Question

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

我正在使用maven.jaxb2.plugin从架构（xsd）生成pojo。

当我在JBoss上部署EAR时，我收到以下错误：

    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JaxB 2.1.12，尝试了很多版本但没有运气。

有什么建议吗？

谢谢，阿迪

您实体中的某个地方有字段DataHandler。标记此字段 @javax.xml.bind.annotation.XmlTransient注释

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

JBoss：JaxB DataHandler兼容性
