com.sun.enterprise.admin.server.core.jmx.SunoneInterceptor

A class that is a poor man's interceptor. There are following reasons that led to use this interceptor and not the standard JMX 1.2 interceptor.

Tight deadlines and smoke test has to work :(

We have lazy loading going on. (Again poor man's) This means that any MBean has to be registered first before it can be invoked. We did not have any good solution at the architectural level for that, nor does JMX 1.2 have it. The way we do it is to check that persistent medium and/or Java Beans derived from the dtd and initialized from domain.xml (in memory) indicate that such an element should exist, and then we register the mbean before invoking it. This solves the problem of initialization meaning the MBeans for all the elements in configuration file (domain.xml) do not have to be registered in order to invoke the operation.

Still, we want a JMX 1.2 implementation of the MBeanServer as some immediate future work may need it.

Ugliness to begin with gives birth to more ugliness. This class has to handle the case of config files being hand edited. :(((

Hence this interceptor results. All it does is the following:

Implements the javax.management.MBeanServer as sincerely as possible.

Uses Lazy loading meaning that the MBeans will be registered if they do not already exist in registry of the MBeanServer. An attempt will be made to see that config bean already exists. (This is not a violation per se, but an interpretation of the MBeanServer specification). @see javax.management.MBeanServer @since 8.0


        final DynamicInterceptor dyn = (DynamicInterceptor)getMBeanServer();
        final MBeanServer delegateMBeanServer = dyn.getDelegateMBeanServer();
        adminContext.setMBeanServer( dyn );
        
        final SunoneInterceptor sunone =
            SunoneInterceptor.createInstance(adminContext, dyn, delegateMBeanServer);
        dyn.addHook( COM_SUN_APPSERV, sunone );
        FeatureAvailability.getInstance().registerFeature(
            FeatureAvailability.SUN_ONE_INTERCEPTOR_FEATURE, "true");
        AMXLoggingHook.enableLoggingHook();
        sunone.registerConfigMBeans();
            
        if (sLogger.isLoggable(Level.FINE)) {
            sLogger.log(Level.FINE, "core.sunone_interceptor_enabled");
        }
        initCallFlow();
