After many, many, too many attempts, finally I have understood how to expose external webservice, that is how to proxy one or more webservices (wsdl included). (servicemix.xml file is attached)
Suppose I have two webservice to proxy at urls http://pc-webservice:8080/axis/services/AxisWebservice http://pc-webservice2:8080/xfire/services/XFireWebservice 1) I have to connect the wsdl and the remote webservices to the endpoints (providers) <http:endpoint service="ns1:AxisWebservice" endpoint="axisWebserviceEP" targetService="ns1:AxisWebservice" role="provider" locationURI="http://pc-webservice:8080/axis/services/AxisWebservice"; wsdlResource="http://pc-webservice:8080/axis/services/AxisWebservice?wsdl"; /> <http:endpoint service="ns2:XFireWebservice" endpoint="xfireWebserviceEP" targetService="ns2:XFireWebservice" role="provider" locationURI="http://pc-webservice2:8080/xfire/services/XFireWebservice"; wsdlResource="http://pc-webservice2:8080/xfire/services/XFireWebservice?wsdl"; /> 1) I have to make a connector for riceiving requests form clients (consumers). I used http-component to make this: <http:endpoint service="ns1:AxisWebservice" endpoint="axisWebserviceEP" targetService="myns:routerForAxis" role="consumer" soap="true" targetInterfaceName="ns1:AxisWebservicePortType" locationURI="http://localhost:8080/services/AxisService/"; defaultMep="http://www.w3.org/2004/08/wsdl/in-out"; /> <http:endpoint service="ns2:XFireWebservice" endpoint="xfireWebserviceEP" targetService="myns:routerForXFire" role="consumer" soap="true" targetInterfaceName="ns1:XFireWebserviceSEI" locationURI="http://172.30.10.183:8888/services/XFireService/"; defaultMep="http://www.w3.org/2004/08/wsdl/in-out"; /> 3) I have to create an invoker for the webservice <sm:activationSpec componentName="axisServiceComponent" service="myns:targetForAxis" endpoint="axisService"> <sm:component> <bean class="org.apache.servicemix.components.saaj.SaajBinding"> <property name="soapAction" value="" /> <property name="soapEndpoint"> <bean class="javax.xml.messaging.URLEndpoint"> <constructor-arg value="http://pc-webservice:8080/axis/services/AxisWebservice"; /> </bean> </property> </bean> </sm:component> </sm:activationSpec> <sm:activationSpec componentName="xfireServiceComponent" service="myns:targetForXFire" endpoint="xfireService"> <sm:component> <bean class="org.apache.servicemix.components.saaj.SaajBinding"> <property name="soapAction" value="" /> <property name="soapEndpoint"> <bean class="javax.xml.messaging.URLEndpoint"> <constructor-arg value="http://pc-webservice2:8080/xfire/services/XFireWebservice"; /> </bean> </property> </bean> </sm:component> </sm:activationSpec> 4) Now let's create a service for redirecting the request, for example the wireTrap router. <sm:activationSpec componentName="wireTrapAxis"> <sm:component> <eip:component> <eip:endpoints> <eip:wire-tap endpoint="wireTrapAxisEndpoint" service="myns:axisWireTrap"> <eip:target> <eip:exchange-target service="myns:targetForAxis" /> </eip:target> <eip:outListener> <eip:exchange-target service="myns:trace" /> </eip:outListener> </eip:wire-tap> </eip:endpoints> </eip:component> </sm:component> </sm:activationSpec> <sm:activationSpec componentName="wireTrapXFire"> <sm:component> <eip:component> <eip:endpoints> <eip:wire-tap endpoint="wireTrapXFireEndpoint" service="myns:xfireWireTrap"> <eip:target> <eip:exchange-target service="myns:targetForXFire" /> </eip:target> <eip:outListener> <eip:exchange-target service="myns:trace" /> </eip:outListener> </eip:wire-tap> </eip:endpoints> </eip:component> </sm:component> </sm:activationSpec> The myns:trace service is simply a logger components that log messages 5) The chain is finished now we have the two external webservices exposed at urls http://localhost:8080/services/AxisService/ http://localhost:8080/services/XFireService/ and their wsdl http://localhost:8080/services/AxisService?wsdl http://localhost:8080/services/XFireService?wsdl 6) complete listing of servicemix.xml and some explanation <!-- Namespaces of the webservices wsdl must match the local namespaces of the servicemix local services.
