Apply XSLT transforrmation after a CXF Enpoint fails
Hi,
I want
- expose a CXF endpoint "from" via a CXF servlet ==> OK, it works
- apply a XSLT transformation on the SOAP envelope of a multipart SOAP
message
retreived via the CXF servlet ==> KO
- resend the modified SOAP message via a Web service client
so , I built a route like this :
<cxf:cxfEndpoint id="soapMessageEndpointProvider"
serviceClass="....MyCxfProvider"
address="..."
wsdlURL="..."
endpointName="s:..."
serviceName="s:..."
xmlns:s="..."/>
<cxf:cxfEndpoint id="soapMessageEndpointProducer"
serviceClass="????"
address="http://localhost:9000/MyFinalServiceProvider/SOAPMessageService"
wsdlURL="..."
endpointName="s:..."
serviceName="s:..."
xmlns:s="..."/>
<camelContext id="camel-context" trace="true"
xmlns="http://activemq.apache.org/camel/schema/spring">
<route>
<from uri="cxf:bean:soapMessageEndpointProvider"/>
<to uri="xslt:file:///c:/mySheet.xsl"/>
<to ref="cxf:bean:soapMessageEndpointProducer" />
<route>
</camelContext>
I successfully retreive my message as an instance of SOAPMessage object
But I have 2 issues:
1: When I add the xslt processor above, I have an error:
"org.apache.camel.NoTypeConversionAvailableException :
No type converter available to convert
from type: class org.apache.camel.component.cxf.CxfMessage
to the required type: javax.xml.transform.Source
...."
So I tried to implement my own XSLT processor.
I get the SOAP envelope / SOAP PAYLOAD with:
SOAPMessage soapMessage =
(SOAPMessage)inMessage.getBody(List.class).get(0);
SOAPPart sp = soapMessage.getSOAPPart();
SOAPEnvelope se = sp.getEnvelope();
SOAPBody sb = se.getBody();
And I would like to do :
XSLT
SOAPEnvelope ==> envelope(XML) ======> transformed envelope(XML) ==>
SOAP envelope
In that case, my problems are :
- how to retreive the XML of my SOAPEnvelope
(My soap message is a multipart message so I cannot apply the XSLT
transformation on the whole http request)
- how to re transform my envelop XML in a SOAPEnvelope to continue the
processing as if the XSLT transforamtion did never occur
I know it is probably at the frontier between CAMEL, CXF, JAX-WS and Jaxb
but if you have an idea, it would be very helpfull for me.
2/ my second proble is about the WS endpoint producer
With WS consumer Endpoint, it is possible to avoid the use with classes
generated by wsdl2java
In that case, we use a fake Web Service Provider class (like described in
http://activemq.apache.org/camel/cxf-example.html)
For Producer Endpoints (WS client), in mode MESSAGE, is it possible to do
the same thing. Iwant to say, is it possible to avoid to add in the
classpath the classes generated by wsdl2java).
Thanks.
Guillaume

Hi,
I think the solution is depending on your requirement.
Can you give me more detail information about your soap message?
If this multipart SOAP message has some attachments, you can use the
SOAP handler to handle this attached message, let CXF unmarshal the
SOAPEnvelope message, then you can do what you want on the request
parameters, then marshal the request according to your target service.
If there is not much change of SOAPEnvelope for the XSLT transformation
part, I think you can turn the SOAP message into a String then use
String's replace method to change it :)
For the question of WS endpoint producer.
Current CXF doesn't support to call the JAXWS dispatch API(CAMEL-382),
you still need to specify the SEI for setting CXFEndpoint.
If you already make up a whole stream soap message, you can use the
camel-http producer to send the request, but I don't know how can handle
the soap response.
