Hi,
I'm having a very similar problem as described here:
http://marc.theaimsgroup.com/?l=axis-user&m=113819830006177&w=2
My schema is included below.
I'm trying to implement a composite pattern. There are three types derived
from an abstract type as follows:
Workflow (abstract)
/ | \
Parallel Sequence Pipeline
Both parallel and sequence elements must contain nested Workflow elements
(one or more of parallel, sequence or pipeline), whereas pipeline elements
cannot - they form the leaves of the workflow tree.
An example of a document would be:
<perform>
<sequence>
<parallel>
<pipeline> ... </pipeline>
<pipeline> ... </pipeline>
</parallel>
<pipeline> ... </pipeline>
</sequence>
<perform>
In the schema I've defined an abstract Workflow element and elements
parallel, sequence and pipeline. These are substitution elements for the
Workflow element.
When I generate Java beans with WSDL2Java there is no trace of the
parallel and sequence elements. There is a Java class called Composite
which extends WorkflowComponent but there is no way of telling whether
this Composite object used to be a sequence or a parallel element. How can
I force Axis to generate Java beans corresponding to those elements?
Any help with this would be appreciated.
Thanks,
Amy
