60 XPages vs. Vaadin History and Presence XPages Vaadin Bought by IBM in 2001 (XForms) Was Workplace Based on JSF Development by IBM (Core, closed source) and partly by the community (ExtLib) In 2001 newly developed as Millstone Library (IT Mill) Uses GWT since 2007 (IT Mill Toolkit 4) Feels like SWT/AWT/Swing Further development by Vaadin Ltd. (open source, Apache licensed) 60

61 XPages vs. Vaadin Operating systems XPages Vaadin All Domino supportes operating systems All operating systems with Java 6 and higher 61

62 XPages vs. Vaadin Supported AppServers XPages Vaadin IBM Domino XPages Buildpack (IBM Bluemix) Apache Tomcat 5+ IBM WebSphere (Full/Liberty) 7+ JBoss 4+ Liferay Portal 5.2 Oracle WebLogic WildFly 8+ Java Servlet 2.4 / JSR

63 XPages vs. Vaadin Release / Dependencies XPages Vaadin Rely on Domino-Updates (Major, Minor, FP, IF) Updating the App-Server means Updating all XPages applications A server update affects all XPages applications New release (minor) all 4-5 weeks Updates of the AppUpdates are independent from Vaadin and vice versa Vaadin-Updates can be done selectively on a per-applicatio base 63
