GlassFish v3 a la carte screencast – Part 2

June 12, 2009 Comments Off

In the first screencast, I installed a minimal GlassFish v3 from a small bootstrap (IPS toolkit), created a domain and started the server. This entry will actually do something useful with GlassFish and two containers: Java Web and Spring.

The Spring DM (OSGi) part of the demo is described in Jerome’s GlassFish V3 Extensions, part 3 : Spring, Java EE 6 and OSGi blog entry. In the screencast, the manual install of the Spring bits is replaced by adding a new repository definition (a local one) and installing a single package from there. For the rest, the demo demonstrates how to extend GlassFish without using any GlassFish API and how to invoke an OSGi bundle service without using any OSGi API – the servlet injects the service by name using a standard @Resource annotation. Note that Jerome’s most recent blog entry covers OSGi Declarative Services for a somewhat simpler approach.

The screencast was done using the dev/ repository, so your experience may vary as the boundaries of the IPS packages and their dependencies are still being worked. Also, instead of the default Felix console briefly shown, you could use the web console described by Sahoo.

The next screencast will show how one can seamlessly add more GlassFish v3 features to obtain a “full” Java EE application server and still benefit from the modular architecture in terms of pay-as-you-grow (startup time, load-on-demand, memory consumption, …).
