-jar file is archive file that contain application or library class
-bean is an java class that have variables and access methods for Java Bean it needs to implement Serializable interface, here is an example

public class FirstBean implements Serializable {
  private int id;
  private String name;

  public FirstBean(int id, String name) {
    this.id = id;
    this.name = name;

  public void setId(int id) {
    this.id = id;
  public int getId() {
    return this.id;

  public void setName(String name) {
    this.name = name;

  public String getName() {
    return this.name;

it is an action that deployers do when they want to install they application on server.
it is noun of deploy :)
