Specifying Applications

Activities performed within the context of a business process may have to execute application logic. This application logic is defined by a concept called application. For more details on applications, refer to Applications. Applications in the Stardust Documentation.

The following application types are supported in the Web-based modeler:

• Generic Camel Endpoint Application
• Message Transformation Application
• Web Service Application
• UI Mashup Application
• REST Service Application
• Script Invocation Application
• E-Mail Send/Receive Application
• Stored Procedure Application Overlay
• SQL Application Overlay
• SMS Invocation Overlay
• Templating Invocation Application

Chapter Using imported Plain Java Applications gives details on how to use imported Plain Java Applications, which are not supported for editing in the Browser modeler, but can be imported to be used for modeling.

This section helps you to work with applications in the Business Process Modeling perspective.

Creating Application

You can create following application types:

• Message Transformation Application
• Generic Camel Endpoint
• Web Service Application
• UI Mashup
• REST Service Application
• Templating Application
• Scripting Application
• SQL Application

To create any of these applications, perform the following steps:

1. Expand the My Process Models panel displayed in the left pane of the Business Process Modeling perspective.
2. Make sure that a model is created using the Create Model option
3. Expand the created model
4. Right-click the Applications node and select the type of the application you want to create.

Figure: Create Application

Renaming Application

Under the Application node, right-click the application name and select Rename .

Figure: Rename Application

Rename can be performed in the My Process Models panel, property panel of the element, and by double-clicking element in the Process Diagram canvas.

Deleting Application

Under the Application node, right-click the application and select Delete.

Viewing and Editing Application Properties

To view and edit the properties of any application, select the application under the Applications node in the My Process Models panel.

Figure: Select Application

The properties of the selected application get displayed.

Working with Service Wrapper Process Wizard

The Service Wrapper Process Wizard allows creating a process definition with SOAP and/or REST interface based on a service application, without the need to model it manually. It supports service definition with one IN and OUT access points on a structured data type only. The Request Data (any Structured Data Type in the same model) and Response Data (any Structured Data Type in the same model) are used as IN and OUT formal parameter of the process interfaces created. A Service Wrapper Process can be transient and/or persistent (default).

If the Create Test Wrapper Process check box is selected, another test process is created. This process can be used as manual test process to invoke the original process from within the process portal and not via SOAP and/or REST.

Figure: Service Wrapper Process Wizard

Under the model node, following elements get created:

• Data
  • Request Data
  • Response Data
• Process
  • The Wrapper Process defines:
    • A process interface (SOAP and/or REST) with Request Data as input parameter and Response Data as output parameter
    • A Service Activity using the service on which basis the wizard has been initiated
    • A possible Rules Activity for post-processing logic

    
    Figure: Service Wrapper Process

  • The Test Process defines:
    • A Manual Trigger for the Administrator role
    • A Manual Activity gathering content for Request Data
    • A sub-process invocation of the actual wrapper process
    • A Manual Activity displaying content of Response Data

In case you want to create a test process after the wrapper process is created, right-click the wrapper process and select the option Create Interface Test Process. The test process gets created.

Figure: Create Interface Test Process

Create Interface Test Process

This creates a test process to test your original process.

Figure: Interface Test Process

Specify following details:

1. Target Model - Select the target model for which you want to create interface
2. Process Definition Name - Specify process name
3. Executing Participant - Select participant to execute the test process
4. Data Input Activity Name - Specify data input activity name
5. Process Interface Invocation Activity Name - Specify activity name from which interface is invoked
6. Data Output Activity Name - Specify data output activity name

The created wrapper process becomes Auxiliary process, by default.

Working with Referenced Application

If the Public Visibility check box is selected of the application, then it can be referenced in the consumer model. To reference the application, drag and drop the application from the provider model to the consumer model.

Figure: Drag and Drop the Application to Consumer Model

Based on the application type, it gets converted to appropriate task types.
