Summary of Material
| We describe the basic HPcc Pragmatic Object Web view of distributed systems and how one can use to build hybrid high performance commodity systems |
| We then describe briefly the WebWisdom Educational support system with its database backend. |
| A key service is collaboration which can be used for distance education and other activities critical to a good learning environment |
| We describe application of Tango to our course at JSU |
| We finish with a description of Scivis simulation system |

| Basic Vision: The current incoherent but highly creative Web will merge with distributed object technology in a multi-tier client-server-service architecture with Java based combined Web-ORB's |
COM(Microsoft) and CORBA(world) are competing cross platform and language object technologies
|
Need to abstract entities (Web Pages, database entries, simulations) and services as objects with methods(interfaces)
|
| How do we do this while infrastructure still being designed! |
| Major Commercial Java Activity today is on Server NOT Client |

One can anticipate this by building systems in terms of Java objects e.g. develop Web-based databases with Java objects using standard JDBC (Java Database Connectivity) interfaces
|
Even better use (Enterprise) Javabeans which are Java's (middle tier) or client componentware offering visual interfaces, containers (here they are consistent with CORBA standard) and standard software engineering interfacing rules

| Java has potential to be a better environment for "Grande application development" than any previous languages such as Fortran and C++ |
| The Forum Goal is to develop community consensus and recommendations for either changes to Java or establishment of standards (frameworks) for "Grande" libraries and services |
| These Language changes or frameworks are designed to realize "best ever Grande programming environment" |

| HPcc is High Performance commodity computing |
Encapsulate services (from databases to instruments to MPP's) as middle tier distributed objects using an approach that will evolve to COM/CORBA in future but is deployable today
|
Establish Java Frameworks and Equivalent CORBA Facilities
|
| This already gives you an approach to seamless access and a framework for composing complex metaproblems by linking programs together or programs to databases |

Integrates protocols for inter-tier communication
|
| CORBA - JWORB is an OMG compliant ORB written in Java and acting as middleware in the 3-(or more)-tier CORBA applications |
| HTTP - JWORB is a Web Server using CORBA services where possible |
| COM - we are planning to implement COM/CORBA bridge as specified by OMG to enable interoperability between CORBA and DCOM objects |
| RMI - JWORB is written in Java so the interface to the 100% Pure Java world is naturally available via RMI -- new RMI uses IIOP |
| W3C - we intent to implement new Web Object Model (XML+RDF+DOM) using CORBA services in JWORB |

Taught using Tango/WebWisdom over Internet (now DREN via CEWES) every Tuesday and Thursday from Syracuse
|
| Jackson State major HBC University with many computer science graduates |
Do not compete with base courses but offer addon-on courses with "leading edge" material (Web Technology) which give JSU graduates skills that are important in their career
|
Needs guaranteed 30 (audio) to 100 (two way) kilobits per second bandwidth assuming course material mirrored at JSU
|
| Hope to offer our analogous K-12 Java Academy to middle and high school students |
| JSU will use Tango/WebWisdom to teach to others -- train the trainers |

| Scivis is a client-server data visualization and analysis system which takes full advantage of Java. |
| The purpose of this system is provide researchers with a customizable data analysis system to aid their research. |
| We also provide a collaborative framework, where the users can exchange data and their own personalized filters. |
| Available via http://kopernik.npac.syr.edu:8888/scivis |
NOTE: Scivis is not browser-based. It contains a visualization server and a Java application.

| A filter is an action which is performed on a data set(s) to create a new data set based on this action. |
| We provide an infrastructure for users to create their own filters. |
| Filters can be created on-the-fly and can be shared among collaborators. We provide a Wizard to create filter templates. |
