wsdl2java overwrites objectFactory methods if multiple service classes are in
the same package, causes value type inheritance problems
--------------------------------------------------------------------------------------------------------------------------------------
Key: CXF-1340
URL: https://issues.apache.org/jira/browse/CXF-1340
Project: CXF
Issue Type: Bug
Components: Tooling
Affects Versions: 2.0.3, 2.1
Environment: Windows XP, eclipse
Reporter: Incognito
If you have two wsdl-based services, who's wsdl2java output is in the same
package, the outputted objectFactory retains only the most recent service's
methods.
For example:
Given two wsdl files, CarService.wsdl and UserService.wsdl; if one executes the
wsdl2java binary with both services; with CarService first and UserService
second, and with both service classes being output in package org.example.api,
then only one objectFactory.java class will be created. First, objectFactory
will be created with the objects for CarService.wsdl, and then it will be
overwritten with UserService.wsdl's objects.
It just so happens that in this scenario, if the former service contains an
object that is abstract, that is, that it contains types that inherit via
wsdl's extension keyword, AND methods for creating instances of
CarService.wsdl's outputted java are NOT present in objectFactory.java, then
CXF does not include type information in the SOAP messages.
For example:
given an alternate CarService.wsdl with the following types:
<complexType name="Car" abstract="true">
...
</complexType>
<complexType name="Jeep">
<extension base="Car">
...
</extension>
</complexType>
If CarService.wsdl also had a method called getCarById, and wsdl2java output 2
java classes: getCarById.java and getCarByIdResponse.java, AND wsdl2java on
UserService.wsdl was executed AFTER it was executed on CarService (resulting in
an objectFactory without create methods for getCar*), then CXF will send SOAP
messages like the following
<soap>
<getCarByIdResponse> <!-- type information here would mistakenly be missing
-->
...
</getCarByIdResposne>
</soap>
The ultimate result is that if a project has more than 1 service being output
in the same package AND if more than 1 type in those two services use type
extension, then CXF will have problems marshalling those classes because it
will end up leaving out the type information for all classes not included in
the ObjectFactory. One alternative would be to have the wsdl2java classes be
output to multiple packages. If the different services shared types, this would
result in duplicated code in each service.
