Dear Mr. Clement,
I really want to know so bad, why you told the person in this post:
http://apache-felix.18485.x6.nabble.com/Using-iPOJO-API-to-create-components-and-instances-td4881802.html
that his code should work if he used the following way:
new PrimitiveComponentType()
.setBundleContext(localContext)
.setClassName(ProviderA.class.getName())
.setValidateMethod("start")
.setInvalidateMethod("stop")
.addService(new Service())
.createInstance("TestProviderA");
But you told me not to use this way and to use DefaultInstanceDeclaration
instead.
This really confused me because I saw an answer for you in the same post with
the following code:
type = new
PrimitiveComponentType().setBundleContext(bundle.getBundleContext())
.setComponentTypeName("raw.type")
.setClassName("org.apache.felix.ipojo.test.asm.Raw")
.setImmediate(true);
type.start();
instance = type.createInstance();
What's different in my case? I can maybe switch to the other way if Declaration
Instance doesn't work. So, I need a clarification from you.
Zaid

Yes. This is the output:
ipojo:instances
Instance org.apache.felix.ipojo.arch.gogo.Arch-0 -> valid
