Access processAction in a portlet

General

Hi,

I am developing a portlet with vaadin. Now I have to use FileUpload (org.apache.commons).

My approach was to use a form in a label (simplified example):

public class VaadinasmtestApplication extends Application implements PortletListener{
	private String form = 	"<portlet:actionURL var=\"submitUrl\" />" +
							"<form method=\"post\" action=\"${submitUrl}\" enctype=\"multipart/form-data\">" +
							"<input type=\"file\" name=\"inputFile\" id=\"inputFile\">" +
							"<input type=\"submit\" name=\"Submit\" value=\"Upload\">" +
							"</form>";
	private Label upload = new Label(form, Label.CONTENT_RAW);
	
	@Override
	public void init() {
		if (getContext() instanceof PortletApplicationContext2) {
		      PortletApplicationContext2 ctx = (PortletApplicationContext2) getContext();
		      ctx.addPortletListener(this, this);
		}
		Window mainWindow = new Window("Vaadin-ASM-Test");
		setMainWindow(mainWindow);
		getMainWindow().addComponent(upload);
	}

	@Override
	public void handleRenderRequest(RenderRequest request,
			RenderResponse response, Window window) {
		System.out.println("calling handleRenderRequest...");
	}

	@Override
	public void handleActionRequest(ActionRequest request,
			ActionResponse response, Window window) {
		System.out.println("calling handleActionRequest...");
		//Code to handle the upload
	}

	@Override
	public void handleEventRequest(EventRequest request,
			EventResponse response, Window window) {
		System.out.println("calling handleEventRequest...");
	}

	@Override
	public void handleResourceRequest(ResourceRequest request,
			ResourceResponse response, Window window) {
		System.out.println("calling handleResourceRequest...");
	}
}

But the “handleActionRequest”-method is not called. I think I have to access the “processAction”-Method to get to the uploaded file.

Can someone help me?

Sincerely, Johannes
