IPC JSR 286 complex object as event

[natoine]

I try to communicate an objetc from a portlet to another using EventPortlet.

My event is a serializable object.

I have the following error when testing my portlets :

Cause: java.lang.IllegalArgumentException: The provided event value type fr.natoine.annotations_persistence.selection.SelectionHTML does not have a valid jaxb annotation

Message: The provided event value type fr.natoine.annotations_persistence.selection.SelectionHTML does not have a valid jaxb annotation

My object/event code :

@Entity
public class SelectionHTML extends Selection 
{
     @Column(name = "SELECTIONHTML_CONTENT")
     private String content;

     public String getContent() {
          return content;
     }

     public void setContent(String content) {
          this.content = content;
     }
}

SelectionHTML extends Selection :

@MappedSuperclass
@Table(name = "SELECTION")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
public abstract class Selection implements Serializable
{
          @Id @GeneratedValue
         @Column(name = "SELECTION_ID")
         private Long id;
          @Column(name = "SELECTION_URL_SOURCE")
          private String url_source;
          @Column(name = "SELECTION_BEGIN")
          private String begin;
          @Column(name = "SELECTION_END")
          private String end;
          
          public Selection(){};
          
          public Long getId() {
               return id;
          }
          public String getUrl_source() {
               return url_source;
          }
          public void setUrl_source(String urlSource) {
               url_source = urlSource;
          }
          public String getBegin() {
               return begin;
          }
          public void setBegin(String begin) {
               this.begin = begin;
          }
          public String getEnd() {
               return end;
          }
          public void setEnd(String end) {
               this.end = end;
          }
}

I use Hibernate Annotations cause i use these classes for persistence.

I declare my event in portlet.xml :

<event-definition>
          <qname>annotation-selection</qname>
          <value-type>fr.natoine.annotations_persistence.selection.Selection</value-type>
</event-definition>

And i send my event :

SelectionHTML _selection_html = new SelectionHTML();
_selection_html.setUrl_source(request.getParameter("url"));
_selection_html.setContent(request.getParameter("text_selection"));
_selection_html.setBegin(request.getParameter("xpointer_start"));
_selection_html.setEnd(request.getParameter("xpointer_end"));
response.setEvent("annotation-selection", _selection_html);

Did you try the jaxb annotation?

@Entity
@XmlRootElement
public class SelectionHTML extends Selection 
{

Thank you.

That's what i did and it works.
