And my JSP code is :
<body>
<h1>Please upload a file</h1>
<form method="post" action="upload.action" enctype="multipart/form-data">
<input type="text" name="name"/></br>
<input type="file" name="file"/></br>
<input type="submit"/>
</form>
</body>
and my servlet-context.xml code is :
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- one of the properties available; the maximum file size in bytes -->
</bean>
<bean id="fileUploadController" class="com.mpm.common.controller.FileUploadController" ></bean>
You seem to use Spring. In that case, I usually manage multipart requests like this:
#RequestMapping("/url")
public String method(HttpServletRequest request) {
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
// do stuff with multipartRequest
return "/jsp";
}
You simply need to cast your HttpServletRequest request.
public void upload(HttpServletRequest request) {
File up = new File("C:\\temp"); // path where u need to upload
// Create object of MultipartRequest to upload file
MultipartRequest m;
try {
m = new MultipartRequest(request, up.toString());
Enumeration files = m.getFileNames();
// Get the files to be uploaded from enumeration
while (files.hasMoreElements()) {
String upload = (String) files.nextElement();
filename = m.getFilesystemName(upload);
// out.println("<br/><br/><br/><br/>");
}
} catch (IOException e) {
System.out.println("Error in Uploading files...");
}
xsdName = filename.substring(0, filename.lastIndexOf('.'));
}
it was my code to do the same in servlet. Hope it helps.

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.
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.
In the jsp i am passing the data as json,as in the controller method i am trying to map the data to Personbean object using #RequestMapping. But its throwing an exception.
#ResponseBody is working fine, if i remove the #ResponseBody code.
Please suggest what am i doing wrong?
I have pasted the code for reference.
//jsp (added the data as json and also content type)
<script>
function abc(){
alert('here!!');
$.ajax({
url:'anki',
type:'GET',
data:({name:"me"}),
dataType: 'json',
contentType: 'application/json',
success:function(data){
alert('here gain');
$('#time').html(data.name);
}
});
}
</script>
<input type="button" name="submit" title="submit" onclick="abc()"/>
<div id="time"></div>
//PersonBean (Bean class)
package com.controller;
public class Personbean {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
// controller method

Try this
$.ajax({
url:'anki',
type:'POST',
data:JSON.stringify(eval({"name":"me"})),
dataType: 'json',
contentType: 'application/json',
success:function(data){
alert('here gain');
// $('#time').html(data.name);
}
});
Dont forget to change the Method to POST in your controller
method=RequestMethod.POST
The GET method will not work because it will send the data in the URL and not in the request body.
#RequestBody expects data to be present in body of request. Changing the http method to POST will resolve the error.
I'm trying to upload pdf files in the server. And i;m using the following block of code into the controller:
#RequestMapping(value = /submit, method = RequestMethod.POST)
public String upload(UploadItem uploadItem, BindingResult result, HttpServletRequest request, HttpSession session) {
//some code here
String name = request.getServletContext().getRealPath("/pdf/" + filename);
File dest = new File(name);
try {
file.transferTo(dest);
}catch(Exception e){
System.err.println(e);
}
return "redirect:/details";
I'm doing this in order to store the pdf's into the pdf file. In my localhost works fine but when i'm executing this on the server i'm taking the following exception:
exception

If i remove the lines that provide above in the controller class is working(ofcource without uploading the pdf's). Can anyone help me with this?
That method request.getServletContext() was introduced in servlet 3.0. Make sure your container/library support that version.
edit: tomcat 6 only have servlet 2.5, see http://tomcat.apache.org/whichversion.html
it can be autowired: ServletContext and Spring MVC
public class Xxxx{
#Autowired
ServletContext context;
#RequestMapping(value = "/submit", method = RequestMethod.POST)
public String upload(UploadItem uploadItem, BindingResult result, HttpServletRequest request, HttpSession session) {
//some code here
String name = context.getRealPath("/pdf/" + filename);

Trying to use Ajax, Spring, REST and JAXB but getting Errors....... I am trying to do a REST call from Ajax to Spring. I am getting the following errors..
Here is my JSP:

here is the code that is in my controller:
#RequestMapping(method=RequestMethod.PUT, value="/employee")
public ModelAndView updateEmployee(#RequestBody String body) {
System.out.println("in put");
Source source = new StreamSource(new StringReader(body));
Employee e = (Employee) jaxb2Mashaller.unmarshal(source);
System.out.println(e.toString());
return new ModelAndView(XML_VIEW_NAME, "object", e);
}
and now for the error....

It looks like you're sending the object in json format and trying to unmarshal it with jaxb (xml). It obviously gives you an exception.
If you have jackson in the classpath, the unmarshalling from JSON should be automatic. You only need to have a parameter #RequestBody Employee employee instead of #RequestBody String body
this might help..
