How can I pass parameter from Apache CXF to Camel - web-services

Question

I am working currently on project where Apache CXF is integrated with Apache Camel. Apache CXF is a solution that we use to expose a WebService then marshal/unmarshal SOAP request and pass it to Camel. This is pretty standard. By default a POJO dataFormat in ApacheCXF is used however there is a need for getting some information form SOAP headers "" and pass it to Camel. My question is how to do this? When I use Interceptor in Apache CXF I can get information that I need but I cannot pass it then to Camel. The class below is a CXF Interceptor
public class MyInterceptor extends AbstractSoapInterceptor {
//..... some variables
#Override
public void handleMessage(SoapMessage message) throws Fault {
//..some logic and then setting a variable
message.getExchange().put("Foo", "Bar");
}
}
... and class below is Camel Processor that is eventually called:
public class MyCamelProcessor implements Processor {
#Override
public void process(Exchange exchange) throws Exception {
//how can I read information from CXF Intercptor here?
//how can I read "Foo" value?
}
}
I understand that Exchange class that is used by Apache CXF is different then Exchange used by Camel however there should be a way of passing information between these two integrated technologies?

Answer 1

Finally, I solved it how follow:
In my context, I have a consumer service with camel-cxf component which is routed to Processor.
CxfEndpoint class from Camel has a method call setInInterceptors:
public void setInInterceptors(List<org.apache.cxf.interceptor.Interceptor<? extends org.apache.cxf.message.Message>> interceptors)
Therefore, if we define the next in our beans definitions file:
...
<cxf:cxfEndpoint id="consumerId"
address="/myservice"
serviceClass="com.example.service.MyServiceSEI">
<cxf:inInterceptors>
<ref bean="myInterceptor"/>
</cxf:inInterceptors>
</cxf:cxfEndpoint>
<bean id="myInterceptor" class="com.example.interceptors.MyInterceptor" />
Then, in our custom Interceptor we can set any variable in a map
...
import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.binding.soap.interceptor.AbstractSoapInterceptor;
...
public class MyInterceptor extends AbstractSoapInterceptor {
public MyInterceptor() {
super(Phase.RECEIVE);
}
#Override
public void handleMessage(SoapMessage message) throws Fault {
//..some logic and then setting a variable
message.getExchange().put("Foo", "Bar");
}
}
Finally, we can get the variables in our Processor, using org.apache.cxf.message.Message class, different from org.apache.camel.Message used with Exchange.getIn() method
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.cxf.message.Message;
import org.apache.camel.component.cxf.common.message.CxfConstants;
public class MyCamelProcessor implements Processor {
#Override
public void process(Exchange exchange) throws Exception {
//how can I read information from CXF Intercptor here?
//how can I read "Foo" value?
Message cxfMessage = exchange.getIn().getHeader(CxfConstants.CAMEL_CXF_MESSAGE, Message.class);
String foo = (String) cxfMessage.getExchange().get("Foo");
// read message from camel context
org.apache.camel.Message inMessage = exchange.getIn();
...
}
}
