The managed bean is:
import javax.faces.context.FacesContext;
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.UploadedFile;
@Component
@ManagedBean
@SessionScoped
public class FileUploadController {
public void handleFileUpload(FileUploadEvent event) {
FacesMessage msg = new FacesMessage(“Succesful”, event.getFile().getFileName() + ” is uploaded.”);
FacesContext.getCurrentInstance().addMessage(null, msg);
//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
e.printStackTrace();
}
//create destination File
String destPath = “D:\fbm\user\”+event.getFile().getFileName();
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
e.printStackTrace();
}
}
}
