Getting Started
The first thing to do is to check the service end-point description page and WSDL document using the provided end-point address.
Usually the address 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
...
should
...
display
...
something
...
like
...
this:
and when it is attempted to access the WSDL location, the valid WSDL document should be displayed.
When you have the WSDL document, you can start generating the DTO classes. Many programming languages have their own tools for class generation from WSDL.
One of the easiest ways to do this in Java is to use JAX-WS and Maven with a plugin called jaxws-maven-plugin.
When you have successfully generated the class sources, you can start developing your service client using these classes and invoking the workflows.
The WSDL and data types XSD definitions:

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. |
*CONTEXT*:
|| 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 your client code would look something like this:
{code:language=java} |

This
...
approach
...
gives
...
a
...
lot
...
of
...
flexibility
...
as
...
the
...
changes
...
to
...
the
...
service
...
may
...
be
...
applied
...
rapidly,
...
it
...
is
...
just
...
a
...
matter
...
of
...
adding
...
another
...
DTO
...
to
...
a
...
value
...
list.
...
Note:
...
You
...
can
...
also
...
have
...
a
...
tree-like
...
structure
...
using
...
ComplexValueDTO
...
objects,
...
i.e.
...
you
...
can
...
have
...
a
...
list
...
of
...
ComplexValueDTO
...
objects
...
inside
...
another
...
ComplexValueDTO
...
object.
...
The
...
example
...
would
...
look
...
like
...
this:
...
| Code Block | ||||||
|---|---|---|---|---|---|---|
| =
| }|||||
private static final String ROOT_KEY = "ROOT";
private static final String CHILD_ONE_KEY = "CHILD_ONE";
private static final String SUB_CHILD_ONE_KEY = "SUB_CHILD_ONE";
private static final String SUB_CHILD_TWO_KEY = "SUB_CHILD_TWO";
private static final String DUMMY_KEY = "DUMMY";
private static final String DUMMY_VALUE = "DUMMY"
<...>
public void doSomething() {
<...>
StringValueDTO dummy = new StringValueDTO();
dummy.setKey(DUMMY_KEY);
dummy.setValue(DUMMY_VALUE);
ComplexValueDTO subChildOne = new ComplexValueDTO();
subChildOne.setKey(SUB_CHILD_ONE_KEY);
subChildOne.getValue().add(dummy);
ComplexValueDTO subChildTwo = new ComplexValueDTO();
subChildTwo.setKey(SUB_CHILD_TWO_KEY);
subChildTwo.getValue().add(dummy);
ComplexValueDTO childOne = new ComplexValueDTO();
childOne.setKey(CHILD_ONE_KEY);
childOne.getValue().add(subChildOne);
childOne.getValue().add(subChildTwo);
ComplexValueDTO root = new ComplexValueDTO();
context.setKey(ROOT_KEY);
context.getValue().add(childOne);
<...>
}
<...>{code}

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