I'm stuck on file upload (allways not accpting uploading) - file-upload

I'm stuck ... I followed several tutorial but I do not know what's my problem ... I need to uplod files in the Repertoir C: \ PDF
but I do not get to do
this is my
<h:form enctype="multipart/form-data">
<p:fileUpload
mode="advanced"
fileUploadListener="#{composantbean.upload}"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/" sizeLimit="100000" description="Select Images"
auto="true"/>
</h:form>
this is my methode on bean
#ManagedBean(name="composantbean")
#SessionScoped
public class Composantbeam {
private String destination="C:\\PDF\\";
public void upload(FileUploadEvent event) {
FacesMessage msg = new FacesMessage("Success! ", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
// Do what you want with the file
try {
copyFile(event.getFile().getFileName(), event.getFile().getInputstream());
} catch (IOException e) {
e.printStackTrace();
}
}
public void copyFile(String fileName, InputStream in) {
try {
// write the inputStream to a FileOutputStream
OutputStream out = new FileOutputStream(new File(destination + fileName));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = in.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
in.close();
out.flush();
out.close();
System.out.println("New file created!");
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
}
this is my error message it allaws shown when a upload a file
C:\PDF\C:\Documents and Settings\Admin\Bureau\login.png (Syntaxe du nom de fichier, de répertoire ou de volume incorrecte)
C: \ PDF \ C: \ Documents and Settings \ Admin \ Desktop \ login.png (syntax file name, directory or incorrect volume)

The problem is that event.getFile().getFileName() is returning filename with complete path
so I change My methode Like this
File result = new File(destination+ ***FilenameUtils.getName***(event.getFile().getFileName()));
Commons IO offers FilenameUtils#getName() for the exact purpose.
think you all :)

Dropbox Java Api Upload File

How do I upload a file public and get link ? I am using Dropbox Java core api. Here.
public static void Yukle(File file) throws DbxException, IOException {
FileInputStream fileInputStream = new FileInputStream(file);
InputStream inputStream = fileInputStream;
try (InputStream in = new FileInputStream(file)) {
UploadBuilder metadata = clientV2.files().uploadBuilder("/"+file.getName());
metadata.withMode(WriteMode.OVERWRITE);
metadata.withClientModified(new Date());
metadata.withAutorename(false);
metadata.uploadAndFinish(in);
System.out.println(clientV2.files());
}
}
I use the following code to upload files to DropBox:
public DropboxAPI.Entry uploadFile(final String fullPath, final InputStream is, final long length, final boolean replaceFile) {
final DropboxAPI.Entry[] rev = new DropboxAPI.Entry[1];
rev[0] = null;
Thread t = new Thread(new Runnable() {
public void run() {
try {
if (replaceFile == true) {
try {
mDBApi.delete(fullPath);
} catch (Exception e) {
e.printStackTrace();
}
//! ReplaceFile is always true
rev[0] = mDBApi.putFile(fullPath, is, length, null, true, null);
} else {
rev[0] = mDBApi.putFile(fullPath, is, length, null, null);
}
} catch (DropboxException e) {
e.printStackTrace();
}
}
});
t.start();
try {
t.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
return rev[0];
}

Adding new revision for document in DropBox through android api

I want to add a new revision to the document(Test.doc) in Dropbox using android api. Can anyone share me any sample code or links. I tried
FileInputStream inputStream = null;
try {
DropboxInputStream temp = mDBApi.getFileStream("/Test.doc", null);
String revision = temp.getFileInfo().getMetadata().rev;
Log.d("REVISION : ",revision);
File file = new File("/sdcard0/renamed.doc");
inputStream = new FileInputStream(file);
Entry newEntry = mDBApi.putFile("/Test.doc", inputStream, file.length(), revision, new ProgressListener() {
#Override
public void onProgress(long arg0, long arg1) {
Log.d("","Uploading.. "+arg0+", Total : "+arg1);
}
});
} catch (Exception e) {
System.out.println("Something went wrong: " + e);
} finally {
if (inputStream != null) {
try {
inputStream.close();
} catch (IOException e) {}
}
}
New revision is created for first time. When i execute again, another new revision is not getting created.

save image file in specific directory jsf primefaces project

I want to save byte[] file into a specific directory :
I get it from this method :
public void setUploadedPicture(UploadedFile uploadedPicture)
{
System.out.println("set : "+uploadedPicture.getFileName()+" size : "+uploadedPicture.getSize());
this.uploadedPicture = uploadedPicture;
}
and I access the byte[] with :
uploadedPicture.getContents()
I tested this link but no result
how to save it into a specific directory either inside my project or outside
thank you
*********EDIT**********
here is the code whic works but sometimes I have the error :
public void setUploadedPicture(UploadedFile uploadedPicture)
{
System.out.println("set : "+uploadedPicture.getFileName()+" size : "+uploadedPicture.getSize());
this.uploadedPicture = uploadedPicture;
InputStream inputStr = null;
try {
inputStr = uploadedPicture.getInputstream();
} catch (IOException e) {
e.printStackTrace();
}
//create destination File
String destPath = "C:\\"+uploadedPicture.getFileName();
File destFile = new File(destPath);
//use org.apache.commons.io.FileUtils to copy the File
try {
FileUtils.copyInputStreamToFile(inputStr, destFile);
} catch (IOException e) {
e.printStackTrace();
}
}
public void handleFileUpload(FileUploadEvent event) {
//get uploaded file from the event
UploadedFile uploadedFile = (UploadedFile)event.getFile();
//create an InputStream from the uploaded file
InputStream inputStr = null;
try {
inputStr = uploadedFile.getInputstream();
} catch (IOException e) {
//log error
}
//create destination File
String destPath = "your path here";
File destFile = new File(destPath);
//use org.apache.commons.io.FileUtils to copy the File
try {
FileUtils.copyInputStreamToFile(inputStr, destFile);
} catch (IOException e) {
//log error
}
