Elements and parts seem to default to "return" - which upsets WSDL2X as "return" is generally a reserved word
Hi,
I'm new to CXF, so forgive this newb question. For almost all simple
web services that I create using Java, such as those described here:
http://cwiki.apache.org/CXF20DOC/a-simple-jax-ws-service.html
I get parts or elements automatically named "return" in the resulting
auto-generated WSDL (see example below).
As you'll see below, the argument is given a nice name like "arg0",
but the return is called "return". Unfortunately, return is a
reserved keyword in many languages, so this forces many
WSDL2LanguageX converters to rename.
Can you change the default return name for elements/parts to
something like "return0" ? Right now, I can't use CXF web services
from salesforce.com without hacking all my WSDL files (or, when I
have access to source, adding an annotation).
LMK if I've got this wrong!
Thanks!
Jon

Hi Jon,
Do you mind send us the complete wsdl, we do have the "return" element
in our test, so this case should be covered already.
Or you can log an issue in jira and attach your wsdl
BTW, which CXF version are you using?
Thanks,
James

Hi Jervis/James,
You hit the nail on the head with the Spec section. I still wish
they didn't choose a reserved word when they wrote the spec... As you
say Jervice, the name shouldn't be relevant, but unfortunately using
"return" means that anyone writing a WSDL2X will need to take more
care.
The situation I have is that I have a number of local web services
(created using CXF + annotated POJO) that I'm feeding to
Salesforce.com. Salesforce.com can consume arbitrary SOAP services -
it takes the WSDL and creates local "Apex" objects which then do all
the dirty work. The problem is that is nobody has control over that
process (it's hosted). I have to currently edit the WSDL before
this happens, otherwise the Apex objects are invalid. (or use
@WebResult)
I'll be reporting this to them though, and pointing out the spec -
hopefully they can change their mapper to take more care in assigning
names :-)
Thanks for the resolution. I'm having great fun with CXF - it's
remarkably easy to get a SOAP service up and running now.
Regards,
Jon

RE: Elements and parts seem to default to "return" - which upsets WSDL2X as "return" is generally a reserved word

One thing to add. If your WSDL is doc-lit wrapped (this type of WSDL is generated by java2wsdl by default unless your java class has annotations to customize this), a Response Bean is required to be generated by WSDL2JAVA tool. In this case, the WSDL2JAVA tool is also required to resolve any name collisions in response bean. In CXF, when JAXB is the databinding used by WSDL2JAVA, the name mapping is handled by JAXB, detailed can be found in JAXB 2.0 spec Appendix D "BINDING XML NAMES TO JAVA IDENTIFIERS".

RE: Elements and parts seem to default to "return" - which upsets WSDL2X as "return" is generally a reserved word
Posted by "Liu, Jervis" <jl...@iona.com>.
Jon, the mapping name of "return" is per JAX-WS 2.0 spec. Section 3.6.1:
"Conformance (Result naming): The javax.jws.WebResult annotation (see 7.10.4) MAY be used to
specify the name of the wsdl:part or XML Schema element declaration corresponding to the Java method
return type. If both the name and partName elements are used in the javax.jws.WebResult annota-
tions then the partName MUST be used for the wsdl:part name attribute and the name elment from the
annotation will be ignored. In the absence of customizations, the default name is return."
As far as the WSDL2JAVA tool is concerned, the return name is not significant as it is not needed by the language, only the return type is significant. Or you have specific WSDL2Language in your mind?
