Mixing document and RPC styles

[socialguy]

I'm wondering if document and RPC styles can both be used for an endpoint? The WSDL allows you to configure it for each operation using <soap:operation style="rpc" />, so it looks theoretically possible, but wsimport complains that

Ignoring port "Calculator", its not WS-I BP 1.1 compliant: the wsdl binding has mixed style, it must be rpc-literal or document-literal operation. try running wsimport with -extension switch.

No that is not possible.

The restriction comes from JAX-WS 2.2:

The javax.jws.SOAPBinding annotation MAY be used to specify at the type level which style to use for all methods it contains or on a per method basis if the style is document.

and JSR-181:

The annotation may be placed on a method if and only if the SOAPBinding.style is DOCUMENT. Implementations MUST report an error if the SOAPBinding annotation is placed on a method with a SOAPBinding.style of RPC. Methods that do not have a SOAPBinding annotation accept the SOAPBinding behavior defined on the type.

So in your case when you start from WSDL-to-Java, the following rule (Conformance (Using javax.jws.SOAPBinding)) applies:

An SEI mapped from a port type that is bound using the WSDL SOAP binding MUST be annotated with a javax.jws.SOAPBinding annotation describing the choice of style, encoding and parameter style. The annotation MAY be omitted if all its properties would have the default values (i.e. document/literal/wrapped).

JAX-WS cannot generate a SEI that does not follow the rules of JSR-181 and will generate an error.

Basic Profile v1.1 has been explicit in this case:

The style, "document" or "rpc", of an interaction is specified at the wsdl:operation level, permitting wsdl:bindings whose wsdl:operations have different styles. This has led to interoperability problems.

R2705 A wsdl:binding in a DESCRIPTION MUST either be a rpc-literal binding or a document-literal binding.

Thank you. I'm glad to have asked the first question in this forum
