Frank van der Linden / elstar IT Since a few years the Domino server is a real Java server. Which give you plenty of new opportunities, such as real servlets. Get and post data to any database via a Java servlet. Develop once, run everywhere. In this session you will learn what are servlets, how to create a servlet as OSGi plugin. Make use of other plugins projects or third party projects and. Run the servlet on a Domino server and other Java servers, like Websphere Liberty Profile, Tomcat and Wildfly. Last but not least, how to deploy the servlet as OSGi plugin or as jar file or update site to the Domino server.

5. What is a servlet
• Java program to extends the capabilities of a server
• Servlets provide a component-based, platform-independent method
for building Web-based applications
• Servlets run in web containers, Servlet containers

9. Servlet in NSF
• excellent series of Eric McCormick
• https://edm00se.io/servlet-series/

10. Servlet as OSGi plugin
• run server wide
• Code can be shared with other processes like DOTS, XPages.
• With small changes, it run also on other Java servers, like Tomcat,
WildFly(a.k.a. Boss) and Websphere

12. Prepare

13. Prepare
• Download IDE e.g. Eclipse JEE
• Set Target platform
• Install PDE Debug plugin
• Create com.ibm.notes.java.api project
13
*See Appendix A for steps to prepare your IDE

14. Develop

15. goals
• Create a Shared code plugin
• Create a web app plugin which runs on a Java server
• Create a OSGi servlet which run on a Domino server
15
* See Appendix B for setup projects

27. Test
• tell http quit
• load http

28. Warning
• After testing remove the pre.launch.ini from your workspace
directory of the Domino server

29. Deploy

30. Deploy
• 2 ways of deployment to Domino
• as deployable jar
• as an update site.
• Add to web server
30

31. As deployable jar
• Export as deployable plugin…
• Put the jar in the correct directory on the server
• tell http quit —> load http
31

32. As update site
• Create Feature project, add plugin projects
• Create Update site project, add Feature project
• Add update site to update site database
• tell http quit —> load http
