The component's implementation provides the business logic
for the service.
About this task
The icon in the component indicates its implementation type.
If the component's implementation does not exist, there is an exclamation
mark in the lower left corner of the component. The following CustomerQuery
component does not have an existing business process implementation:
There is no exclamation mark on the component when
its implementation exists. The following CustomerQuery component has
an existing business process implementation:
To create the implementation for a component, follow these
instructions:
Procedure
- In the assembly editor, click the component so that it
is selected.
- Right-click the component and select Generate
Implementation to create the implementation. If a new
implementation is generated then it will be opened for editing. If
there is no implementation type for the component, you have to select
a type for this action.
To use an existing implementation
for the component, click Select Implementation and
select one of the listed implementations. Note that the listed implementations
are located within the same module. Implementations in other modules
can be used in the module assembly by creating imports for the published
services (exports).
Note: The
Select implementation action
does
not add or remove component interfaces or partner references
so that it does not affect existing wires. However, after using this
action, the component's existing interfaces or references might
not match
what is required by the selected implementation. In this case, there
will be errors in the assembly diagram. Try these actions to fix the
errors:
- Use the Synchronize Interfaces and References menu
item on the component to synchronize to or from the implementation.
See "Synchronizing the interfaces and references between components
and implementations" in the related links at the end of this topic.
- Manually add the required interfaces and references to the component,
and remove or change the non-matching ones.
- Drag the implementation onto the canvas (to create a new component)
and then rewire the assembly diagram so that the new component replaces
the unimplemented component. Be sure to also copy the name and qualifiers
you defined in the original component to the new one. Afterward, you
can safely delete the replaced component.
If interfaces or partner references have been replaced, you may
need to add interface maps to rewire.
