[groovyWS] consuming a service
Locked

Hi!
I'm getting this error: Exception Message: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory I try to consume a soap service with groovyWS. I don't know where it comes from... The service is exposed with axis2 (in the same application). --------------------------------------------------- Error 500: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.cxf.wsdl.WSDLManager' defined in URL [jar:file:/home/jeremy/NetBeansProjects/backend/lib/groovyws-standalone-0.5.0.jar!/META-INF/cxf/cxf.fixml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.cxf.wsdl11.WSDLManagerImpl]: Constructor threw exception; nested exception is java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory Servlet: grails URI: /projetIBD/grails/livre/show.dispatch Exception Message: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.cxf.wsdl.WSDLManager' defined in URL [jar:file:/home/jeremy/NetBeansProjects/backend/lib/groovyws-standalone-0.5.0.jar!/META-INF/cxf/cxf.fixml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.cxf.wsdl11.WSDLManagerImpl]: Constructor threw exception; nested exception is java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory Class: LivreController At Line: [19] Code Snippet: 18: def proxy = getProxy() 19: proxy.initialize() 20: println "proxy configuré" --------------------------------------------------- Here's the exposed code: --------------------------------------------------- def Livre[] recherche (String titre, String auteur) { def listeDeLivre = Livre.findAllByTitreLikeAndAuteurLike("%"+titre+"%", "%"+auteur+"%") return listeDeLivre } --------------------------------------------------- and the action calling for it: --------------------------------------------------- def getProxy() { new WSClient("http://localhost:8080/projetIBD/services/livre?wsdl", this.class.classLoader) } def show = { println "Entrée dans Show Web Service" def proxy = getProxy() proxy.initialize() println "proxy configuré" def livreInstance = proxy.getLivre(params.id) println "Livre obtenu" if(!livreInstance) { flash.message = "Livre not found with id ${params.id}" redirect(action:list) } else { return [ livreInstance : livreInstance ] } } --------------------------------------------------- Do you have any clue as to its origin ? |

Hi
Can you consume this service for outside your application or do you get the same error ? Cheers Guillaume On Fri, May 8, 2009 at 9:32 AM, Toutanc <[hidden email]> wrote:

Hi!
Thx for your reply! I tested several things: 1/ soapUI Everything is working fine there. I can call my services without any problem 2/I copied the application and asked the second one to get the services from the first one. I get the same Exception as before (in the second "client-side" application) 3/I tried writing a small application using one domain class from my app and calling the web service. It seems to work ok but the data binding is not working: --------------------------------------------------- Show Livre Id: javax.xml.bind.JAXBElement@4611dca9 Titre: javax.xml.bind.JAXBElement@3eadff2f Auteur: javax.xml.bind.JAXBElement@114c86cf Ebook: javax.xml.bind.JAXBElement@372688e8 --------------------------------------------------- I used the same domain class with the call def livreInstance = proxy.getLivre(params.id) I also tried to bind the data with a variable: --------------------------------------------------- def livreInte = proxy.getLivre(params.id) def livreInstance = new Livre() livreInstance.properties=livreInte livreInstance.save() --------------------------------------------------- but all the fields were blank... Any clues?

Couple of points.
I would NOT use domain classes as your message containers. Yes, it's more work to create DTO's, but you will thank yourself one day. Trust me. How did you do your mappings? I am consuming a grails-based web service that has aegis mappings with groovyws and aegis is working fine. Anytime I see that "javax.xml.bind.JAXBElement@3eadff2f" stuff means I forget to map a property to a string. Feel free to review the mappings here: http://svn.codehaus.org/grails-plugins/grails-stitches/trunk/src/java/org/authsum/stitches/external/ HTH On May 8, 2009, at 12:59 PM, Toutanc wrote: > > Hi! > > Thx for your reply! > > I tested several things: > > 1/ soapUI > Everything is working fine there.

I followed that guide here: http://docs.codehaus.org/display/GROOVY/Using+the+Grails+XFire+plugin+and+GroovyWS
There did not seem to be any mapping to do... I put the result in the same class as the server (I copied the file fom the server app). I thought fields were mapped automatically. I can't find anything about mapping on the groovyWS page (apart from aegis). Thw for the tip about DTOs :) Toutanc

Bonjour

It should work. Cheers Guillaume On Sat, May 9, 2009 at 9:02 PM, Toutanc <[hidden email]> wrote:

Hi,
Did you manage to work out this issue? I have the same problem - I can consume a web service via groovyws ok, and I can expose a web service using xfire plugin. But when I use both in the same application I get the same error you do: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.cxf.wsdl.WSDLManager' defined in URL [jar:file:/home/myProject/lib/groovyws-standalone-0.5.0.jar!/META-INF/cxf/cxf.fixml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.cxf.wsdl11.WSDLManagerImpl]: Constructor threw exception; nested exception is java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory
