Hello
I was doing some experimentations with OSGi services, more precisely
what happens with bad construction of services. For example i have the
following bundles:
* JLService (only contains the interface JL):
o public interface JL {public boolean read(); }
* JL1, implementation of JLService that returns false on read method
* JL2, implementation of JLService that returns true on read
* JF, a bundle that consumes the JLService and gives a shell command
to invoke JL.read()
I am implementing the registering/discovery of services the worse
possible way.
On JL1 and JL2 start():
ref =
context.registerService(pt.thesis.JL.service.JL.class.getName(), new
JL1(), null); /*in JL2 is JL2()*/
On JL1 and JL2 stop():
ref.unregister();
On JF start():
refs = context.getServiceReference(JL.class.getName());
serv1 = (JL) context.getService(refs);
On JF stop():
context.ungetService(refs);
i start the bundles and JF is binded to JL1. if i stop JL1 and call the
command to invoke JL.read() why don't i get a runtime exception or
something?
Hope i explained my problem well
Thanks in advance
João Ferreira
