JBoss: compatibilità JaxB DataHandler

Question

Utilizzo JBoss 5.1 (EAP). Sto usando Spring webservices (3.0.5). Per il marshalling sto usando JaxB.

Sto usando maven.jaxb2.plugin per generare pojo dallo schema (xsd).

Quando schiero l'orecchio sul JBoss, ottengo il seguente errore:

 
    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:

Ho controllato la versione plug-in e jaxb2 provato a usare la versione precedente con il presupposto che il JBoss ha JAXB 2.1.12, provato molte versioni ma senza fortuna.

Qualche suggerimento?

Grazie, Adi

Answer 1

qualche parte nella tua entità avete campo con tipo DataHandler. Segnare questo campo con @javax.xml.bind.annotation.XmlTransient annotazione

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