CXF plugin - JAXB error

[msaucier]

Hi all, I am fairly new to Grails and CXF. I have a simple parent-child relationship and I want to expose some methods through SOAP-CXF using the Grails-CXF plugin.

I have the following 2 simple domain classes.

@XmlAccessorType(XmlAccessType.FIELD)
class Dealership {

static hasMany = [technicians:Technician]

String description

static constraints = {
description(blank: false , maxSize:100)
}
}

@XmlAccessorType(XmlAccessType.FIELD)
class Technician {

Dealership dealership
String firstName
String lastName

static constraints = {
firstName(blank: false , maxSize:100)
lastName(blank: false , maxSize:100)
}
}

and the following service class :

class DealershipManagementService {

static expose=[ 'cxf' ]

Dealership retrieveDealership(Integer id) {
return Dealership.get( id )
}
}

When I call the generated WebService retrieveDealership(1), I get the error :
Marshalling Error: A cycle is detected in the object graph. This will cause infinitely deep XML

Any help on how to fix this ?

Regards,

Martin

I suggest you do a web search for "CXF bidirectional relationship" or the same without "relationship". I found this link, which may help:

There is little documentation regarding Grails and CXF, what is the best and most used web services framework for contract last with Grails ? Metro, Axis2, just plain Jaxb annotations ? Thinking about switching to Metro and using the Grails plugin with JAX-WS annotations.

Any insight is appreciated.

You might want to ask on the Grails user mailing list. You'll have access to more people that use Grails and I know some use Grails with web services. I'm afraid I don't know which is the most used or best of the integrations, but I think the CXF plugin has been around for a while.
