JBoss:JaxB数据处理程序兼容性

Question

我正在使用JBoss 5.1（EAP）。我正在使用Spring webservice（3.0.5）。对于编组，我使用JaxB。

我正在使用maven。jaxb2。用于从模式（xsd）生成pojo的插件。

当我在JBoss上部署EAR时，我得到以下错误：

    19:05:52,524 ERROR [[eventmanager-ws]] Allocate exception for servlet eventmanager-ws
    com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
    javax.activation.DataHandler does not have a no-arg default constructor.
            this problem is related to the following location:

我已经检查了jaxb2插件版本，并尝试使用以前的版本，假设JBoss得到了JaxB2.1.12，尝试了许多版本，但没有运气。

有什么建议吗？

谢谢，阿迪

在实体中的某个地方，您有类型为DataHandler的字段。用@javax标记此字段。xml。绑定注释。XmlTransient注释

class SomeEntity  
{  
    //...   
   @javax.xml.bind.annotation.XmlTransient  
   private javax.activation.DataHandler yourField;  
   // ...  
}
