Admin console problem

[romain.vdk]

Hi,
I've a little problem with the Pro admin console : when I try to open it, I get a blank page.
Here is the code used to open it :

adminDsButton.addClickHandler(new ClickHandler() {
	@Override
	public void onClick(ClickEvent event) {
		SCPRO.openDataSourceConsole();
	}
});

The admin console URL is the following : http://127.0.0.1:8888/com.alea.Alea/tools/adminConsole.jsp

The error trace is the following:
00:03:28,123 [INFO] 200 - GET /com.alea.Alea/tools/adminConsole.jsp (127.0.0.1)
00:03:43,074 [INFO] 200 - GET /com.alea.Alea/sc/skins/Enterprise/images/pickers/comboBoxPicker_Over.png (127.0.0.1) 428 bytes

Any idea of what could be wrong? I followed the steps described in the Quick Start guide
