![]() Configure web.xml for Spring (Core, Web Flow, and Security). ![]() There isn't a perfect delineation between the Spring Web MVC, Web Flow and Security configurations, but they are mostly separated into their own separate files, with each requiring some entries in the web.xml. Building the Tutorial WARįollow the general instructions for building any of the tutorials. Configuration of the WebflowListener is shown in the webflow-config.xml configuration section below. You can download a copy of this WebflowListener directly from the link above, and it is also contained and configured in the tutorial. The spring-booking-tutorial uses the .WebflowListener (which is an instance of FlowExecutionListenerAdapter) class to this end. There is a solution, and that is to use a WebflowListener to duplicate the missing PhaseListener functionality. While the booking tutorial does not take advantage of windowScope, it is clear that functionality is reduced. Request map cleared prematurely.2) NPE trying to rewrite a null viewID into the document:Īt .DOMUtils.isWhitespaceText(DOMUtils.java:394)Īt .DOMUtils.printNode(DOMUtils.java:351)Īt .DOMUtils.printNode(DOMUtils.java:355) Side effects of this problem are the following symptoms:ġ) Console messages of the following form: Spring webflow applications, by default, use a POST->Redirect->GET pattern for navigation, but during the subsequent GET operation, the Spring lifecycle implementation does not appear to be executing the phase listeners during the RESTORE_VIEW phase. The ICEfaces BridgeSetup class uses a JSF PhaseListener to restore certain scope variables into the request map. There is an issue with the Spring implementation of the Lifecycle that affects the operation of ICEfaces. This tutorial borrows heavily from the Spring Web Flow sample booking application. Authenticated users can also review their bookings. Users can search for hotels and, after authenticating, book a room. The simple business case for this tutorial is the Spring Web Flow standard "booking application". Additional libraries are needed to support these frameworks and have been listed as dependencies in the tutorial's pom.xml file. This tutorial uses Spring Web Flow 2.5, Spring Security 5.1, Spring Core 5.1, JSF 2.2.16 and ICEfaces 3.3.0_P07. Understanding how the various parts of the web.xml file are organized to accomodate both frameworks is essential to understanding this tutorial and being able to extend it to meet your own requirements. Both technologies leverage the Servlet API. The purpose of this tutorial is to demonstrate how application developers can use both Spring Webflow 2.5 and ICEfaces 3.3.0 in the same application. ![]() This tutorial borrows heavily on existing JSF tutorials for Spring Web Flow, and is an evolution of the tutorial for integrating ICEfaces 3.x with Spring Web Flow 2.3.1. Go directly to the portion of this tutorial dealing with Spring Security 5.1 configuration. Authorization is applied at either the web resource level using Servlet Filters and/or at the business/service method level using aspects and annotations. Authentication is possible against any number of repositories and databases. Spring Security 5.1 provides an API for configuring authentication and authorization. Spring Web Flow is a library that extends Spring MVC to user defined "controllers using a domain-specific-language." Web Flow is appropriately used when several actions need to be performed in order for a greater action to be performed (booking a hotel, or a flight for instance). Spring Web Flow 2.5, Spring Security 5.1, and ICEfaces 3.3
