Overloaded methods - XFire->CXF with Aegis
I have a WebService class that has a pair of overloaded methods.
One has two parameters - an object reference and a long value, returning an
array of objects. The other adds a third parameter, a String.
I'm using Spring and jaxws:endpoint tags to load the service, per many of
the examples on the CXF site, and most of this stuff works, but it appears
to be complaining about overloaded methods when I fire up Tomcat:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'TradingPartnershipService': Invocation of init method failed;
nested exception is java.lang.IllegalArgumentException: An operation with
name [{http://ws.catalog.inovis.com}getRetailersWithAccess] already exists
in this service
Caused by:
java.lang.IllegalArgumentException: An operation with name
[{http://ws.catalog.inovis.com}getRetailersWithAccess] already exists in
this service
at
org.apache.cxf.service.model.InterfaceInfo.addOperation(InterfaceInfo.java:71)
at
org.apache.cxf.service.factory.ReflectionServiceFactoryBean.createOperation(ReflectionServiceFactoryBean.java:454)
My interface defines these as follows:
public RetailerAccess[] getRetailersWithAccess(
@WebParam(name = "UserIdentifier", targetNamespace =
TNS)UserIdentifier userId,
@WebParam(name = "vendorAccountNumber", targetNamespace =
TNS)long vendorAccountId
);
public RetailerAccess[] getRetailersWithAccess(
@WebParam(name = "UserIdentifier", targetNamespace =
TNS)UserIdentifier userId,
@WebParam(name = "vendorAccountNumber", targetNamespace =
TNS)long vendorAccountId,
@WebParam(name = "selcode", targetNamespace = TNS)String selcode
) throws WebServiceException;
Is there some additional configuration I can do for CXF to handle these
overloads correctly? Or should I plan to rename one of them?
Thanks in advance.

The main reason is that CXF is really trying to hard to be WSI-BP
compliant as much as possible. By doing so, it should ensure that
webservices deployed with CXF should be interoperable with other WSI-BP
compatible toolkits.
On of the things that the WSI-BP explicitly forbits is operation
overloading in the wsdl. As soon as that occurs, you WILL end up with
interoperability issues as lots of toolkits don't support it.

I'm still trying to figure this out; it's easy enough to change method
names, since they're not customer-enabled (yet, anyway). But I'd like
to better understand why CXF complained when XFire didn't.
Until more-recently, I/we just went with sample code and took the
technology layout for granted. But now with this CXF migration, I'm
being forced to take a closer look at the stack composition to
understand how these technologies interrelate in the WS stack.
If anyone knows a good top-level map of such things on the web, feel
free to share. :)

Specifically, I believe you can not have to methods mapped to the
same operation name in JaxWS, but you can change the operation name
of one of the methods using the @WebMethod annotation (see the
example in the linked example [1]).
Unfortunately, there doesn't seem to be any equivalent xml (or
annotation for aegis). Is this something XFire supports and CXF
doesn't?

I don't believe you can do that with web services[1]--JAX-WS doesn't
support overloaded methods.
