javax.xml.bind.UnmarshaleException:意外元素（uri:“本地：”ProcessCreditApplication“）。预期的要素是

以下是java jaxb解组代码：

    private void fillProcessCreditApplication() {
    try {
        JAXBContext jaxbContext = JAXBContext.newInstance(ProcessCreditApplication.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        ProcessCreditApplication processCreditApplication = (ProcessCreditApplication) jaxbUnmarshaller.unmarshal(xml);
    } catch (JAXBException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

例外情况如下：

javax.xml.bind.UnmarshaleException:意外元素（uri:，本地：“ProcessCreditApplication”）。预期要素包括：

这是什么意思？ 以下是xjc生成的ProcessCreditApplication java代码：

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ProcessCreditApplication", propOrder = {
    "applicationArea",
    "dataArea"
})
public class ProcessCreditApplication {

    @XmlElement(name = "ApplicationArea", required = true)
    protected ApplicationArea applicationArea;
    @XmlElement(name = "DataArea", required = true)
    protected ProcessCreditApplicationDataArea dataArea;
...

@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.starstandards.org/STAR", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
    package org.starstandards.star;

ApplicationArea.java和ProcessCreditApplicationData.java与ProcessCreditApplication.java位于同一文件夹中

以下是传入的xml：

<?xml version="1.0" encoding="utf-8"?>
<ProcessCreditApplication xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <ApplicationArea>
    <Sender>
...

编辑：以下是生成的ProcessCreditApplicationDataArea类的代码：

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ProcessCreditApplicationDataArea", propOrder = {
    "process",
    "creditApplication"
})
public class ProcessCreditApplicationDataArea {
