I have been looking at the JAX-WS and JAXB specs and I think it
should be possible to pass nulls when using the default Java to
XML mapping. Can you open a JIRA and attach a test case that
shows the problem you are having with this?

Simon,
Yes, it requires the removal of overloaded methods and I also have to change
any java objects to be in a javabean format. Although, this would have to be
done either way. Our system had some code which was not conformed to
javabean style and since we are now converting to use Tuscany, it must be
updated for the java object creation by tuscany. I had thought that the
non-void return type was an issue, but I tried the sample mentioned in the
previous response and think it should work just fine.
There is also a different issue that I have discovered and was going to post
about, but I was trying to check the old mailing lists first. I did not find
it mentioned there. It seems that the the Transformer classes for converting
to and from XML for both simple and javabean styled objects does not handle
the inclusion of null values. This includes both passing in a null as a
parameter or returning null from a method. Is this a desired/required
situation that nulls can not be used? or is it a flaw in the conversion. The
one exception where null values do process correctly are null Strings. If
this is a requirement, then I would also have to change logic in my system
to work around not being able to use null values. This may be problematic.
Thanks, Bentley

Bentley,
What modifications are needed to your code to make it conform to the
doc/lit/wrapped standard? Is this just the removal of overloaded
nethod names, or something else?

Hello, thanks for the response and input.
One thing I realized was that I didn't make clear in my original post was
that I am working with the distributed domain/node system which seems to
use
only the SCA binding by default with the Remotable annotation. This does
not
allow me to use the WSDL configurations. This assumption is based on the
sample distributed code and testing I have attempted.
Using the default SCA binding of that configuration seems to always use
the
wrapper (document/literal) mode. This is not a large issue, as my code can
be modified to conform to its standards. If there is some other way to
have
the services register within the domain that I have not seen, that
information would be appreciated.
Thanks
Bentley

It certainly use doc/lit/wrapped by default and WSDL generated by Tuscany
Java2WSDL will use this style. The SCA WebService spec says that, when

anything that is valid in the WSDL binding. I can't guarantee that this

style. This is being set within the
org.apache.tuscany.sca.binding.ws.axis2.Java2WSDLHelper class in the
createWSDLInterfaceContract method. From my understanding, this implies
that
all methods in the service must have a return type that is not void and

You should be able to have a void return type. There is an itest that
shows
an example (
http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/itest/ws-void-args-return/
[http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/itest/ws-void-args-return/]

[http://svn.apache.org/repos/asf/incubator/tuscany/java/sca/itest/ws-void-args-return/]]
)
overloaded methods are not allowed.
Do you mean WSDL operations with the same name but with different
parameters?
Is there a way to set it to not use the wrapper style or is it just the
standard that is used by the SCA binding and must be followed?
I think the intention is that any web services communications that go on
under Tuscany's control, e.g. where the remote version of the SCA binding
is
in use, choose the doc/lit/wrapped style and stick with that. If
alternative
styles are required then this would be configured using a
separately/manually authored WSDL to describe what style is required. I
would imagine this would very likely to be the case if SCA is configured
to
talk to web services that are provided by other, non-SCA, systems. Here
you
would expect to be able to get the WSDL from the service provided. Do you
have a scenario that requires the use of something other than the
doc/lit/wrapped style in the case that one SCA component is talking to
another SCA component with the same domain?
Thanks
