I have to upload a file from my site yet cnt seem to get it working with drop wizard.
Here is the form from my site.
<form enctype="multipart/form-data" method="POST" action="UploadFile">
<input type="file" id="fileUpload" name="file"/>
<input type="hidden" id="fileName" name="fileName"/>
<input type="submit" value="Upload"/>
</form>
How would I go about on the backend to receive the file?
The solution was
@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
@FormDataParam("file") final InputStream fileInputStream,
@FormDataParam("file") final FormDataContentDisposition contentDispositionHeader) {
String filePath = uploadLocation + newFileName;
saveFile(fileInputStream, filePath);
String output = "File can be downloaded from the following location : " + filePath;
return Response.status(200).entity(output).build();
}
private void saveFile(InputStream uploadedInputStream,
String serverLocation) {
try {
OutputStream outputStream = new FileOutputStream(new File(serverLocation));
int read = 0;
byte[] bytes = new byte[1024];
outputStream = new FileOutputStream(new File(serverLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, read);
}
outputStream.flush();
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
You could do the saving to the server in lesser number of lines using nio
java.nio.file.Path outputPath = FileSystems.getDefault().getPath(<upload-folder-on-server>, fileName);
Files.copy(fileInputStream, outputPath);
Also, if you're using 0.7.0-rc2, you will need this dependency in your pom.xml
<dependency>
<groupId>com.sun.jersey.contribs</groupId>

<version>1.18</version>
