Pattern b/w Remote interface & Container implementation  class

Which pattern is followed by EJB Remote interface & Container implementation class of that interface?Is there anyting mentioned in specs?
This questoin was asked to me by many people.I think it is Command design pattern as it hides away all the details of actual business implementation.but at same time I doubt if it is Facade?
Anyone who knows about this?
Thanx in advance
Sidhu

Rarely is software represent a single pattern, it typically represents multiple patterns.
Which pattern is followed by EJB Remote interfaceThe remote interface is an example of a facade pattern. This presents a public interface which is an abstraction of the real interface.
Container implementation class of that interface? The implementation is an example of what I think of as a double proxy pattern. That is acting as two distinct proxies. The first being the the remote callingof EJB standard functions via the Skelton implementation. I.E. The underlying EJB/RMI interface. The Second being a application level proxying of the business logic seen in most RL implementation.
The use of an UID ID beans is an example of a memento.
I think it is Command design pattern as it hides away all the
details of actual business implementation.Not directly, though an AppServer programmer may use the Command Pattern to resolve the remote connections. The User Application Programmer may also use this pattern. The key element of Command Pattern is the Invoker executing an concrete class via abstraction or interface of a polymorphic class. You can think of this as a specialisation of the

  • ClassCastException at Remote object although remote interface is implemented

    Hi,
    I want to access a remote object via T3 (on WebLogic 10) but I am
    getting a ClassCastException in the client. The exception is thrown if
    the generic "Remote" object is casted into a concrete remote interface.
    The following works ok (client side, get remote object via JNDI):
    Hashtable hashTable = new Hashtable();
    hashTable.put(Context.INITIAL_CONTEXT_FACTORY,
    "weblogic.jndi.WLInitialContextFactory");
    hashTable.put(Context.PROVIDER_URL, "t3://localhost:7001);
    ic = new InitialContext(hashTable);
    Remote r = (Remote) ic.lookup("...jndi bind name...");
    But this cast fails:
    IMyRemoteIntf i = (IMintRemoteIntf) r;
    The ClassCastException has the classname of the class which implements
    the remote interface - the lookup should be ok therefore. With
    r.getClass().getInterfaces() I have verified that the remote object
    actually implements the appropriate interface. I suppose it is a class
    loader issue then and added some debug output.
    Class loader parent chain of IMyRemoteIntf:
    weblogic.utils.classloaders.ChangeAwareClassLoader@1715ee2
    -> weblogic.utils.classloaders.GenericClassLoader@123ade0
    -> weblogic.utils.classloaders.FilteringClassLoader@1312cf9

    -> java.net.URLClassLoader@82d37
    -> sun.misc.Launcher$AppClassLoader@e39a3e
    -> sun.misc.Launcher$ExtClassLoader@a39137
    Class loader parent chain of IMyRemoteIntf as reported by r.getInterfaces():
    sun.misc.Launcher$AppClassLoader@e39a3e
    -> sun.misc.Launcher$ExtClassLoader@a39137
    IMyRemoteIntf is in a jar file in WEB-INF/lib of my web application. I
    tried prefer-web-inf-classes = true in weblogic.xml as well as
    prefer-application-packages in weblogic-application.xml (with the
    respective package of the interface).
    Any ideas? I don't know what more I can try. I can access the same
    server with this t3 URL just fine from outside of the WebLogic server.
    Regards

    I meant an issue about multi-connections. Although the socket is shared by all of the connections, each connection in RMI might correspond to a separated thread, I guess. Since the socket is shared by all rmi clients, the RMI channel would be a blocking connection. I am not sure if the RMI in JDK1.4 or above also use the nonblocking new I/O technique. Thanks.

  • Create session bean using interfaces, not implementation classes

    Hi,
    I'm using interfaces and session beans for my persistence/data layer in my adf application.
    I've created a data control for my session bean and during creation of this data control, javabean.xml files are created for the different interfaces that are used in my session bean.
    If I create bindings on these methods, interfaces in jspx-documents I will get errors because he can't find the impl-classes that implement these interfaces.
    When using interfaces in your session bean (as return values or parameters) instead of classes you need to manually create javabean.xml files for the implementation classes.
    It's required by the databindings/datacontrol that the implementation-classes are described in a javabean-format as well? Is this a spec we need to adhere to?
    Could someone verify that you need to create javabean.xml-files for as well the interfaces as the classes when you're working with interfaces in your session beans?
    regards,
    Nathalie

    A patch was released by Oracle to be able to work with Interfaces and so it's not required to work with implementation-classes.

  • How to view COMPONENTCONTROLLER interface 's implement class

    Every WDA has COMPONENTCONTROLLER  ,and it has  interface, How to view class implemented this interface?

    Actually that's not true.  The interfaces get built as you are editing the component and compile like any other class when you activate. They are just hidden from the class builder to keep people from messing around with them directly and to keep from cluttering up the object navigator. They have to be built as you go otherwise SAP would have had to build a special syntax checker and code parser for the ABAP Code Completion for WDA (which we didn't do).
    You can view the interfaces however.  There is a button on the toolbar (or you can press CTRLSHIFTF1 or the menu path GOTO->Controller Interface).
    http://www.flickr.com/photos/tjung/2740591187/
    It displays the interface in a dialog window:
    http://www.flickr.com/photos/tjung/2741429324/
    Also in ABAP 7.1 and higher, the interace is also visible via the code completion via the implementation of the interface in WD_THIS.

  • Retrieve used interface from implementation class

    Hi to everyboby
    I have a remoteObject that implement 2 interface (I1, I2). These interfaces are child of common father interface (I0).
    This remote object is received unmarshalled and casted to one of the to directly implemented interface I1 or I2,
    After that I want to execute a method declared into the interface I0 on the server side, that prints out the name of the interface used during casting after the unmarshall operation on the client side.
    How can I retrieve the name of the current interface used to refer the object into the client side, from the server side?
    Anyone as suggestions?
    thank you very much
    Edited by: dj3mb3 on Jun 10, 2010 5:49 AM

    I'll try to explain in a better way ...
    I have a server with 2 different client and each client communicate to the server with a different interface.
    My needs are to recognize from the server, the type of the client that are operating, and to do this I was thinking to recognize the interface used from the client to interact with the server
    An other option is that, from the client, after retrieving the server and it's cast, a can call a method to pass to the server object, the type of the interface actually used.
    But I think this makes a bit of nonsense because When I receive the marshalled object in my opinion doesn't make sense that i have to say the object it's type (the interface used).
    the object is already alive and I think it has to know the interface used to refer it even if is on another VM
    The cast operation doesn't store nothing into the current object instance?
    local code example (I don't know if with JRMI the situation is different because the different JVM)
    Map foo = new HashTable();
    I need a method like
    foo.curretUsedInterface() ... that return "Map"
    instead of
    foo.getClass().getName() that return "HashMap"
    It's possible to obtain this information or I have to try another idea to make the server distinguish the client type?
    thank you very much for your comprehension

  • Implement multiple remote interfaces

    Hi there, I wanted to write an RMI application with an remote object which implement two different remote interfaces, each has its own remote methods.
    eg:
    public class TestImpl implements Test1, Test2 {
    I only want to allow client to call the methods from Test1 remote interface (without Test2.class in the package). But exception NoClassDefFound of Test2 is caught. The reason I want to do like this is because I have a method in Test2 to unexport the remote object, call by server, so I want to hide it from client.
    I implement the system with Activation, but I couldn't unexport the TestImpl from somewhere else on the same activation group by using Activatable.unexportObject(..). I only can unexport it inside TestImpl remote object itself by calling Activatable.unexportObject(this, true); otherwise, NoSuchObjectException is caught.
    Thanks,
    Jax

    If X and A are in the same activation group, X can
    unexport A as long as it has a reference to the actual
    object A not its stub (because unexportObject() takes
    an impl not a stub).Yes, it's true that X can unexport A because there are within the same JVM. But the problem is I can't get the actual object of A.
    For example:
    // assume this code is within X
    ActivationGroupID agi = ActivationGroup.currentGroupID();
    ActivationDesc desc = new ActivationDesc(agi, "A", location, data);
    ActivationID id = ActivationGroup.getSystem().registerObject(desc);
    Remote remote = id.activate(true);
    The code above will only return a stub.
    Even if I use Activatable.register(desc), it returns a stub as well.
    How do I get the actual object?

  • Best practice for Javadoc comments in both an interface and implementation

    For the Spring project I'm writing, I have interfaces with typically 1 implementation class associated with it. This is for various good reasons. So I'm trying to be very thorough with my Javadoc comments, but I realize I'm basically copying them over from interface to implementation class. Shouldn't Javadoc have a setting or be smart enough to grab the comments from my interface if the implementation class doesn't have a comment? Unless of course there is interesting information about the implementation, it's rare the 2 sets of comments would be different.

    the bean class :)
    But the actual implementor is a class generated by the appserver that delegates to the bean class.

  • How to specify a base class for Remote Interface in Workshop 9.2? -- URGENT

    Hi,
    I am trying to create a UUP EJB in WebLogic 9.2 workshop. I am using @FileGeneration to create my home & remote interfaces. And the generated remote interface is extending javax.ejb.EJBObject;I want my remote interface to extend com.bea.p13n.property.EntityPropertyManager which in turn implements javax.ejb.EJBObject. Can someone tell how i can do it in Workshop?.
    I came across Predefined Variable: remote.baseClass and as per docume
    ntation..."If specified, the value of this variable will be used as the base class for all generated remote classes. Where i should specify it?. @FileGeneration does nt have any option for it. Any help is grtly appreciated.
    Following are my code snippets:
    IMPL Class
    @FileGeneration(remoteClass = Constants.Bool.TRUE,remoteHome = Constants.Bool.TRUE, localClass = Constants.Bool.FALSE, localHome = Constants.Bool.FALSE,remoteClassName = "MyEntityPropertyManager",remoteHomeName = "MyEntityPropertyManagerHome")

  • EJB deployment problem --New remote interface class files are not loaded

    Hi, I face a problem while deploying an ear file in oc4j. I basically get some problems like the method in the remote interface is not implemented in the EJB class. But the implementation is actually available in the EJB class.
    We get this problem when we actually change the signature of the EJB remote methods. The new methods are not referenced by oc4j. Only the old version of remote interface is referenced by oc4j. But the latest version of EJB class is taken. I am using 9.0.3 version of the oc4j. Could you pls help me regarding this problem ?

    Hello,
    I know that I'm not the first one posting this problem, but I can't find an appropriate solution for my problem. When I execute the FlightSeatAvailabilityCheck scenario I got the following error:
    Unable to check flight availability.       
    Error Type:      XI system error
    Error Details:      No implementing class registered for the interface (type ifmmessif, name FlightSeatAvailabilityQuery_Out, namespace http://sap.com/xi/XI/Demo/Agency )
    I have to say that I accidently deleted the proxy but I have recreated and activated the concerning proxy (CO_SXIDAG_FSA_QUERY) and still get the error. I read in this thread: XI 3.0 Demo: Unable to check flight availability: XI System Error that it would help to create a RFC in sm59. Why do I have to do this although I'm using proxies?
    And does it make a difference in which client I create and activate the proxies?

    Hello Sukru
    If you are working already on SAP releases >= 6.20 then you will see all implementing classes if you display the interface in SE80 (tree display -> subnode of the interface).
    Alternatively, you can call method <b>GET_IMPLEMENTING_CLASSES</b> of class <b>CL_OO_INTERFACE</b> (available on >= 6.40, perhaps on 6.20, too).
