Felix embedded in JBoss
Hi,
I am working on embedding felix into jboss. I want to be able to use
services from OSGI bundles in my java ee container, and also use
service from my java ee container in my OSGI bundles.
Right now I am trying to setup a simple HelloService that should get
called from an EJB.
The embedded felix instance is created using a servletcontextlistener.
The service interface for the HelloService is deployed in my ear and
also added to the Felix FRAMEWORK_SYSTEMPACKAGES.
Below is the initialization code :
Map configMap = new StringMap(false);
// Configure the Felix instance to be embedded.
configMap.put(FelixConstants.EMBEDDED_EXECUTION_PROP, "true");
configMap.put(FelixConstants.SERVICE_URLHANDLERS_PROP,
"false");
// Add the host provided service interface package and the
core OSGi
// packages to be exported from the class path via the system
bundle.
configMap.put(Constants.FRAMEWORK_SYSTEMPACKAGES,
"org.osgi.framework; version=1.3.0,"
+ "org.osgi.service.packageadmin; version=1.2.0," +
"org.osgi.service.startlevel; version=1.0.0,"
+ "org.osgi.service.url; version=1.0.0,
org.osgi.util.tracker; version=1.3.1, "
+ "foo.bar.osgi.service.helloworld; version=1.0.0,");
configMap.put(AutoActivator.AUTO_START_PROP + ".1",
"file:bundle/foo-bar-osgi-helloworld-impl-1.1-
SNAPSHOT.jar");
// Explicitly specify the directory to use for caching bundles.
configMap.put(BundleCache.CACHE_PROFILE_DIR_PROP, "cache");
// Create activator,
OSGIFelixActivator osgiFelixActivator = new
OSGIFelixActivator();
List<BundleActivator> baseBundles = new
ArrayList<BundleActivator>();
baseBundles.add(osgiFelixActivator);
// Bind activator
try {
EjbUtils.bindComponent(OSGIFelixActivator.JNDI_PATH,
osgiFelixActivator);
} catch (NamingException e1) {
LOG.error("[TODO]", e1);
}
// Now create an instance of the framework.
Felix felix = new Felix(configMap, baseBundles);
// Now start Felix instance.
try {
LOG.debug("Starting Felix OSGI container");
felix.start();
} catch (BundleException e) {
LOG.error("[TODO]", e);
}
The OSGIFelixActivator is an activator that stores the BundleContext,
and registeres a ServiceTracker on the HelloService.
This activator is then bound to JNDI to later on use it in my EJB.
My problems are that when felix is initialized, I am getting an
IOException during initialization of the felix ExtensionManager.

And secondly the OSGI bundle implementing the HelloService never gets

Has anyone had more success ? I saw a post using the same approach on

Hi Wim,
Any chance I can reach you somehow by email?
I am working on the same problem as you were.
Thanks

I am using 1.0.4.
The problem was indeed forgetting to add the AutoActivator.
Regarding the exception, I tried both enabling and disabling the URL
Handlers and both gave the same error.
I looked a bit deeper in the code as to what is happening and it can
be safely ignored, its just a debug message, the url is added to the
jboss classloader afterwards.
regards,
Wim.

Re: Felix embedded in JBoss
Posted by Karl Pauls <ka...@gmail.com>.
What version of felix are you using?
Furthermore, you need to add a special activator to the felix
constructor (via the same list you already use to add yours) to make
the autostart property work. Have a look at:
http://svn.apache.org/repos/asf/felix/trunk/main/src/main/java/org/apache/felix/main/Main.java
to see how it is done (the activator is
org.apache.felix.main.AutoActivator). Otherwise your bundle will not
be started.
Alternatively, you could do something like the following:
Felix felix = new Felix(configMap, new ArrayList());
felix.start();
felix.getBundleContext().installBundle("file:bundle/foo-bar-osgi-helloworld-impl-1.1-SNAPSHOT.jar").start();
In regard to the exception you see, try to enable/disable URLHandlers
(your code looks like you disable it but then the stacktrace doesn't
look like you do) and see whether that makes it go away. If not, you
can just ignore it (it shouldn't matter).
regards,
Karl
