2. Set the name of the activator class to „ch.hasselba.vaadin.Activator<\/em>“<\/p>\n 3. Open the MANIFEST.MF<\/em> file<\/p>\n 4. On Tab „Overview<\/em>„, activate the option for lazy loading and the singleton property<\/p>\n 5. Go to „Dependencies<\/em>“ tab and add the required plugin „com.ibm.pvc.webcontainer<\/em>“<\/p>\n When entering „pvc<\/em>„, you can easily find the plugin from the list:<\/p>\n 6. Then, add\u00a0 „javax.servlet<\/em>“ and „javax.servlet.http<\/em>“ to the list of imported packages<\/p>\n 7. Now, download the Jar files for Vaadin. The files can be found here<\/a> (the All-in-One<\/em> archive is the right one).<\/p>\n 8. Import the Jars to the project<\/p>\n The required Jars are:<\/p>\n 9. Do this with \u201ejsoup<\/a>\u201c and \u201eorg.json<\/a>\u201c libaries too:<\/p>\n 10. Now, go to the „Runtime<\/em>“ tab and add the classpathes (don’t forget to move the „.“ to the top of the list)<\/p>\n The symbol of the filetypes have now changed:<\/p>\n 11. On tab „Overview<\/em>„, click on „Extensions<\/em>“ to open the Extension tab<\/p>\n Click on „Yes<\/em>“ to open the „Extension<\/em>“ tab:<\/p>\n 12. Here, you have to add the extension point „com.ibm.pvc.webcontainer.application<\/em>“<\/p>\n 13. Open „plugin.xml“<\/em>…<\/p>\n 14. … and configure the extension point:<\/p>\n contextRoot<\/em> defines the URL pattern where the Vaadin servlet is reachable.\u00a0 contentLocation<\/em> is a folder where the required web.xml<\/em> configuration file can be found.<\/p>\n Save the „plugin.xml“ <\/em>file.<\/p>\n 15. Create the folder „WebContent<\/em>„…<\/p>\n 16. … and then a second folder „WEB-INF<\/em>“ inside of „WebContent<\/em>“<\/p>\n 17. Create the „web.xml<\/em>“ file in this folder, the tree should look like this:<\/p>\n 18. The „web.xml<\/em>“ contains the configuration of the servlet:<\/p>\n The <init-param><\/em> tag inside <servlet><\/em> defines our UI class of our application. We will create this class later. The <servlet-mapping><\/em> defines a mapping inside<\/em> the webapplication path.<\/p>\n This means, if you would add a url-pattern like „\/helloVaadinServlet\/*<\/em>“ to the Vaadin servlet, the URL to reach the application is<\/p>\n The „\/helloVaadin\/<\/em>“ part is the defined in the contextPath<\/em> parameter in the web application. When using another pattern as „\/*<\/em>„, an additional mapping for the Vaadin resources is required:<\/p>\n 19. Go to „Build<\/em>“ tab, and include the „Web-Content<\/em>“ folder:<\/p>\n The following line should now appear in the build.properties<\/em> file which includes the folder in the final Jar.<\/p>\n 20. Create the Vaadin servlet class „ch.hasselba.vaadin.HelloVaadinUI“<\/em><\/p>\n 21. Add the following code to the class<\/p>\n 22. At the end, organize the manifest. Open tab „Overview<\/em>“ and start the „Organize Manifest Wizard<\/em>“<\/p>\n This updates the manifest and adds all resources for the Vaadin application.<\/p>\n Last but not least, save all project files.<\/p>\n 25. Create a Feature Project named „HelloVaadinFeature<\/em>“ and click on „Next<\/em>“<\/p>\n 27. Select the „HelloVaadin<\/em>“ Plug-In<\/p>\n 28. On the „Plugins<\/em>“ tab, check the option „Unpack the plug-in archive after the installation<\/em>„:<\/p>\n Save the file and…<\/p>\n 29. … create the Update Site „HelloVaadinUpdateSite<\/em>“<\/p>\n Add the feature…<\/p>\n … and build the site:<\/p>\n 30. Import it to the Update Site on the Domino server and restart the HTTP task<\/p>\n 31. That’s it! Open the URL in the browser and enjoy.<\/p>\n This example requires a valid XPages Plugin Development Environment. The execution environment used is the XPages Domino JRE. 1. Create a new plug-in project and select „Equinox“ as OSGi framework 2.
