struts: Bild als submit-button

[jean20]

Hallo,
ich möchte ein Bild als submit button nutzen. Nach dem Klicken soll das Programm in die execute-Methode der Action reinspringen.

<html:form action="/NavigationAction.do" method="post">
					<td width="60" height="43"><html:image
						src="img/buttons/start.PNG" property="start" onclick="/NavigationAction.do" />
					</td>
				</html:form>

In meiner NavigationForm habe ich das Attribut "start" mit den ensprechnden getter und setter.

Wieso bekomme ich diese Fehlermeldung?

Ich vermute mal, das Getter/Setter für "start" im ActionForm falsch sind. Ist der Objettype ein
ImageButtonBean? Ist der zugriff public? Wie sieht das Mapping in der StrutsConfig aus ?

Hallo,
versuch es doch mal so:

<html:image onclick="javascript:submit()" alt="Editieren"
						src="../static/img/find.jpg" />

Die Action ist ja schon in der Html:form angegeben. Sie muss nur noch Submittet werden.
Ciao velaluka
