I did some investigation and the following is what happens. We would really
appreciate some explanation on why this is like this because it surely does
not look right to me.
The steps we used to simulate a weird scenario in apache CXF. We created a
class called TestService. The first example shows a generated wsdl from
this class which only have Java interfaces where the second example show an
example using concrete java classes. Apache CXF responds differently for
both implementations and the second leads to runtime issues.
1) Example without List implementation.
*import* javax.jws.WebMethod;
*import* javax.jws.WebService;
@WebService(name="TestService")
*public* *class* TestService {
@WebMethod
*public* *List* methodA(){
*return* *null*;
}
@WebMethod
*public* *List* methodB(){
*return* *null*;
}
}

The second example shows that when using ArrayList as the return type
apache cxf is creating complex types using JDK classes (arrayList,
abstractList abstractCollection). This is not desired in wsdl and it is
creating problems on the client side since it tries to generate this jdk
classes.
