Jacorb Publish a Corba Servant on well know port without Naming Service

Thanks to the posts from - [jacorb-developer] 'Publish a Servant on well know port'

I was able to do the same. Below are the server and client snippet. This is using Jacorb ORB.

Server code

String[] args3=  { "-DOAPort=4013" };

        java.util.Properties argProps = ObjectUtil.argsToProps( args3 );
               
        Properties props = System.getProperties();

        props.put("org.omg.CORBA.ORBClass", "org.jacorb.orb.ORB");//JACORB
        props.put("org.omg.CORBA.ORBSingletonClass", "org.jacorb.orb.ORBSingleton");
        props.put("org.omg.PortableInterceptor.ORBInitializerClass.bidir_init",
          "org.jacorb.orb.giop.BiDirConnectionInitializer");
        props.put("jacorb.implname","StandardImplName");
        props.putAll( argProps );
        System.setProperties(props);

orb = org.omg.CORBA.ORB.init(args, props);

root_poa = org.omg.PortableServer.POAHelper.narrow( orb.resolve_initial_references("RootPOA")); Any any = orb.create_any(); BidirectionalPolicyValueHelper.insert( any, BOTH.value );

org.omg.CORBA.Policy [] policies = new org.omg.CORBA.Policy[4]; policies[0] =Server.root_poa.create_id_assignment_policy(IdAssignmentPolicyValue.USER_ID); policies[1] =Server.root_poa.create_lifespan_policy(LifespanPolicyValue.PERSISTENT); policies[2] = root_poa.create_implicit_activation_policy( ImplicitActivationPolicyValue.NO_IMPLICIT_ACTIVATION ); policies[3] = orb.create_policy( BIDIRECTIONAL_POLICY_TYPE.value,any );

poa = root_poa.create_POA("NeDetailsPOA",root_poa.the_POAManager(),policies);

//Activate POA manager 
poa.the_POAManager().activate();

//Now register this with the ORB //
org.omg.CORBA.Object obj = poa.servant_to_reference(nedetials);
poa.activate_object_with_id("NeDetails".getBytes(), nedetials);
orb.run();

Client code

Usual Orb routine stuff & then

String location2 = "corbaloc:iiop:127.0.0.1:4013/StandardImplName/NeDetailsPOA/NeDetails"; org.omg.CORBA.Object obj = orb.string_to_object(location2); nedetails = NeDetailsHelper.narrow(obj); proto.inmc.fm.CorbaServer.NE_DETAILS details2 = nedetails.GetNEDetails(1);

Long running Java process resource consumption monitoring , leak detection and GC tuning

For easily monitoring the JVM metrics there is no better tool than Java VisualVM or its older counterpart JConsole; These two tools comes with the Java JDK. So it is absolutely necessary that you copy a JDK version to some temp directory in which your server runs. {Make sure that you do not install the JDK / put the java executable in the path.} Before going in JVM monitoring, it is essential to understand a little about Java's memory model. Note - This article is written with  HotSpot JVM in mind,which is one of the most commonly used one ; implemented by OpenJDK and Oracle - formerly from Sun. This is not the only one , notable being JRockit and others ; and some details would change with a different JVM. When you are running a Java Process in a Server you allocate the Memory for the Java Virtual Machine. This memory is split to process heap { what you give withe the Xmx Xms command}where it is again subdivided on generational basis (Young, Old)  and the PermGen -...

JavaScript (Prototypal) Inheritance with new and Object.create

//--------------------------- //Inheritance in JavaScript //--------------------------- var Person = function (string){ this.name= string; //if ( !(this instanceof Person) ) //part soln to danger 1 // return new Person(name); }; Person.prototype.get_name = function(){ return this.name; }; //Danger 1 : No compile errors here if new is skipped //Also inside the function would now be the global this object, //not the new instance! The constructor would be overriding all sorts //of global variables inadvertently var manu = Person("Manu"); name; manu.get_name(); //Danger 1 :only run time error here;Crackford's reason var adi = new Person("Adi"); adi.get_name(); //Okay let us try Iheritance with new var Employee = function (name,company){ this.name = name; this.company=company; Person.call(this,name); }; Employee.prototype.get_company = function(){ return this.comany; }; //How to inherit from Person ? //Step 1 - Link the prototypes /...
