This document briefly describes a brief usage of the SOAP workflow framework when developing a service consumer.

Getting Started

The first thing to do is to check the service endpoint end-point description page and WSDL document using the provided endpoint end-point address.

Usually the address for endpoint of the end-point description page looks like this:

  • http://<host>:<port>/application-name/InvokerService

and the WSDL location like this:

  • http://<host>:<port>/application-name/InvokerService?wsdl

...

Accessing the end-point description page you should see display something like this:

and when trying it is attempted to access the WSDL location you should be able to see , the valid WSDL document should be displayed.

When you have the WSDL document, you can start generating the DTO classes. Many programming languages have it's their own tools for class generation from WSDL.

One of the easiest ways to do this in JAVA Java is to use JAX-WS and Maven with a plugin called jaxws-maven-plugin. The example Maven pom.xml file could look like this 

When you have successfully generated the class sources, you can start developing your service client using these classes and invoking the workflows.

Place the WSDL document in <project_dir>/src/wsdl and run the following command to generate the class source files:

Code Block
mvn generate-sources

When you have successfully generated the class sources, you can start developing your service client using these classes and invoking the workflows.

...

</xs:schema>

Assuming the workflow must be invoked which expects you to send the following structure.:

Request:

Key

Value type

Mandatory

Description

CONTEXT

ComplexValueDTO

true

Context object, mandatory in each request.

...

Key

Value type

Mandatory

Description

LANGUAGE

StringValueDTO

true

Language code. EN, FR, DK, etc. Used for displaying error messages.

OPERATOR

StringValueDTO

true

Operator information.

BRAND_ID

StringValueDTO

false

Id of the brand if applicable.

Then then your client code would look something like this:

...

This approach gives a lot of flexibility as the changes to the service maybe may be applied rapidly, it 's is just a matter of adding another DTO to a value list.

Note: You can also have a tree-like structure using ComplexValueDTO objects, that means, i.e. you can have a list of ComplexValueDTO objects inside another ComplexValueDTO object. The example would look like this:

...

This becomes useful when you need have to transfer some kind of very complex object and pass it to the workflow framework.
