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
