save image file in specific directory jsf primefaces project - file-upload

Question

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
}
}
