Re: JAXRS How to define/use Multiparts with Json + xs:base64Binary

[J. Fiala]

Sergey,

Do you maybe have any example of a WADL including such multiparts which 
do not only generate as MultipartBody?

Best regards,
Johannes

WADL is currently underspecified with respect to handling complex 
multiparts, that is why MultipartBody is generated. In some simple 
cases @Multipart parameters can be generated to repesent simple 
multiparts, or have InputStream as a parameter

p.s. a basic multipart like

<representation mediaType="multipart/form-data" />

works, but then I only get the generic MultipartBody generated without
any hint to the client how to assemble it correctly.

Hello,

I defined a Multipart in the WADL (I'd like to use a multipart with
both json data + binary data):

<resource path="/createMultipart">
                <method name="POST">
                    <request>
                        <param name="name" style="query"
type="xs:string" required="true"/>
                        <representation mediaType="application/json"
element="mytypes:CreateMultipartRequestType"/>
                    </request>
                    <response status="200">
                        <representation mediaType="application/json"
element="xs:string"/>
                    </response>
                </method>
            </resource>

<xs:complexType name="CreateMultipartRequestType">
        <xs:sequence>
            <xs:element name="requestModel"
type="mytypes:CreateRequestType" />
            <xs:element name="payload" type="xs:base64Binary"
xmime:expectedContentTypes="application/octet-stream"/>
        </xs:sequence>
    </xs:complexType>

<xs:complexType name="CreateRequestType">
        <xs:sequence>
            <xs:element minOccurs="1" name="description"
type="xs:string" />
</xs:sequence>

</xs:complexType>

The generated Java code looks fine:

@POST
    @Consumes("application/json")
    @Produces({"application/json" })
    @Path("/createMultipart")
    String postCreateMultipart(@QueryParam("name") String name,
CreateRequestType createRequestType);

public class CreateMultipartRequestType {

    @XmlElement(required = true)
    @NotNull
    @Valid
    protected CreateRequestType requestModel;
    @XmlElement(required = true)
    @XmlMimeType("application/octet-stream")
    @NotNull
    protected DataHandler payload;

}

However, when I try to invoke the service using JacksonProvider, I get:

WARNING: Interceptor for {http://myns/}MyResource has thrown
exception, unwinding now
org.apache.cxf.interceptor.Fault: No message body writer has been
found for class at.hello.CreateMultipartRequestType, ContentType:
application/json

Any idea how I have to specify the Multipart in the WADL to get it
working?

Best regards,
Johannes
