The ISA-Skillnet folks have set up a rare local opportunity for people to get some insights into the world of OSGi on Thursday this week (9th September) at the IBEC offices on Lower Baggot St. The inimitable Ian Bull, the lead for the Eclipse Zest visualization toolkit and an Equinox p2 committer will be doing the pitch. Ian knows his onions when it comes to this material and if you are looking for a solid explanation of why OSGi exists, what it does and how you can use it to structure your Java development and enforce runtime component isolation, you should get your carcass over to this talk, which is free to anyone who works for an Software Skillnet member company - list of members here (PDF link). You could get your company to join up, or just email them an ask about individual access.
Here’s the announcement: http://www.isa-skillnet.com/Training_Courses/88#ss162. The show starts at 1745.
