Hi, Amindri. The JmxModuleActivator should receive the injected ExtensionPointRegistry from Tuscany runtime instead of instantiating its own instance. To do so, you need to create a constructor of JmxModuleActivator that takes the ExtensionPointRegistry argument and uses it for the start/stop methods.
For example, public class JmxModuleActivator implements ModuleActivator { private ExtensionPointRegistry registry; public JmxModuleActivator(ExtensionPointRegistry registry) { this.registry = registry; ... } public void start() { // Do something with registry } ... } Thanks, Raymond ________________________________________________________________ Raymond Feng rf...@apache.org Apache Tuscany PMC member and committer: tuscany.apache.org Co-author of Tuscany SCA In Action book: www.tuscanyinaction.com Personal Web Site: www.enjoyjava.com ________________________________________________________________ On Jul 11, 2011, at 6:35 PM, Amindri Udugala wrote: > > > On 10 July 2011 15:09, Luciano Resende <luckbr1...@gmail.com> wrote: > On Sat, Jul 9, 2011 at 9:53 PM, Amindri Udugala > <amindriudug...@gmail.com> wrote: > > Hi, > > > > > > After going through the Tuscany code carefully I decided that the best way > > to access runtime artifacts like Endpoints, Components, Composites and > > Services was to access the DomainRegistryFactoryExtension > > Point.
