Hi, Am hoping someone can give me a hand with a potential issue (or a misunderstanding on my part) with java2ws with respect to the target namespaces being generated for the operation message types.
Some background: We have a requirement to move roughly 15 web services from "Code-First" to "Contract-First". In addition, we now need to collapse these 15 web services into 1 big WSDL (not my choice). To date we have been using java2ws via the cxf-java2ws-plugin (2.3.1) to generate the WSDL for each of our services. Now, to boil this (potential) issue (or misunderstanding) down to a small size, let say we have 2 existing Web Services and that we need collapse into 1 WSDL and then move away from Code-First. Here are there definitions: package com.foo; @WebService(targetNamespace="http://com.foo";) public interface FooService { @WebMethod @WebResult(targetNamespace="http://com.foo";) String myFooMethod(String x); } package com.bar; @WebService(targetNamespace="http://com.bar";) public interface BarService { @WebMethod @WebResult(targetNamespace="http://com.bar";) String myBarMethod(String x); } After running java2ws on these 2 services, we see that the targetNamespace for elements and complexTypes "myBarMethod" and "myBarResponse" are " http://com.bar";, which is expected (some attributes and other elements removed for clarity): <xs:schema xmlns:tns="http://com.bar"; targetNamespace="http://com.bar"; version="1.0"> <xs:element name="myBarMethod" type="tns:myBarMethod"/> <xs:element name="myBarMethodResponse" type="tns:myBarMethodResponse"/> <xs:complexType name="myBarMethod"> <xs:sequence> <xs:element minOccurs="0" name="arg0" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:schema> Now, our solution to merge all of these services into one WSDL was to initially generate the WSDL using java2ws and then migrate our infrastructure away from java2ws to start using wsdl2java. The following solution seemed to be the most efficient to get us there. We would basically create a temporary UberService interface that extended FooService and BarService like so to generate the 1 big WSDL package com; @WebService public interface UberService extends FooService , BarService { } We then process UberService via java2ws and a UberService.wsdl is generated and all methods from each service are merged into one WSDL, exactly what we wanted. However, we did notice that element/complexType "myBarMethod" , "myBarMethodResponse" , "myFooMethod" and "myFooMethodResponse" are now in the "http://com"; namespace instead of the expected http://com.bar and http://com.foo namespaces respectively The 3 WSDL's are attached.... It seems like java2ws in this situation (processing an interface that extends other interfaces annotated with @WebService) is ignoring the targetNamespace that is defined for both FooService and BarService. There may be a good reason for doing this (specifications, etc) but am not sure if it is a bug or a feature or PEBKAC :) Anyone have any thoughts? Al
