Introduction to VisiBroker

For the CORBA developer, Micro Focus provides VisiBroker for Java and VisiBroker for C++ to leverage the industry-leading VisiBroker Object Request Broker (ORB). These two facets of VisiBroker are implementations of the CORBA 3.0 specification. See “VisiBroker CORBA Compliance” for further details.

VisiBroker Overview

VisiBroker is for distributed deployments that require CORBA to communicate between both Java and non-Java objects. It is available on a wide range of platforms including different hardware, operating systems, compilers and Java Development Kit (JDK) versions. VisiBroker solves all the problems normally associated with distributed systems in a heterogeneous environment.

VisiBroker includes:

•	VisiBroker for Java and VisiBroker for C++, two implementations of the industry-leading Object Request Broker.

•	VisiNaming Service, a complete implementation of the Interoperable Naming Specification in version 1.3.

•	GateKeeper, a proxy server for managing connections to CORBA Servers behind firewalls.

•	VisiBroker Console, a GUI tool for easily managing a CORBA environment.

•

Common Object Services such as VisiNotify (implementation of Notification Service specification), VisiTransact (implementation of Transaction Service specification), VisiTelcoLog (implementation of Telecom Logging Service specification), VisiTime (implementation of Time Service specification), and VisiSecure (security service).

VisiBroker Features

VisiBroker offers the following features:

•	“Out-of-the-box” security and web connectivity.

•	Seamless integration to the J2EE Platform, allowing CORBA clients direct access to EJBs.

•	A robust Naming Service (VisiNaming), with caching, persistent storage, and replication for high availability.

•	Automatic client failover to backup servers if primary server is unreachable.

•	Load distribution across a cluster of CORBA servers.

•	Full compliance with the OMG's CORBA 3.0 Specification.

•	Integration with the JBuilder integrated development environment.

•	Enhanced integration with other Micro Focus products including AppServer.

VisiBroker CORBA Compliance

VisiBroker 8.5 is compliant with version 3.0 of the CORBA specification from the Object Management Group (OMG). All changes between the earlier version 2.6 and version 3.0 are implemented. Note that VisiBroker:

•	Supports General Inter-ORB Protocol (GIOP) to standard 1.2; GIOP 1.3-related features are not implemented.

•	Does not support the CORBA Component Model (CCM) or Fixed types.

For more details, refer to the CORBA specification located at http://www.omg.org/.

Both methods launch the Help Viewer in a separate window and give you access to the main Help Viewer toolbar for navigation and printing, as well as access to a navigation pane.
