Hi Thamayanthi, Thank you for your interest on this project.
In current BPEL visualizer, there are several limitations such as, - It doesn't support all BPEL activities. ( eg: Extenstion activity support - PeopleActivity, E4X ) - Activity alignment problem. - Usability issues with large BPEL files. etc. So the first task of this project is to come up with a new BPEL visualizer tool to overcome above limitations. Other task of this project is, re-use same BPEL visualizer to to display BPEL instance level information. WSO2 BPS uses Apache ODE [1] as the BPEL engine. ODE engine persists instance runtime related data such as current state, activity event information, fault activities etc in to the databases. You can query these data from the ODE database and can be used to visualize instance runtime data in the BPS instance page. So the deliverable of this project would be, 1. Enhance/Re-model exiting BPEL visualizer. 2. Use new visualizer to display BPEL process definitions (.bpel) in WSO2 BPS BPEL package view.( Static view ) 3. Re-use same visualizer to display BPEL process instance events related information in BPS BPEL instance view. As the first step, study the existing WSO2 BPS BPEL visualizer. You can find the existing visualizer source code from [2].
