First of all thanks for the replies. I copy my code if anyone is useful
ImagenDetails.tml
${uploadedImage}
ImagenDetails.java
@InjectPage
private ShowImagePage showImagePage;
@Property
private Imagen imagen;
public Link getUploadedImage(){
return showImagePage.getUploadedFile(imagen.getImagenId());
}
//Imagen is a entity with a property call ImagenId.
showImagePage.java
public class ShowImagePage {
@Inject
private LinkSource linkSource;
@Inject
private EstudioService estudioService;
private String contentType = "image/jpeg";// this is the default
private String extension = "jpg";
private String filename = "default";
public Link getUploadedFile(String imageId) {
return
linkSource.createPageRenderLink(ShowImagePage.class.getSimpleName(),false,
new Object[]{imageId});
}
public StreamResponse onActivate(final String imageId) {
this.filename = imageId;
return new StreamResponse() {
public String getContentType() {
return contentType;
}
public InputStream getStream() throws IOException {
Imagen imagen=null;
try {
imagen =
estudioService.findImagen(imageId);
} catch (InstanceNotFoundException e) {
// TODO Auto-generated catch
block
e.printStackTrace();
}
return estudioService.dicom2jpg(imagen.getNombreFich());
//dicom2jpg is a function that return a InputStream from a
.dcm file.
}
public void prepareResponse(Response response) {
response.setHeader("Content-Disposition",
"inline;filename=" + filename+ ((extension == null) ? "" : ("."
+extension)));
}
};
}
}
