Re: XmlSchemaComplexType exception

Thu, 24 May 2007 01:26:25 -0700 

Hi Tog,
Class defined as method input para need @XmlRootElement now. Besides the GetBook.java, I also remove @XmlRootElement from Book.java, which is input para for addBook method, I also get the same exception, would you please verify it? 


The reason is in CXF URIParameterInInterceptor.java, we check input 
paras (MessagePartInfo of cxf service model), we do type cast here, so 
if class has no @XmlRootElement, part.getXmlSchema() in following code 
will return XmlSchemaComplexType, but not XmlSchemaElement, which cause 
type cast exception as you see.


if ("POST".equals(method) || "PUT".equals(method)) {
            doc = IriDecoderHelper.interopolateParams(doc,

                                                     
(XmlSchemaElement)part.getXmlSchema(),

                                                     schemas,
                                                     params);
       } else {

           doc = 
IriDecoderHelper.buildDocument((XmlSchemaElement)part.getXmlSchema(),

                                                schemas,
                                                params);
       }

Cheers

Hi Freeman,


Here is my GetBook class. So I changed the @XmlRootElement by 
@XmlElement.

Actually I did it for the classes and only this one is causing problem.
Can you explain what is the problem in that case ?

Cheers
Tog

package com.acme.book

//import javax.xml.bind.annotation.XmlAttribute
import javax.xml.bind.annotation.XmlElement
import javax.xml.bind.annotation.XmlAccessorType
import javax.xml.bind.annotation.XmlAccessType

//@XmlRootElement(name = "Book", namespace="http://book.acme.com/";)

@XmlAccessorType(XmlAccessType.NONE)
//@XmlRootElement(name = "GetBook")
public class GetBook {
   @XmlElement
   long id
}

Hi  Tog,

I believe you remove @XmlRootElement(name = "GetBook") from you
GetBook.java, right?
I can reproduce your problem by means of removing @XmlRootElement(name =
"GetBook")

I think we should support your scenario.
Other guys, any thought?

I fill a jira to track it
https://issues.apache.org/jira/browse/CXF-680
Thanks very much

Freeman
