculum(#RequestParam long idDocente, Model model, HttpServletResponse response){
try{
if(docenteService.downloadCV(idDocente,response))
return "redirect:/docente_profilo?IdDocente="+idDocente+"&cvdownload=true";
else
return "redirect:/docente_profilo?IdDocente="+idDocente+"&cvdownload=false";
}catch(Exception e){
String message = "Eccezione --> "+e.getMessage();
model.addAttribute("message", message);
return "redirect:/listaDocenteTot";
}
}
All is working fine, but i get in log this error everytime i download a document:

There is a better solution to work with document download in spring? I have saved in DB all file information.
Or there is a better way to use this code to avoid this exception?
Solved it!
I just needed to change code in "#Controller"'s class so i do redirect only if document is not found or exception catched.
As Deinum said you can't downalod and redirect
You may use this code:
#RequestMapping(method = { RequestMethod.GET }, value = { "/docente_cv" })
public ResponseEntity<InputStreamResource> downloadCsv(#PathVariable("idForm") String idForm)
{
Connection con = null;
String fileName = "";
try
{
con = DBCon.establishConnection();
String sql = "SELECT cv,content_type,filename FROM Docenti_pj where id_docente=? ";
PreparedStatement ps = con.prepareStatement(sql);
ps.setLong( 1 , idDocente);
ResultSet rs = ps.executeQuery();
while( rs.next() )
{
Blob blob = rs.getBlob("cv"); //prende il blob del curriculum
String contentType = rs.getString("content_Type");
fileName = rs.getString("filename");
if(blob!=null)
{
InputStream inputStream = blob.getBinaryStream();
response.setHeader("Content-Disposition", "inline;filename=\"" +fileName+ "\"");
HttpHeaders respHeaders = new HttpHeaders();
MediaType mediaType = MediaType.parseMediaType(contentType)
respHeaders.setContentType(mediaType);
respHeaders.setContentLength(file.length());
respHeaders.setContentDispositionFormData("attachment", fileName);
InputStreamResource isr = new InputStreamResource(inputStream);
return new ResponseEntity<InputStreamResource>(isr, respHeaders, HttpStatus.OK);
}
else
{
return new ResponseEntity<InputStreamResource>(HttpStatus.NO_CONTENT);
}
}
}
catch (Exception e)
{
String message = "Errore nel download del file "+fileName+"; "+e.getMessage();
logger.error(message, e);
return new ResponseEntity<InputStreamResource>(HttpStatus.INTERNAL_SERVER_ERROR);
}
finally
{
if(con != null)
con.close();
}
}
I hope it's useful

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.
