How can I persist the content of "xsd:any" tag using JAXB and EJB3?
Hello,
Using wsimport I generated a class from the following xsd type:
<xsd:complexType name="MDVendorExtensions_T">
<xsd:sequence>
<xsd:any namespace="##any" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</xsd:complexType>
The class generated was :
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name ="MDVendorExtensions_T", propOrder ={
"any"
})
publicclass MDVendorExtensionsT{
@XmlAnyElement(lax =true)
protected List any;
public List getAny(){
if (any ==null){
any =new ArrayList();
}
return this.any;
}
}
Then I would have liked to map MDVendorExtensionT into a database using ejb3 annotations. As I can't map a List<Object> I created an entity bean E just to wrap Object. So after adding persitent annotations:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name ="MDVendorExtensions_T", propOrder ={
"any"
})
@Entity
@Table(name ="MDV")
publicclass MDVendorExtensionsTimplements Serializable{
@Id
private Long id;
@XmlAnyElement(lax =true)
@OneToMany(cascade={CascadeType.ALL})
protected List<E> any;
....
with E containing just an id:
@Entity
publicclass Eimplements Serializable{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
..
If I have an xml file which contains an element vendorExtension that validate the xsd:any type defined above:
<root>
<vendorExtension>
<element1>first element<element1>
<element2> <element2_1> ....</element2_1></element2>
...
<vendorExtension>
</root>
My question is : how can I store the content of vendorExtension element into the database. There can be as many element as the user want under this element and if I try this code with just
<vendorExtension><element1>first Element <element1></vendorExtension>
I get a
java.lang.IllegalArgumentException: Object: [element1:null] is not a known entity type.
At first I wanted to store the content of vendorExtension as a string (I don't know how to do it either) but I think it's not a good solution if the content is very big
Thank you.
