Motivation
Building a web-based visual component to support online collaborative business process management.
Requirement: Online collaborative business process management requires the web-based output component and the web-based input component as well
Weakness: Traditional web-based visual components pay much more attention to web-based visual output than input
Try to Provide: A web-based visual component that supports both web-based visual output as well as input

The XML-based Information Repository
Three levels tree structure The top level is the
name of the business process repository
The middle level are the names of the business processes
The leaf level are the .xml files that store the business process elements and relationships

The HTTP-based Communication Module
The source code to send the information from a web client to the web server
public static String sendDataToServer(String data){ try { StringBuffer sb = new StringBuffer();
URL url = new URL("http://138.25.13.183:8888/pwm/servlet/RPMSServlet");
URLConnection uc = url.openConnection(); uc.setDoOutput(true); uc.setDoInput(true); uc.setAllowUserInteraction(false);
DataOutputStream dos = new DataOutputStream(uc.getOutputStream()); dos.writeBytes(data); dos.flush(); dos.close();
…… }

The Applet-based Visualization Module
A business process BP is represented by a countable set of process elements PE and a countable set of element relationships ER, i.e., BP = {PE, ER}.

Future Work
more functions: display different process element using
different shape of graph
more input interfaces: input different element
