Deleting an application

An application cannot be deleted if it is used in a process.

Deleting a parameter

A parameter cannot be deleted if its application is used in a process.

Assembly application

This application allows you to declare a .NET class method as a workflow application. It is the fastest solution to develop a custom workflow application (compared to web services). The execution performance is exceptional because WorkflowGen instantiates the assembly directly without network communication or web service authentication.

Example

1. Copy a sample .dll assembly into a WorkflowGen bin folder.

2. In the Administration Module, click Applications and then New application.

3. Enter the following information in the appropriate fields:

   • Name: SAMPLE_GET_STRING

   • Description: Returns a string with a ! (exclamation point)

   • Type: Assembly

4. Assembly full name or path: WorkflowAppSample

5. Click Save.

• Class full name: Select WorkflowApp.Test

  • Method: Select GetString

These parameters are automatically generated:

• IN: message (Text)

• OUT: RETURN_VALUE (Text)

You can now use this workflow application in your process.

WCF service application

This application allows you to declare a WCF service client proxy .NET class method as a workflow application.

Example

1. In the WorkflowGen Administration Module, click Applications and then New application.

2. Enter the following information in the appropriate fields:

   • Name: WCFSERVICE_SAMPLE_GET_STRING

   • Description: Returns a string with a ! (exclamation point)

   • Type: WCF service

3. Assembly full name or path: WorkflowAppWCFSampleTest

4. Click Save.

• Class full name: Select workflowAppWCFSampleTest.ServiceClient

  • Method: Select GetString

These parameters are automatically generated:

• IN: message (Text)

• OUT: RETURN_VALUE (Text)

You can now use this workflow application in your process.

• Name: WCFSERVICE_SAMPLE_GET_STRING

WSDL web services

Overview

WorkflowGen supports web services based on the SOAP standard. This means that web services can now be integrated into WorkflowGen to be used by process actions, without the need to program them. WorkflowGen can now use predefined web services and reference them by using their WSDL (Web Services Description Language) file.

A URL to the WSDL file defining the web service is required to display the available web methods that can be called by WorkflowGen. Once the WSDL is referenced and saved (in the WorkflowGen application definition), and one of its defined web methods are selected, the WorkflowGen application parameters are automatically generated.

The data types of the parameters are mapped to the corresponding WorkflowGen data types (numeric, text, datetime). All complex XML types are mapped to a WorkflowGen file data.

Public web services

Public web services are web services that are available for public re-use. To reference one as a WorkflowGen Application, follow the example below.

Creating a WSDL web service

1. In the Administration Module, create a new WorkflowGen application and define the following:

   • Name

   • Description

   • Type: Web service

   • Username: A valid WorkflowGen Administrator

   • Password: The valid password for the username

2. Reference a web service and WSDL by defining a URL to a valid web service and to its related WSDL file and save the application. 📌 URL example:

   http://quickstarts.asp.net/QuickStartv20/webservices/Samples/MathService/vb/Server/MathService.asmx

   📌 WSDL example:

   http://quickstarts.asp.net/QuickStartv20/webservices/Samples/MathService/vb/Server/MathService.asmx?WSDL

3. Select the web method to use. The WSDL defines which web methods are available to be used. Once you select a web method and save the application, the associated parameters are automatically mapped and the application may now be used by process actions.

Private web service example

Overview

Private web services are web services that are not available for public re-use. They generally use a secure URL that requires the proper authentication. To reference one as a WorkflowGen application, follow the example below.

Creating a WSDL web service

1. In the Administration Module, create a new WorkflowGen application and define the following:

   • Name

   • Description

   • Type: Web service

   • Username: A valid WorkflowGen Administrator

   • Password: The valid password for the username

2. Reference a web service and WSDL by defining a URL to a valid web service and to its related WSDL file and save the application.

   The examples below demonstrate the use of a web service located on a SharePoint 2007 website. In this example, the web service is called lists.asmx. For more information, see http://msdn2.microsoft.com/en-us/library/ms445760.aspx. 📌 URL example:

   http://myspsserver/_vti_bin/lists.asmx

   📌 WSDL example:

   http://myspsserver/_vti_bin/lists.asmx?WSDL

3. Select the web method to use. The WSDL defines which web methods are available to be used. Once you select a web method and save the application, the associated parameters are automatically mapped and the application can now be used by process actions.

WSDL web service action: other parameters

Overview

WorkflowGen will create some extra parameters when referencing a WSDL. Other parameters can also be used in addition to those already defined in the WSDL file.

Other parameters

The other parameters that are defined by WorkflowGen are:

• RETURN_VALUE: If the web service returns a value, WorkflowGen will automatically add an OUT parameter.

• WFG_WS_URL: Specify a web service URL to override the predefined URL.

• WFG_WS_USERNAME: Specify a username to override the predefined username.

• WFG_WS_PASSWORD: Specify a password to override the predefined password.
