Summary: Using iPOJO API shows different behavior (Only works when
adding a service)
Key: FELIX-4443
URL: https://issues.apache.org/jira/browse/FELIX-4443
Project: Felix
Issue Type: Bug
Components: iPOJO
Affects Versions: ipojo-runtime-1.11.1
Environment: Windows 64 Operating System, eclipse, java
Reporter: Zaid
I am trying to use ipojo API to create a component type. I am embedding Felix
framework and I load my component bundle to the framework.
In my bundle I have the following class:
public class PlainHelloImpl implements PlainHello{
@Override
public void sayHello() {
System.out.println("Plainly Hello :D");
}
public PlainHelloImpl()
{
System.out.println("in contructor");
}
public void start()
{
System.out.println("Hello, this is the plain hello component
start method");
}
public void stop()
{
System.out.println("Bye, this is the plain hello component stop
method");
}
}
and below is my activator where the error occurs:
public class Activator implements BundleActivator {
public static BundleContext bundleContext;
public void start(BundleContext context) throws Exception {
System.out.println("Plain Hello iPOJO Bundle Started!");
bundleContext=context;
PrimitiveComponentType x= new PrimitiveComponentType()
.setBundleContext(context)
.setClassName(PlainHelloImpl.class.getName())
.setValidateMethod("start")
.setInvalidateMethod("stop")
.addService(new Service()) ;
x.start();
ComponentInstance i = x.createInstance(); //ERROR HERE
i.start();
System.out.println("and we are done!");
}
public void stop(BundleContext context) throws Exception {
context = null;
System.out.println("Plain Hello iPOJO Bundle Stopped!");
}
}
In my java application, I have the following code:
Map config= new HashMap();
// Create a configuration property map.
//Map config = new HashMap();
config.put(Constants.FRAMEWORK_STORAGE_CLEAN,
Constants.FRAMEWORK_STORAGE_CLEAN_ONFIRSTINIT);
// Create host activator;
m_activator = new HostActivator();
List list = new ArrayList();
list.add(m_activator);
config.put(FelixConstants.SYSTEMBUNDLE_ACTIVATORS_PROP, list);
try
{
// Now create an instance of the framework with
// our configuration properties.
m_felix = new Felix(config);
// Now start Felix instance.
m_felix.start();
}
catch (Exception ex)
{
System.err.println("Could not create framework: " + ex);
ex.printStackTrace();
}
// Register the application's context as an OSGi service!
BundleContext bundleContext1 = m_felix.getBundleContext();
//starting ipojo required bundles
Bundle coreBundle =
bundleContext1.installBundle("file:C:\\Users\\zaid.almahmoud\\Dropbox\\EBTIC\\ADERE\\feasibility-codes\\ipojo\\ipojo-distribution-1.11.0\\bundle\\org.apache.felix.ipojo-1.11.0.jar");
coreBundle.start();
if(coreBundle.getState()== Bundle.ACTIVE)
System.out.println("Core Bundle is Active!");
Bundle compositeBundle =
bundleContext1.installBundle("file:C:\\Users\\zaid.almahmoud\\Dropbox\\EBTIC\\ADERE\\feasibility-codes\\ipojo\\ipojo-distribution-1.11.0\\bundle\\org.apache.felix.ipojo.composite-1.6.0.jar");
compositeBundle.start();
if(compositeBundle.getState()== Bundle.ACTIVE)
System.out.println("Composite Bundle is Active!");
Bundle apiBundle =
bundleContext1.installBundle("file:C:\\Users\\zaid.almahmoud\\Dropbox\\EBTIC\\ADERE\\feasibility-codes\\ipojo\\ipojo-distribution-1.11.0\\bundle\\org.apache.felix.ipojo.api-1.6.0.jar");
apiBundle.start();
if(apiBundle.getState()== Bundle.ACTIVE)
System.out.println("API Bundle is Active!");

Fragment Bundle supplying a Require-Capability seems to not work
Just a heads-up, According to the specs, it should be possible for a Fragment to add a Require-Capability to a Host. I tried this with Log4J to have it wait for an Apache FileInstall exploded bundle to supply the Capability, but it didn't seem to take. If I get the time, I'll try to gather the work and submit a case. If anyone is familiar with the code, I'd appreciate a quick pointer to the responsible class. I'd like to submit a patch along with the case. Thanks, Nick Baker
Re: Fragment Bundle supplying a Require-Capability seems to not work
Hello Nick, From your description I cannot determine if you first installed, resolved and started the host and then installed the fragment or if the fragment was already installed at the point where the host resolved. I’m asking because that’s a common pitfall when dealing with fragments: if you install them after the host has already been resolved, “nothing happens”.
