In Talend ESB 6.4.1, for dynamic purposes we use a DSLProcessor component to build a client CXF endpoint on the fly :
.toD("cxf://..." + "dataFormat=PAYLOAD" + "&wsdlURL=..." + "&serviceName=..." + "&endpointName=..." + "&username=..." + "&password=..." + "&headerFilterStrategy=#CXF_PAYLOAD_HEADER_FILTER" )
The call to the webservice itself works fine.
In the next component we try to get the WS soap response :
String response = exchange.getIn().getBody(String.class)
works fine when ran in Talend console (we can see the response code), but conversion of exchange body to String class fails with this error in Karaf :
javax.xml.transform.TransformerException: Can't transform a Source of type javax.xml.transform.stax.StAXSource
We tried many workarounds:
- insert a cConvertBodyTo --> String.class
- manage the response format with org.apache.camel.component.cxf.CxfPayload library then write it into a StringWriter --> same error
- manager the response format with javax.xml.transform.stax.StAXSource library, but the exchange body cannot be casted to this (very strange, given the error above)
We need a solution to get the response.
We have redirected your issue to our ESB experts and then come back to you as soon as we can.
Many thanks for your time.
You may try to resolve this issue following
Option 1), adding the "&allowStreaming=true" to your DSL CXF endpoint, I don't remember exactly the default value is true or false in Camel cxf component, but you can swith true/false to testing
Option 2), set back the String to the body after you getBody(String.class), like this: exchange.getIn().setBody(response);
Let us see if it will woks. (it works in Studio run maybe the Studio has not camel-cache dependency added by default)
Didn't mentionned it in my first post, but unfortunatly we already tried true and false for streaming parameter, none works.
About 2nd option, it is not possible as we run into an exception from "getBody(String.class)".
