Quick inheritence question

Hello all,

Would the following be considered bad practice...

I have a very simple bean called "SimpleTypeBean" which is constructed
as follows:

public class SimpleTypeBean {

  private long id;
  private String description;

  public SimpleTypeBean() {
  }

  public long getId() {
    return id;
  }

  public void setId(long id) {
    this.id = id;
  }

  public String getDescription() {
    return description;
  }

  public void setDescription(String description) {
    this.description = description;
  }
}

I then need to declare a very similar bean (in fact, it is identical
in terms of data types), except one of the identifiers is called lob
not id, so I have done the following:

public class LobBean extends SimpleTypeBean {

  public LobBean() {
  }

  public long getLob() {
    return super.getId();
  }

  public void setLob(long lob) {
    super.setId(lob);
  }

}

Is this considered bad practice or is this what I should be doing?

Many Thanks

Andy
