Currently, enterprise Java development is being revolutionized by the use of OSGi. The ability to dynamically add, remove, and replace functionality at runtime is allowing applications to behave as never before. However, the one application class untouched by OSGi is arguably the class with the most to gain from it. In this session, SpringSource dm Server core developer Ben Hale will discuss the his Slices project. Slices uses OSGi technologies to build completely modular and dynamic web applications. Demonstrations will range from the simple runtime addition of application functionality to the inclusion of dynamically created framing content from other components.
