使用JAXB的jersey webservices中的xml语法无效

Question

I am using jersey web services which consumes POST request as an xml and produces response as an xml. I am using JAXB to marshal/Unmarshal xml into Java bean. Here "TestCall" is a class which stores all the attributes specified in request,but in case XML is malformed(ie end tag missing) in request, i need to return ERROR code in response XML. so how to handle these scenario ?

Here is my code:

@POST 
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.APPLICATION_XML)
@Path("/testCall")
@Override
public TestCallOutput postCall(TestCall testCall) 
    return myService.acceptCallData(testCall);
}

I am marshal the xml using below 2 classes:

import javax.xml.bind.annotation.XmlRegistry;
@XmlRegistry
public class ObjectFactory {


/**
 * Create a new ObjectFactory that can be used to create new instances of schema 
 * 
 */
public ObjectFactory() {
}

/**
 * Create an instance of {@link TestCall }
 * 
 */
public Ivrcall createTestcall() {
    return new Testcall();
}

}

and

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {

})
@XmlRootElement(name = "testcall")
public class TestCall {

/** The method. */
@XmlElement(required = true)
protected String method;

/** The dateref. */
@XmlElement(required = true)
protected String dateref;

/** The timeref. */
@XmlElement(required = true)
protected String timeref;

/** Getters and Setters of elements 
... */
}    

I need to return response in xml like below: <testcall> <status>ERROR</status> <msgid>0001</msgid> <msgtxt>INVALID XML DOCUMENT</msgtxt> </testcall>

The stack should handle this for you by returning a 500 error to the client. You don't need to do any work.

Edit: if you insist on implementing this (I would push back if I were you, unless you're required to be compliant to an existing interface), you should add a JAX-WS handler ( javax.xml.ws.handler.Handler ) and override handleFault to check for the specific exception that JAX-WS throws when it can't unmarshal the incoming message. Then create the response XML in the handler.
