Plugin conflicts with grails-cxf?

[JonNeat]

Hi all,

We try to use both grails-cxf-client for endpoints and grails-cxf for exposing simple services.

They both work independently (only configurating one), but not together - why? No error messages are thrown, nothing what so ever.

We are running with grails 2.3.0RC1. Everything newest version.:
runtime ":cxf:1.1.1"
compile ":cxf-client:1.5.6"

Can anyone help? What are we doing wrong? We even tried a whole new "hello world"-grails project, and still doesn't work.

Jon.

tested with grails 2.2.1 and https://github.com/Grails-Plugin-Consortium/grails-cxf-client-demo and they work fine together. Trying 2.3.0 now with that project.

The demo project also works find with grails 2.3.0. You can clone that here. https://github.com/Grails-Plugin-Consortium/grails-cxf-client-demo/tree/grails-2.3.0

I will need more info to help debug. It could be in your config or some other conflicting plugins??

(I'm working on the same project as the OP)
I traced the problem: it only occurs when a service (or one of the classes it references) references a bean that was created by the cxf-client plugin, i.e.

@GrailsCxfEndpoint(expose=EndpointType.SIMPLE)
class MyService {
...
}

works fine.

@GrailsCxfEndpoint(expose=EndpointType.SIMPLE)
class MyService {
  def endpointBeanWasSetupByCxfClientPluginInConfigDotGroovy
...
}

does not.

I am not sure I ever tested this. I would guess it has to do with the order of bean wiring or the cxf proxy class.

Can you wrap the cxf client in a grails service and call the FooService class that will in turn call the endpointbean class?

[TobiasMahlmann]

Hi ctoestreich,
I hope I got you right:

class FooService{
    def cxfClientEndpoint
    public String someMethod(){
       ...
    }
}

@GrailsCxfEndpoint(expose=EndpointType.SIMPLE)
class MyService {
    def fooService

    public String exposedMethod(){
      return fooService.someMethod()
   }
}

This is actually our setup, but unfortunately doesn't work. It did however work with grails 1.3.7
Would it make sense to try to not use the cxf-client plugin and write the cxf XML file ourselves?

[TobiasMahlmann]

I found a workaround for the problem:

cxf{
    client {
        targetServiceEndpoint {
           ...
        }
}

@GrailsCxfEndpoint(expose=EndpointType.SIMPLE)
class MyService{
   def grailsApplication
   MyEndpoint myEndpoint

   private MyEndpoint getEndpoint(){
        if(myEndpoint==null){
           myEndpoint = grailsApplication.getMainContext().getBean("targetServiceEndpoint")
        }
       return myEndpoint
    }

    public String exposedMethod(){
      return getEndpoint().someMethod()
   }
}

Not pretty, but works. I don't know enough about the Spring internals to make a prettier solution though.

Had a similar problem. I have a cxf service that works fine when using cxf plugin alone. In that application i also need to consume an external service. After i add cxf-client and generate the stubs using wsdl2java, i get no service found error when trying to list services. Saw similar errors, one suggested modifying the cxf-client plugin WebServiceClientFactoryImpl class.

Bus bus = Holders.grailsApplication.mainContext.getBean("cxf") as Bus
JaxWsProxyFactoryBean clientProxyFactory = new JaxWsProxyFactoryBean(serviceClass: serviceInterface,address: serviceEndpointAddress, bus: bus)

(http://stackoverflow.com/questions/26470223/cant-get-cxf-and-cxf-client-to-work-at-the-same-time-grails). I tried with no luck. Grails version 2.4.5 and cxf client version 2.1.1
