corba security

Because in the attempt to use BCB 4 to access Nameservice, encountered some strange problems, and Visibroker example can be used to bcc32 normal compilation, I decided to do a program from scratch to see where the problem. Toss all night, the conclusion is to do the server or not the CORBA Server Wizard good. (I still don't understand why?) ） 1, file| New, Multitier,corba IDL File: interface Order{string

For CORBA objects, the following two life cycle events are important: • The life cycle of creating--corba objects begins with the creation of events. CORBA objects are typically created from factory objects, that is, objects provide operations to create new objects. Recall that, at the IDL level, CORBA does not have a

Absrtact: This paper introduces the characteristics of Jcorba and how to deploy the Java CORBA component in Oracle Application server through a Jcorba application example. The rapid development of the Internet has changed the traditional way of information exchange and the way enterprises operate, and it has become a medium for many new industries such as E-commerce, self-service, online shopping and online transactions. More and more enterprises b

The code shown here may not be exhaustive because different orbs have different ways of accessing the CORBA service, so whatever the example will depend on the specific vendor (the following example uses Javaidl, which is a free product of sun Company). It provides a simplified version of the Orb, a naming service, and a "idl→java" compiler. In addition, because Java is still in the early stages of development, it does not include all

. sometimes warning-level logs appear to be time out exceptions when a network link is created. Therefore, the source code of checkout CORBA traces the corresponding code lines and finds that it is indeed an exception caused by timeout, the corresponding parameters provided by CORBA are configured for this time. Therefore, the Time Out is set to 60 seconds. The original value of this parameter is 10 seconds

1. Overview: In the previous articles have been implemented CORBA environment configuration, Eclipse simple development implementation; In the daily development, the common ways of remote invocation and implementation of CORBA interface are two kinds: IOR (file mode) and Nameservice (naming service mode); The following is the IOR file mode specific service and client implementation code, as business require

One of the main features of CORBA, as we already know, is support for RPC (remote procedure calls). Using this technique, our local object can invoke the method within the remote object of the location. Of course, there is already an inherent Java feature that can do exactly the same thing: RMI (refer to chapter 15th). Although RMI makes it possible to make RPC calls between Java objects, CORBA can rpc betw

is based on their logical relationship in the flowchart. We want to identify generations of different Corba:boa (basic object adapters) and POA (Portable object adapters). This distinction will allow us to define two important milestones in the evolution of the core orb architecture. 1, Boa Generation Boa generation of CORBA Architecture object adapters are the primary interfaces that applications use to access orb functions. It includes. An inter

As we know, the POA specification defines a CORBA object as an abstract entity with identity, interface, and implementation. From the client's point of view, the object is represented as an object reference, the object reference encapsulates the object interface type and identity, and contains enough information to locate the object's implementation. But what about the server's point of view? 　　1. Servo ObjectThe POA specification introduces the conc

Below is a simple example of a CORBA program Download the source file 1. Produce a IDL file like this Hello.idl Module HelloApp { Interface Hello { String SayHello (); }; }; 2. Produce stub and skeleton files through Idltojava.exe Idltojava Hello.idl Idltojava is isn't include in the JDK. But can download it from Idldojava. 3. Write a server program like this Helloserver.java Import helloapp.*; Import org.omg.cosnaming.*; Import org.omg.cosnaming.nami

CORBA Concepts (GIOP, IIOP, IOR, ORB, IDL) CorbaThe common Object request broker (Scheduler) program architecture (Common object Request broker Architecture), abbreviated to CORBA, is an object management organization (objects Management Group) in response to the demands of today's fast-growing hardware and software collaboration capabilities. In short, CORBA al

provide support for J/direct, RNI, and java/com.Our final study is CORBA, which enables our Java objects to communicate with other objects-regardless of where they are physically located or in which language they are implemented. CORBA is different from all the techniques mentioned above, because it is not integrated into the Java language, but instead uses the integration technology of other vendors (thir

In the previous article, the implementation of CORBA based on IOR was described, and a common one is based on nameservice implementation; CORBA's object naming service is to give the object instance a name so that the user can get an instance of the object by these names. Object Naming Service is the basic mechanism by which objects on the Orb find other objects. A name is a human-readable value used to identify an object, the naming service maps the

Brief introduction DB2 UDB provides a framework for writing custom security plug-ins that administrators can use to perform DB2 UDB authentication. This framework is introduced in the DB2 UDB V8.2, and also supports plug-in authentication based on the Universal Security Service Application Programming interface (Generic, application programming Interface,gss-api). Many DB2 UDB administrators use the GSS-A

The words in Windows core programming cannot dispel doubts. Let's explain it to us in msdn. If you want to give a detailed introduction, go to msdn and take a closer look.

An access token is the information used by the process to access the data that indicat
