Mohl by mi nekdo prosim poslat funkcni sampl jak udelat upload souboru
pomoci Seam-u ?
Mam JBoss Seam 1.2.1 (s nim dodavane myfaces) , tomcat 5.5.23 a nejsem
schopen to zprovoznit.
Pokud vyhodim tag:
<s:fileUpload data="#{photo.data}" contentType="#{photo.contentType}"
accept="images/png,images/jpg,images/gif"/>
tak ten form funguje.
Beanu mam zhruba takto:
@Entity
@Name("photo")
@Table(name = "photos")
public class Photo implements Serializable {
private static final long serialVersionUID = 169145795008850265L;
private Long id;
private String title;
private String contentType;
private byte[] data;
....
Pada mi to na tuhle vyjimku.
