Stardust/Knowledge Base/Reference Project

Purpose

The Charity Reference Project is intended to explain to the Stardust community and beyond for the Eclipse SOA Project how BPM technology can be used to created a complete application with minimal programming effort and maximum involvement of domain experts.

Scenario

The Federal Charity institution of the fictitious country Neverland provides an Internet platform for charity organizations to distribute their benefits to those in need. Charity institutions can register and describe their rules for accepting beneficiaries. Beneficiaries can apply for benefits such as vacation funding.

Main Elements

Processes, Events and Activities

  • Charity Organization Registration and Approval
    • Data Entry
    • Address Verification
    • Review
    • Approval/Rejection
  • Vacation Request
    • Data Entry
    • Address Verification
    • Dispatching to Charity Organization
    • Review
    • Approval/Rejection

Participants

  • Platform Operators from the roof organization running/operating the system
  • Administrators of the charity organizations
  • Applicants would only be implicit participants kicking of workflows via a little portal and receiving notifications

Services

  • Address Validation Specifications managed in EasySOA, implementation prototyped in OW2 FraSCAti Studio
  • HTML/JS UI Component for Organization Review
  • Simplistic HTML5 web portal for Charity organization registration (kicking off first process) Application for vacation funding (kicking off second process)

Data Model

  • XSD
  • Charity Organization (Structure)
  • Vacation Funding Request (Structure)
  • Beneficiary (Structure)
  • Address (Structure)
  • Country (Structure)
  • Used across tools (BPM, WS)

Running the Project

  • Install Stardust for Helios or Kepler
  • Create a Dynamic Web Project charity with Stardust Profile enabled (for more details see the Support Case example in the documentation).
  • Load the charity-portal Utility Project from Examples in Stardust Git into your workspace
  • Copy the Process Model to a folder proces-models (or the like) in your Dynamic Web Project
  • Add the charity-portal Utility Project to your Deployment Assembly of the charity project (Properties > Deployment Assembly > Add Project)

After these steps your Outline should look like this

After starting the server you should be able to open

  • [http:/localhost:8080/charity http:/localhost:8080/charity] to access the Stardust Process Portal and
  • [http:/localhost:8080/charity/plugins/charity-portal/public/homePage.htm http:/localhost:8080/charity/plugins/charity-portal/public/homePage.htm] to access the Neverland Charity Portal.

Selected Implementation Aspects

Charity Portal

The Charity Portal is a simple HTML/JS-based implementation which leverages

Processes are started via REST calls from the class ServiceAdapter

   jQuery.ajax({type : "POST",
		beforeSend: function (request)
		{
		   request.setRequestHeader("Authentication", self.getBasicAuthenticationHeader());
		},
		url : this.getProcessStartUrl("CharityOrganizationRegistration"),
		contentType : "application/xml",
		data : payload}).done(function() {
		      deferred.resolve();
		   }).fail(function() {
		      deferred.reject();
		});

using a Deferred Pattern for synchronicity.

The XML payload to initialize the Process Data is assembled manually from the JSON objects used in the UI.

   var payload = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
					
   payload += "<ser:Args xmlns:ser=\"http://eclipse.org/stardust/models/generated/Charity\" " +
      "xmlns:cha=\"http://www.infinity.com/bpm/model/Charity/CharityOrganization\" " +
      "xmlns:add=\"http://www.infinity.com/bpm/model/Charity/Address\">\n";					
   payload += "   <ser:CharityOrganization>\n";
   payload += "      <cha:CharityOrganization>\n";
   payload += "         <name>" + organization.name + "</name>\n";
   payload += "         <description>" + organization.description + "</description>\n";
   payload += "         <beneficiarySelectionRules>" + organization.beneficiarySelectionRules + "</beneficiarySelectionRules>\n";
   payload += "         <add:address>\n";
   payload += "            <street>" + organization.address.street + "</street>\n";
   payload += "            <city>" + organization.address.city + "</city>\n";
   payload += "            <postalCode>" + organization.address.postalCode + "</postalCode>\n";
   payload += "            <state>" + organization.address.state + "</state>\n";
   payload += "            <country>" + organization.address.country + "</country>\n";
   payload += "         </add:address>\n";
   payload += "      </cha:CharityOrganization>\n";
   payload += "   </ser:CharityOrganization>\n";
   payload += "</ser:Args>\n";

This might be replaced by an automated conversion, e.g. with json2xml. Volunteers to help are welcome to submit via Gerrit.
