4:49 p.m.
I get a very similar exception myself, using Seam 1.1GA, and Ajax4JSF 1.0.5 with the
<a4j:mediaOutput> tag.
I'm wanting to display an image I have stored in my database, but also, in order to
eliminate mis-configuration of my own application as a factor, I've modified the Hotel
booking example thus:
in Hotel.java, I've added:
@Transient private byte[] image;
|
| public Hotel() {
| try {
| FileInputStream fis = new FileInputStream("/testimage.png");
| image = new byte[8000];
| fis.read(image);
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
|
| public void renderImage(OutputStream out, Object data) throws IOException {
| out.write(this.image);
| }
and in view/hotel.xhtml:
<div class="label">Image:</div>
| <div class="output">
| <a4j:mediaOutput createContent="#{hotel.renderImage}"
value="#{hotel.name}.png" element="img" mimeType="image/png"
/>
| </div>
and I get this exception:
ERROR
[org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/seam-booking].[Faces
Servlet]] Servlet.service() for servlet Faces Servlet threw exception
