About this Presentation

OSGi defines a module system and service platform for the Java language. GlassFish is the Java EE 6 Reference Implementation and uses an OSGi kernel to create a light-weight and modular Application Server. There is a lot of activity in the Enterprise Expert Group of OSGi about use of OSGi in enterprise Java environment. GlassFish is a container for standard Java EE applications and also supports what is called a “hybrid application”. A hybrid application is a Java EE application as well as an OSGi bundle. It allows application components such as Servlets, EJBs to take full advantage of:

  • Features such as modularity/dependency management, service dynamism, etc. provided by OSGi service platform.
  • Services such as transaction management, security, persistence, etc. offered by the Java EE platform.

This presentation will provide:

  • A short introduction to OSGi
  • Explain how OSGi is used in GlassFish to provide a modular and light-weight App server
  • Different ways to manage the OSGi runtime in GlassFish
  • Change the default Felix runtime in GlassFish to Equinox or Knopflerfish
  • Create a simple OSGi application using CLI and IDEs and deploy in GlassFish
  • Create a OSGi + Java EE hybrid application and show/discuss the benefits of such an application
