Hi all,
this is my first posting to this list. I am currently researching potential
solutions to the creation of an extensible Java application and OSGi/Felix
appear to provide one solution, with various future proofing capabilities
(for my currently simplistic requirements). So, I'm new to the world of OSGi
& Felix.
I'm finding the going quite tough learning about these technologies, due to
the sheer volume of information, but I have finally managed to locate, build
and run a sample application which seems to do almost everything I need
(http://felix.apache.org/site/apache-felix-application-demonstration.html).
The only additional feature I would like is the ability to configure the
embedded Felix framework to auto-install and auto-start (what Felix seems to
refer to as auto-deploy) all bundle JARs found in a specified bundle folder.
Felix documentation suggests that this is done by default, using the
"./bundle" sub-directory of the current directory, but this doesn't seem to
work for me, so I suspect the scenario is a little different with an
embedded Felix framework.
Can anyone point in the right direction for how to instruct Felix (when
embedded into an application) to auto-deploy all JARs found in a specified
folder?
There isn't too much difference between launching the framework and
embedding a framework instance into an existing application. In both
cases you are creating an instance an interacting with it externally to
get it to do something internally.
By default, the Felix framework doesn't do anything with any bundles
when you create an instance of it. It just sits there and waits for you
to tell it to do something. The example application you refer to above
(although it is a little outdated, since it doesn't use the most recent
Felix framework) provides one example. If you want to see another
example, just look at the source code for Felix Main, which is the
standard Felix framework launcher. It is quite simple and does the
auto-deploy functionality you describe. You can use this as a starting
point.
Regarding other examples, there is an updated example of the "paint"
program in the OSGi In Action book, the source code is available here:
http://code.google.com/p/osgi-in-action/
Look in the chapter 13 source directory.

Thanks in advance.
