ABSTRACTS:

1. OSGi CDI Integration Specification (Speaker: Raymond Augé)

The OSGi Alliance has developed a specification describing integration between OSGi and CDI. The combination of these two powerful development technologies opens the door to new possibilities. This talk will walk through the most essential features of the specification and show some code and running examples.

2) Building OSGi Projects with Bnd in Maven (Speaker: Raymond Augé)

The Bndtools.org team has spent a number of years focused on improving support for OSGi development in Maven. This talk will demonstrate the latest innovations demonstrating features such as quick setup, minimal configuration, use of bundle annotations, BOM support, testing and running.

3) Promises in Java: Using Promises to recover from failures (Speaker: BJ Hargrave)

Communications is error prone. Connections time out, servers fail to respond, returned data can be incomplete or corrupted. Bnd, the OSGi tooling project, has an HttpClient class which is used for communications including with remote repositories like Maven/Nexus and P2 repositories. The Bnd CI builds started having significant failures due to communications problems with the Eclipse download servers, so with some light code restructuring, I was able to add retry support to HttpClient using the Promises package from OSGi.

This session will take a look at the Promises package and how it was easily used to recover from communications failures.
