java 没有带有 @XmlElementDecl 的 ObjectFactory

There's no ObjectFactory with an @XmlElementDecl

提问by Alexey Savchuk

To deploy in GlassFish Server Open Source Edition 3.1.1 (build 12):

要在 GlassFish Server 开源版 3.1.1（内部版本 12）中进行部署：

Caused by: java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions There's no ObjectFactory with an @XmlElementDecl for the element {http://www.w3.org/2004/08/xop/include}Include. this problem is related to the following location: at protected java.util.List ru.gosuslugi.smev.rev120315.ReferenceType.content at ru.gosuslugi.smev.rev120315.ReferenceType at public javax.xml.bind.JAXBElement ru.gosuslugi.smev.rev120315.ObjectFactory.createReference(ru.gosuslugi.smev.rev120315.ReferenceType) at ru.gosuslugi.smev.rev120315.ObjectFactory at protected java.util.List ru.gosuslugi.smev.rev120315.AppDataType.any at ru.gosuslugi.smev.rev120315.AppDataType at protected ru.gosuslugi.smev.rev120315.AppDataType ru.gosuslugi.smev.rev120315.MessageDataType.appData at ru.gosuslugi.smev.rev120315.MessageDataType at protected ru.gosuslugi.smev.rev120315.MessageDataType ru.gosuslugi.smev.rev120315.BaseMessageType.messageData at ru.gosuslugi.smev.rev120315.BaseMessageType

When a JAXB model is generated from an XML schema, I always recommend creating the JAXBContextusing the package name of the generated model.

当从 XML 模式生成 JAXB 模型时，我总是建议JAXBContext使用生成的模型的包名称创建。

JAXBContext jc = JAXBContext.newInstance("org.w3._2004._08.xop.include");

You don't specify what kind of application you are deploying to GlassFish, but if it is a JAX-RS/Jersey application I would recommend the use of a ContextResolver. This is a standard mechanism that gives you greater control over how your JAXBContextis created. Below is an example.

您没有指定要部署到 GlassFish 的应用程序类型，但如果它是 JAX-RS/Jersey 应用程序，我建议使用ContextResolver. 这是一种标准机制，可让您更好地控制自己JAXBContext的创建方式。下面是一个例子。

import java.util.*;
import javax.ws.rs.Produces;
import javax.ws.rs.ext.*;
import javax.xml.bind.*;
import org.eclipse.persistence.jaxb.JAXBContextFactory;

@Provider
@Produces({"application/xml", "application/json"})
public class SampleContextResolver implements ContextResolver<JAXBContext> {

    private JAXBContext jc;

    public SampleContextResolver() {
        try {
            jc = JAXBContext.newInstance("org.w3._2004._08.xop.include");
        } catch(JAXBException e) {
            throw new RuntimeException(e);
        }
    }

    public JAXBContext getContext(Class<?> clazz) {
        if(clazz.getPackage().getName().equals("org.w3._2004._08.xop.include")) {
            return jc;
        }
        return null;
    }

}

I faced exactly the same issue 6 months ago and honestly I don't remember how it was solved (probably we didn't need some functionality so we put it aside). But today once again our lovely stacktrace cursed with the message (literally like yours)

6 个月前我遇到了完全相同的问题，老实说我不记得它是如何解决的（可能我们不需要某些功能，所以我们把它放在一边）。但是今天我们可爱的堆栈跟踪再次被这条消息诅咒（字面上就像你的一样）

But this time I was able to deal with it.

但这一次我能够处理它。

There's nothing wrong with Include class. But somehow, and that's my guess, it doesn't get loaded properly for jaxb, or not at the time we need it, or ... whatever.

Include 类没有任何问题。但不知何故，这是我的猜测，它没有为 jaxb 正确加载，或者在我们需要它的时候没有加载，或者......无论如何。

What I was trying to do in my code is to validate a payload of the soap message.

我试图在我的代码中做的是验证soap消息的有效负载。

    JAXBContext jaxbContext = JAXBContext.newInstance(UnifoTransferMsg.class) ;
    SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = schemaFactory.newSchema(new File("UnifoTransferMsg.xsd"));

    Marshaller marshaller = jaxbContext.createMarshaller();
    marshaller.setSchema(schema);
    marshaller.marshal(inputmsg, System.out);

Spare me for the hardcoded values, it's just for debugging. Nonetheless the first line is where the exception is thrown because Jaxb somehow knows nothing about Include or uses the wrong class. To fix it one needs to load multiple classes at the same call.

给我留些硬编码值，它只是为了调试。尽管如此，第一行是抛出异常的地方，因为 Jaxb 不知何故对 Include 一无所知或使用了错误的类。要修复它，需要在同一个调用中加载多个类。

So the ultimate fix for me was

所以对我来说最终的解决办法是

JAXBContext.newInstance(Include.class, UnifoTransferMsg.class);

Hope that helps and maybe one day i'll expand more on the real cause of the problem.

希望这会有所帮助，也许有一天我会详细说明问题的真正原因。

You can try putting @XmlRoolElement annotation on generate Include class.

您可以尝试将 @XmlRoolElement 注释放在生成 Include 类上。
