Example Stripes Action Bean

NewGameActionBean

@UrlBinding("/experimental/new/game")
public class NewGameActionBean extends BaseActionBean implements ActionBean {

	private final static String JSP_NEWGAME = "/jsp/experimental/new_game.jsp";
	private Game game = null;

	@DefaultHandler
	public Resolution defaultHandler() {
		return new ForwardResolution(JSP_NEWGAME);
	}

	public Resolution update() {
		if (this.game!=null) {
			this.setDebugString(game.toWebString());
		}
		return new ForwardResolution(JSP_NEWGAME);
	}

	public Game getGame() {
		return game;
	}

	@ValidateNestedProperties({
		@Validate(field="mainTitle", required=true, on="update")
	})
	public void setGame(Game game) {
		this.game = game;
	}
}

line 1:

@UrlBinding("/experimental/new/game")

Very simple way to determine the URL under which the site will be available.

line 7:

@DefaultHandler

This Method is called when the URL is visited. Returns a Resolution to the JSP-File new_game.jsp.

line 12:

public Resolution update() {

This method is called when the HTML-Form-Submit-Button (see below in new_game.jsp) is clicked (<stripes:submit name="update">).

The methods getGame and setGame srepresent the Bean property "game", which can be accessed (read and write) from the corresponding jsp file.

line 24:

@Validate(field="mainTitle", required=true, on="update")

The form field "game.mainTitle" is validated (must not be empty) in the methode "update".
