UndeclaredThrowableException with a client only eclipse scout application

I am trying to do a client only Eclipse Scout application.

I selected the menu “New Scout Project…” and in the first step of the wizard I checked only:

com.company.app.ui.swt
com.company.app.client
com.company.app.shared

Everything seems to be fine, but when I start my client application, I get following Stacktrace:

!ENTRY org.eclipse.scout.rt.client 4 0 2014-07-09 15:35:06.078

Why does the Client application needs to connect to a server that do not exists?

Solution

This is an issue of the Scout SDK.

When you create your new scout project, the generated client code rely on a server, even if you have unchecked the server in the wizard.

You need to remove the elements that produce calls to the server.

In <your app>.client.ClientSession.execLoadSession() remove the lines:

setServiceTunnel(new ClientHttpServiceTunnel(this, UriUtility.toUrl(getBundle().getBundleContext().getProperty("server.url"))));

//pre-load all known code types
CODES.getAllCodeTypes(com.company.app.shared.Activator.PLUGIN_ID);

In <your app>.client.ui.desktop.Desktop remove the inner-class:

@Order(25)
public class BookmarkMenu extends AbstractBookmarkMenu {
  public BookmarkMenu() {
    super(Desktop.this);
  }
}

Your client only application will start.
