JAXB - IllegalAnnotationExceptions

Question

我有一個這樣的XSD：

<xs:element name="Measure"> 
<xs:complexType> 
    <xs:sequence> 
    <xs:element minOccurs="1" ref="Measure_Id"/> 
    <xs:choice minOccurs="1" maxOccurs ="4"> 
     <xs:element ref="Measure_Value"/> 
     <xs:element ref="Measure_Value_Max"/> 
     <xs:element ref="Measure_Value_Min"/> 
     <xs:element ref="Measure_Value_Average"/> 
    </xs:choice> 
    <xs:element minOccurs="0" ref="Files"/> 
    </xs:sequence> 
</xs:complexType> 
</xs:element> 

特別地，具有<xs:choice>我想指定元件Measure必須有至少一種類型的Measure_Value。 不幸的是這種代碼生成一個例外：

com.sun.xml.bind.v2.runtime.IllegalAnnotationsException：IllegalAnnotationExceptions 1個計數有與元素{} Measure_Value_Max的@XmlElementDecl沒有的ObjectFactory。

我必須做些什麼來解決這個問題呢？

我用Netbeans 7.4和jdk1.7。

此外，在我的架構的另一部分，這種限制的正常工作！爲什麼？

<xs:element name="UD_Info"> 
<xs:complexType> 
    <xs:sequence> 
    <xs:element minOccurs="1" ref="UD_Identificator"/> 
    <xs:choice minOccurs="1" maxOccurs ="3"> 
     <xs:element ref="UD_Measures"/> 
     <xs:element ref="UD_Alarms"/> 
     <xs:element ref="UD_Diagnostics"/> 
    </xs:choice>   
    </xs:sequence> 
</xs:complexType> 
</xs:element>

There's no ObjectFactory with an @XmlElementDecl for the element {}Measure_Value_Max.

爲了讓您需要無論是在把它作爲用來引導JAXBContext，或在的包名創建JAXBContext類之一ObjectFactory過程生成模型。
