WebFlow - a visual programming environment for the Web with real-time dataflow graph authoring tools
3-tier multi-server system with Web browser / Java applet front-end, Java Web Server middleware and (Java) computational modules in the backend
Early prototype - pure Java system, controlled by servlet based Session, Module and Connection Managers
POW middleware will support all languages
Used to build both linked modules and as framework for "wrapping legacy codes" as "distributed scientific objects"

JWORB - Java Web Object Request Broker - multi-protocol middleware network server (HTTP + IIOP + DCE RPC + RTP + ..)
Current prototype integrates HTTP+IIOP i.e. acts as Web Server and CORBA Broker
Next step: add DCE RPC support to include Microsoft COM
JWORB - our trial implementation of POW

JWORB (Java Web Object Request Broker) is our multi-protocol (now HTTP + IOOP) middleware server
Difficult to demo as middleware invisible...
We illustrate HTTP and IIOP integration by timing a ping call over IIOP channel while invoking a Web page from JWORB - to notice a transient ping performance drop
