Rogue Wave JViews Diagrammer Sample: Business Process Monitoring

Description

This sample shows how Rogue Wave JViews Diagrammer can be used to monitor a process by displaying changes in the business model in real time.

How to Use the Sample

• Press the Start/Stop button to start the animation.
• Press the Loop button if you want the animation to loop continuously.
• The activities of the process are highlighted as the simulator follows the process flow.
• Press the Start/Stop button again to stop the animation.

How to Run the Sample as an Application

This sample can also be run as an application. The installation directory contains an executable JAR file, diagrammer-monitoring.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Rogue Wave JViews.

Then, go to the installation directory of the sample and type:

ant run

Topics Covered

• Display the status of a process in real time.

Detailed Description

This sample shows how Rogue Wave JViews Diagrammer can be used to monitor a process by displaying changes in the business model in real time.
The diagram represents a business process. A simulator goes through the process by following the flow of activities. When a decision activity is encountered, the simulator chooses one of the routes randomly.
As the simulator goes through the nodes and links of the graph, it sets their "status" property to "active", and then "done". This simulates a real-life process where the activities are executed one after another.
The style sheet used in the example displays the nodes and links with different graphical attributes depending on their status:

• Active nodes have an animated icon and a bullet representing a token going through a workflow.
• Active links have animated dashes and the token bullet.
• Activities that are finished have a check mark.
