Hope you all will be fine. I want to upload file in a database, i.e, user select file from the computer and when it click on the save button then the file should save in a database.
I am trying Primefaces file upload but although the message is that file has been uploaded but file not showing in a directory. Here is my code. Please tell me why the file is not showing in a directory.
Code: Select all
ManagedBean
@RequestScoped
public class UploadBean {
private static final int BUFFER_SIZE = 6124345;
/** Creates a new instance of UploadBean */
public UploadBean() {
} //end of constructor
public void handleFileUpload(FileUploadEvent event) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
File result = new File(externalContext.getRealPath("//WEB-INF//upload") + "//" + event.getFile().getFileName() );
try {
FileOutputStream fileOutputStream = new FileOutputStream(result);
byte[] buffer = new byte[BUFFER_SIZE];
int bulk;
// Here you get uploaded picture bytes while debugging you can see that 34818
InputStream inputStream = event.getFile().getInputstream();
while(true) {
bulk = inputStream.read(buffer);
if (bulk < 0) {
break;
} //end of if
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
} //end fo while(true)
fileOutputStream.close();
inputStream.close();
FacesMessage msg = new FacesMessage("Succesful",event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
} catch (IOException e) {
e.printStackTrace();
FacesMessage error = new FacesMessage("The files were not uploaded!");
FacesContext.getCurrentInstance().addMessage(null, error);
}
} //end of handleFileUpload()
} // end of class UploadBean
