Re: WAR bundles and bundle activators

I have used a war bundle with Import-Package on org.osgi.framework, but have
never ran into any issues because of it. BTW, if you could post the
error/trace that you are getting when activating the WAR bundle, something
in our minds may click.
As Oleg points out the problem may be with getting the target platform

I have to admit I am a bit puzzled since I don't see any reason how
Import-Package: org.osgi.framework;version="1. 3.0" would affect the
workings of your WAR bundle.
Trying to replicate it here did not render any "negative results" :-)
. In fact, I was able to access BundleContext by changing one of my

Upon a closer look, I see that those warnings probably aren't my real
problem. Nonetheless, when org.osgi.framework is imported into the WAR
bundle, the application fails to deploy. Actually, it deploys...sort
of...but I get 404 errors when I try to hit any of the application's
pages.

The app in question is a traditional webapp that is being transitioned

These errors are reported correct, just check your servlet/jsp providing jar
if they contain the reported resources. Moreover its not fatal, its
warning., but better be armed with them.
So...any advice on how I can either (1) get an activator to work in a

Okay, I spoke too soon. I now restate my original question, this time
with new info.

After adding org.osgi.framework to Import-Package, my activator works
and my app *seems* to deploy. But in reality, it never gets off the
ground because of these errors:

Never mind...I figured out what was going on...

In my WAR project's pom.xml file (I'm using Maven2 to build), I had
included the OSGi API as a dependency, but (1) it was scoped as
"compile" resulting in it appearing in the WAR's WEB-INF/lib and (2) I
never added org.osgi.framework to Import-Package. Consequently, when

Re: WAR bundles and bundle activators

Following up on my first question...if I can't use a bundle activator
with my WAR bundle, then is there any way that I can get a reference
to the current Bundle and/or BundleContext from within the WAR bundle?

WAR bundles and bundle activators

I have a WAR bundle that Spring-DM's web extender is handling
beautifully. That is, until I added a rather simple bundle activator.
Once I added the Bundle-Activator: to the manifest, not only did my
activator not get called, but the web extender did not deploy my WAR.

My question: Is this expected behavior? I suppose that I could live

Hi,

thank you Thomas and Alex and Oleg.
Your sample works Oleg, great. I am surprised about the Manifest.MF a
little bit because I thought it must be more Spring DM specific. I am
happy that it works.

Great...after 10 days a solution..that is the part I don't love in the
profession of a software engineer. But the feeling if it runs is

Right Oleg. Even I felt the same. This is what I meant by my earlier posts
to Gaston. Getting the target platform right solves much of our problem.
Once we have this right, development starts to be faster.

I've updated tutorial with Chapter 6 (JSF application), so you can
read up and download working sample.

It is actually not difficult or tricky at all (at least for the simple
scenario). When I get time I'll try to extend it and make it more
complex (although I am not a JSF guru :-))
