Using xmlBeans

[ma_crice]

Has anyone got a good example of this. I have a webservice that extended the AbstractDomPayloadEndpoint, this works just lovely, but I want to take away the code for recieving and responding, and replace it with xmlBean mapping. I thought this would be as simple as changing my endpoint to extend the AbstractMarchallingPayloadEndpoint, setting up the xmlBean marshaller and unmarshaller in the spring config, and then wiring them to my endpoint. unfortunately I get the following message:

java.lang.IllegalStateException: No adapter for endpoint [uk.org.rspca.ws.cms.TaxonomyEndpoint@165b7e]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint?

little confused at this point, do I need to write an adapter for this approach to work?

Any help would be apprieciated...

It should be as simple as extending AbstractMarchallingPayloadEndpoint, so I have no idea what is going wrong. Can you post the code of your endpoint class?

Hi Arjen,

Thanx for the reply. I have recently taken part in A Spring Web Service Taining course run by Russ Miles, which was really worth while, but didn't cover this specific topic. Your help is much apprieciated.

I don't see anything wrong with the code you posted. Could you also post the log contents at DEBUG level, including startup messages? That shows me what endpoints are supported and which aren't.

Last but not least.... the log file contents with root log level set to DEBUG is atatched.

Note: the logging output is the result of a WSDL discovery, and a call to the animalTaxonomy Service.

Any update for me Arjen

[olivern]

Should reference 'ref=taxonomy' in your spring config file be 'ref=animalTaxonomy' ?

[ma_crice]

What I have is correct. There is a spring config file which sets up service objects that was not included in what I posted.

Thanx for at least replying though - I still haven't had much luck with this! Have yuo used the xmlBean marshalling?

[olivern]

Yup - I use XmlBeans - It worked for me pretty much out of the box....

I don't see any obvious issues with your configuration either

[ma_crice]

I don't supose you have that example handy, and that I could have a look and compare it to mine? Would be really useful...
