We are using Visibroker for Java 3.4 in our exisiting product. We use osagent and do static binding. We have an immediate need to deploy this application (Stand alone Java application communicating to application server thru CORBA) in Internet.

I am trying to build up a Development environment (using JBuilder) to write Corba Object Implementations, Corba Object Requests and Corba Server Implementations, all in Java. I am using Visibroker 4.0. Please help.
JBuilder 3 Enterprise Edition comes with support for VisiBroker 3 built in. It understands IDL files, invokes the IDL compiler, will build sample implementations, includes the VBJ libraries, et...more
I am implementing a CORBA server object in CORBA client side. I wanted to start this CORBA server object from a client program but in a separate JVM. How can I do that?
CORBA's Basic Object Adaptor supports object activation on demand. The client just uses the object reference and if an object server implementing the object is not running, the BOA will automatic...more
Often times a consumer is only interested in some of the events produced by a supplier. For example, consider a stock portfolio object. It is interested in stock change events for particular stock...more

Event channels are themselves suppliers and consumers of events. As such, they can be chained together. Consider the following scenario: a supplier supplies events to multiple nearby consumers an...more
In pull-style event communication, the consumer of the event invokes a pull operation on the supplier. The pull operation returns the data associated with the event. The pull operation blocks unti...more
In push-style event communication, the supplier of the event invokes a push operation on the consumer. The push operation takes a single parameter which provides the data associated with the event.more
The data associated with an event are described by a IDL any type. An any is a self describing structure that can represent any CORBA data type. Thus, the data type is known at runtime but not at ...more
An event channel is a shared resource used by the suppliers and consumers of the events. This leads to questions of management of the resource. For example, how is the channel created in the first...more
An event channel is an object implemented by the CORBA Event Service. An event channel decouples the communication between suppliers of events and consumers of events. An event channel implements ...more
Yes. Both persistent and transient object references are supported in CORBA. Transient object references fail to operate once the process creating the object reference terminates. Persistent objec...more
The fundamental mechanism for obtaining object references in the distributed object system is as parameters and results of requests. Everything else is built on top of this. So you can pass an obj...more
CORBA 2.0 defines a network protocol, called IIOP (Internet Inter-ORB Protocol), that allows clients using a CORBA product from any vendor to communicate with objects using a CORBA product from an...more
The basic CORBA paradigm is that of a request for services of a distributed object. Everything else defined by the OMG is in terms of this basic paradigm. The services that an object provides are...more
