Exposing a web service

manta7 Mar 29, 2011 5:44 AM

Hello,

I know this is a common problem but i didn't find the solution on this problem..

I have create a web service with axis2/tomcat on this address: http://localhost:8080/axis2/services/HelloService2?wsdl

And I would like to expose it through my ESB (for a centralized exposition of all my services).

So I have create a SA project, and a servicemix-cxf-bc. Into the BC directory I have put my WSDL and I configured my xbean like that :

<beans xmlns:cxfbc="http://servicemix.apache.org/cxfbc/1.0"

xmlns:HelloService2="http://hello.registry.test">

<cxfbc:consumer wsdl="classpath:HelloService2.wsdl"

targetService="HelloService2:HelloService2"

targetInterface="HelloService2:HelloService2PortType"/>

</beans>

I thought it was the good solution but when I'm trying to reach my tomcat address (http://localhost:8080), it's replaced by Apache CFX that list my "known services" which contains my HelloService2. Also when I'm trying to make a soap request on this service, it necessarily don't works.

So ok, it's not the good solution, but do I have to write a cxfbc:provider tag on my xbean also ? I don't think so cause I just want to expose an external service, external in the sense of providing by an another system (Axis 2) but on the same machine.

Need help !

Hi,

You do need a cxfbc:provider in this case.

The workflow is

external client ====>cxfbc:consumer====> cxfbc:provider====>external service(axis server in your case)

cxfbc:consumer will start a listening port and play the server side role, cxf bc:provider play the client side role.

Here cxfbc:consumer====> cxfbc:provider just like a bridge, we actually have a testcase[1] which can demonstrate how this bridge works.

Btw, you need ensure your axis server not use rpc/encoded style as that style is quite old and not supported by cxf.

Ok ok, thanks for the answer! I understand..

I wrote that:

<beans xmlns:cxfbc="http://servicemix.apache.org/cxfbc/1.0"
       xmlns:HelloService2="http://hello.registry.test">

    <cxfbc:consumer wsdl="classpath:HelloService2.wsdl"
                      targetService="HelloService2:HelloService2"
                      targetInterface="HelloService2:HelloService2PortType"/>
+                         +
+     <cxfbc:provider wsdl="classpath:HelloService2.wsdl"+
                      locationURI="http://localhost:8092/HelloService2"
                      service="HelloService2:HelloService2"
                      endpoint="HelloService2PortProxy"
                      interfaceName="HelloService2:HelloService2PortType"/>

</beans>

With a consumer and a provider. But I still have a problem.

You said "cxfbc:consumer will start a listening port", indeed, when I'm going on http://localhost:8080 I fall on CFX (no more on Tomcat), as if it erase my previous listening port. So how can I change the listening port of my consumer ?

Hi,

In cxfbc:consumer, you can specify locationURI using any port you want, this is the webservice url you exposed for external client.
And in cxfbc:provider, you can specify another locationURI which should be the same as the one used for your axis server, so that cxfbc:provider can talk to your server.

Great, it works!

We can find more information here: http://servicemix.apache.org/servicemix-cxf-bc.html
