Unmarshalling Error: unexpected element (uri:url, local:“objectname”). Expected elements are <{}objectname>

Question

I\'m using jaxb2-marshaller to generate classes to communicate with a webservice. Java-classes are generated with use of some wsdl files.

Everything is okay now, but whe

Answer 1

I think I found the problem.

I was using the 0.9.0 version of the maven-jaxb2-plugin. This version gave me that strange exception! I reverted to the 0.8.3 version of maven-jaxbe2-plugin, this version throws a 404 error:

Answer 2

Please use the following annotation

@XmlRootElement(name="Customer")

at the root of the class as shown below. Since JAXb wont create @XmlRootElement annotation automatically, you need to manually put this annotation at the top of the class.

 The generated ObjectFactory class:

Answer 3

This trace is generated because of the names of de request and response message are not de same in the WSDL and de java class:

Reponse Message:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "acceptMessageResponse", propOrder = {
    "acceptMessageReturn"
})
public class AcceptMessageResponse {

    @XmlElement(required = true)
    protected String acceptMessageReturn;

    public String getAcceptMessageReturn() {
        return acceptMessageReturn;
    }
    public void setAcceptMessageReturn(String value) {
        this.acceptMessageReturn = value;
    }
}

Accept Message:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "acceptMessage", propOrder = {
    "in0"
})
public class AcceptMessage {

    @XmlElement(required = true)
    protected String in0;

    public String getIn0() {
        return in0;
    }
    public void setIn0(String value) {
        this.in0 = value;
    }
}

In this example the WSDL must define: 1.

Answer 4

If you have more than 1 module in your project check for duplicate Class names or directory names.

I was getting the same error and I was able to resolve it by changing the package names in my project.

I had two modules in my project with identical directory structures module/src/main/java/com/example/directory/path

We had two different endpoints and 2 different WSDLs, but both were from the same client. When we auto-generated the POJO classes from the WSDLs it created the file structure for us. I noticed that the namespace generated in the XML was using the same namespace for XML generated in both modules, when they were supposed to be different (hence the stacktrace).

All I did to solve the problem was change the directory names to be more specific for each module.

Answer 5

• Either your original schema does not have the right target namespace.
• Or you're somehow missing the package-info.java

Please post your ObjectFactory and package-info.java (must be generated next to the ObjectFactory).

You actually don't have to create your instances via ObjectFactory, normal new constructions work fine. :) ObjectFactory does no magic. It is primarily used by JAXB during unmarshalling.

ps. Please tag the maven-jaxb2-plugin-related questions with the maven-jaxb2-plugin tag - this will get my attention quicker.
