In a complex enterprise application you will have some classes which
are not serializable or even translatable to Javascript. If you want
to serialize a bean which has a field with this class the compilation
will fail. For example, let's suppose that you have this bean:
@Entity
public class User {
................
private Calendar loginDate;
.................
}
@Entity
public class Document {
private String title;
@ManyToOne
@GwtTransient
private User author;
public void setAuthor(User author);
public User getAuthor();
}
Now, you want to use the Document bean in your GWT application. It
only has a dependency on the non serializable class User as a relation
and you are completely sure that you will not call any getter or
setter of the field it in your code. You can:
- Include Document in the client package and leave User outside. Even
if the source code of User is available in the same jar, the
compilation will fail complaining that User.class does not have source
code.
- Include both classes in the client package. The compilation will
fail because User is not translatable to Javascript due to the use of
Calendar.
So this annotation is only useful to leave already simple classes
outside of the serialization, but it's not useful if you want to
ignore a type which is too complex for GWT to handle.
