Hello,
I’m struggling with running my vaadin-Application on an IBM WebSphere AS. I can deploy it, but once I’m trying t start it, the start fails with this Exception:
com.ibm.ws.exception.RuntimeWarning: com.ibm.ws.exception.RuntimeWarning: com.ibm.ws.webcontainer.exception.WebAppNotLoadedException: Failed to load webapp: Failed to load webapp: null

My Project is pretty simple:
I have a WebProject, that contains all vaadin-jars and a MainView.java file, which is just:
@Route("")
public class MainView extends VerticalLayout
{
public MainView()
{
Button button = new Button("TEST");
button.addClickListener(e -> {
Notification.show("test");
});
this.add(button);
}
}
so nothing too fancy. This WebProject is surrounded by an EAR-Project, that contains nothing else (tested with an application.xml, but no difference.)
One should note, that this very same Project exported as the same .ear runs just perfectly on an empty wildfly server - but no matter what I’m trying: I do not get vaadin to run on WebSphere (followed the available Tutorials already).
Any help / Idea is highly appreciated!
Simon
