Class AbstractMprServlet

  • All Implemented Interfaces:
    com.vaadin.server.Constants, Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
    public abstract class AbstractMprServlet
extends com.vaadin.server.VaadinServlet
    Base legacy VaadinServlet that creates a MprServletService.

    This servlet needs to be initialized before handling any Flow requests, so VaadinServlet.getCurrent() and VaadinService.getCurrent() can work when called from Flow.
