Hi Alvaro,
that sounds odd to me. Given that the GET Resource does its job just
fine, and that the expected XML is being returned, I don't think the
problem actually is with castor in this case.
I'd raise a question with the Spring OXM guys at their forum(s), and
maybe post a link to the forum entry here so that we can listen in.
Regards

Hi all,
Im trying to create a simple Spring REST app using SpringOXM and Castor for
XML handling. So far so good, the problem is that when sending an XML POST
request to create a contact, Castor crashes complaining that:
<p>Problem accessing /contacts. Reason:
<pre> Server Error</pre></p><h3>Caused
by:</h3><pre>java.lang.IllegalStateException: No Introspector defined in
properties!
The simple xml Im sending looks like:
<?xml version="1.0" encoding="UTF-8"?>
<contact><name>Sonoo</name><lastName>Jaiswal</lastName></contact>
My mapping.xml:
<?xml version="1.0"?>
<mapping>
<class name="com.test.model.Contact">
<map-to xml="contact"/>
<field name="name" type="string">
<bind-xml name="name" node="element"/>
</field>
<field name="lastName" type="string">
<bind-xml name="lastName" node="element"/>
</field>
</class>
</mapping>
The Spring configuration:
<context:component-scan base-package="com.test />
<!-- REST service -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<util:list id="beanList">
<ref bean="castorMarshallingHttpMessageConverter" />
</util:list>
</property>
</bean>
<bean id="castorMarshallingHttpMessageConverter"
class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
<property name="marshaller" ref="castorMarshaller" />
<property name="unmarshaller" ref="castorMarshaller" />
</bean>
<bean id="castorMarshaller"
class="org.springframework.oxm.castor.CastorMarshaller">
<property name="mappingLocation"
value="classpath:com/test//model/mapping.xml" />
</bean>
And finally the controller looks like:
package com.test.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.http.HttpStatus;
@Controller
@RequestMapping("/contacts")
public class ContactsController {
@RequestMapping(value="/{name}", method = RequestMethod.GET)
@ResponseStatus(HttpStatus.OK)
@ResponseBody
public Contact getContact(@PathVariable String name) {
Contact c = new Contact();
c.setName(name);
c.setLastName("test");
return c;
}
@RequestMapping( method = RequestMethod.POST )
@ResponseStatus( HttpStatus.CREATED )
@ResponseBody
public Long create( @RequestBody Contact contact ){
System.out.println("Contact " + contact.getName());
return 1L;
}
}
As you see its a quick and dirty test to try out Castor and Spring OXM.
Actually, a GET request to the getContact method works and the xml is
returned, so the mapping.xml is loaded correctly.
Do you have any idea why Castor is crashing when unmarshalling the POST
request xml??
Thanks in advance,
A
