Answer 1

Try following code:

xhtml:

jsf:

@ManagedBean
@ViewScoped
public class ImageUpload_2 implements Serializable {

UploadedFile uploaded_image;

public UploadedFile getUploaded_image() {
    return uploaded_image;
}

public void setUploaded_image(UploadedFile uploaded_image) {
    this.uploaded_image = uploaded_image;
}
String upload_location;

public String getUpload_location() {
    return upload_location;
}

public void setUpload_location(String upload_location) {
    this.upload_location = upload_location;
}

public void handleFileUpload(FileUploadEvent event) {
    uploaded_image = event.getFile();
    ServletContext servletContext = (ServletContext) FacesContext.getCurrentInstance().getExternalContext().getContext();
    String v_file_ext = uploaded_image.getFileName().split("\\.")[(uploaded_image.getFileName().split("\\.").length) - 1];
    upload_location = servletContext.getRealPath("") + File.separator + "temp-images" + File.separator + "3" + "." + v_file_ext;
    FileImageOutputStream imageOutput;
    try {
        imageOutput = new FileImageOutputStream(new File(upload_location));
        imageOutput.write(uploaded_image.getContents(), 0, uploaded_image.getContents().length);
        imageOutput.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

public void btn_save_clicked(ActionEvent event) {

    byte[] file = new byte[uploaded_image.getContents().length];
    System.arraycopy(uploaded_image.getContents(), 0, file, 0, uploaded_image.getContents().length);
    //ent.setImg(file);
    //yourfacade.create(ent);
}

public ImageUpload_2() {
}
}

Where ent is the object of Entity Class and img (setImg) is database column of BLOB type.You just need to create "temp-images" folder in you project under web folder where xhtml files are lying. Tell me if you are still having any issue.
