White Papers

  • OpenFusion CORBA Overview This whitepaper provides an overview of the the most comprehensive range of CORBA solutions available. OpenFusion is PrismTech’s premier suite of CORBA products and consists of technologies targeted to meet the needs of customers developing mission-critical software systems.
  • Strong Security Protection for OSA Parlay Gateways & Servers Whitepaper Using the Xtradyne Domain Boundary Controller (DBC) to strengthen the security and resilience of OSA/Parlay Gateways and Application Servers for 3rd party access via private and public data networks.
  • Security Hardening for J2EE with the IIOP DBC Whitepaper RMI access to EJB servers in the internal network by presentation tier clients (such as servlets in Web server) running in the DMZ is critical but can be securely enabled and reliably controlled. The IIOP Domain Boundary Controller as an application layer security gateway between the Web server and the EJB server effectively shields the business logic and data in the backend as well as the internal network as a whole against possible (e.g., RMI-based) attacks from within the DMZ and from the...
  • Securing Web Services with SOAP security proxies Whitepaper Although in principle independent of any particular messaging protocol, Web Services are primarily accessed using SOAP over HTTP in practice. As SOAP provides no message security at all, other ways of securing messages are necessary. This paper summarizes the most important security model for SOAP, WS-Security and its related specifications. We explore the advantages of one particular approach to implementing Web Services security, security proxies, and compare this approach to library-based...
  • High Availability & Scalability of the Web Services Domain Boundary Controller Both the Xtradyne Domain Boundary Controller (DBC) products (WS-DBC and I-DBC) provide linear scalability and unlimited support for various high-availability scenarios. A suitable solution guaranteeing both for any DBC installation can be chosen from a set of commonly accepted and widely tested approaches and technologies.
  • Firewall Security for CORBA & J2EE / EJB with the IIOP Domain Boundary Controller Whitepaper CORBA and Java(tm) RMI based applications can be directly and securely made accessible to users outside the internal network, i.e. outside the firewall, by adding an IIOP Domain Boundary Controller component to the existing firewall installation. This security gateway solution provides uncompromised firewall security and complete 4A security for CORBA and EJB servers. This white paper covers the special security problems of IIOP and firewalls, the productized solution, and typical operation...
  • OpenFusion JMS - CORBA Notification Service Interworking Whitepaper The asynchronous communication paradigm is recognized as the most flexible and reliable way to communicate between distributed applications. JMS is the native API for Message Driven EJBs. Notification Service is the native API for event Driven CORBA applications. The OpenFusion Notification Service-JMS bridge is a simple and seamless way to integrate JMS and Notification Service. Since no changes are required for either the EJB side or for the CORBA application side, the OpenFusion NS-JMS...
  • OpenFusion Notification Service V4 Whitepaper PrismTech's next-generation implementation of the Object Management Groups CORBA Notification Service, OpenFusion Notification Version 4 is a sophisticated event-driven messaging system supporting both guaranteed message delivery (store-and-forward) and content-based routing. Version 4 offers dramatically increased message throughput and improved scalability over PrismTechs market-leading Version 3 release. Together with enhanced management facilities and a modular architecture, Version 4...
  • OpenFusion Naming Service Whitepape In object oriented systems a variety of resources may be available. These are often identified by object references, which seldom bear any relationship to the type of resource. For instance, in order that people do not have to remember multiple telephone numbers they often use a telephone directory and look up their requirements by known, easily memorable names. The Naming Service is an object directory for distributed systems, which allows such names to be associated with different resources.
  • OpenFusion Trading Service Whitepaper This sophisticated mechanism for locating servers is based on description of requirements, rather than simple names. Server objects register their services with the Trading Service, specifying a set of property values that describe the service that they are offering. Other (client) objects can use the Trading Service to locate a server that provides a required service, based on these property values. The Trading Service matches the required service property values with those supplied by the...
  • Security Enables New Web Services Telecom Case Study XML Web Services provide a powerful and flexible basis for telecommunications operators to create value-added services for their customers and to optimize their business processes. This case study examines how in introducing Web Services a telecommunications operator was confronted with the very high security requirements typical for the telecoms industry. Through the deployment of the Xtradyne Web Services security gateway, all security requirements could be met so that Web Services could go...
  • OpenFusion e*ORB CORBA for Digital Signal Processors The DSP remained until recently the last frontier for CORBA. However, modern applications demand extensive functionality combined with great flexibility in ever smaller devices and it is this that has driven the porting of CORBA to DSPs. This paper describes how running CORBA on a DSP achieves flexibility and simplifies integration by exposing the services offered by the DSP far more widely than is possible with any other technology.

  • OpenFusion RTOrb Java(tm) Edition Whitepaper Distributed middleware conforming to the Object Management Group’s (OMG’s) language-neutral CORBA specification is well established as a technology for integrating diverse systems and is used extensively for mission and business critical applications in many industry sectors such as defense, telecommunications and manufacturing. With the publication of the Real-Time CORBA Specification, the OMG extended the benefits of CORBA to the Real-Time domain. However, up until very recently developers of...
  • Protecting Web Services with the XML / SOAP Security Gateway XML Web Services can be securely exposed to users outside the internal network by adding an XML / SOAP security gateway. The Web Services Domain Boundary Controller enables comprehensive XML based application security management (4A) and detailed content inspection. This white paper examines how the Web Services Domain Boundary Controller can provide a complete solution to the challenge of secure Web Services.
