    IPC JSR 286 complex object as event

    antoine seilles Newbie

      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);
