Hi
Thanks for the answer petemuir!
I would like to get he Ajax4jsf solution working as everywhere I read it should
just work with seam 1.1 GA but I am have a problem...
I get the error...
javax.el.ELException: /home.xhtml: Bean:
demo.PaintBean$$EnhancerByCGLIB$$6f0837bd, property: paint

com.sun.facelets.compiler.AttributeInstruction.write(AttributeInstruction.java:53)

com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:232)
| at
com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239)
|
I added the following in my facelet...
<a4j:mediaOutput createContent="#{hello.renderImage}"
value="#{hello.value}.jpg" element="img" mimeType="image/jpeg" />
|
the following to my bean...
public void renderImage(OutputStream out, Object data) throws IOException {
| BufferedImage img = new BufferedImage(100,
| 50, BufferedImage.TYPE_INT_RGB);
| Graphics2D graphics2D = img.createGraphics();
| graphics2D.setBackground(Color.BLACK);
| graphics2D.setColor(Color.WHITE);
| graphics2D.clearRect(0, 0, 100, 50);
| graphics2D.drawLine(5, 5, 100 - 5, 50 - 5);
| graphics2D.drawChars(new String("Ajax4JSF").toCharArray(), 0, 8,
| 40, 15);
| graphics2D.drawChars(new String("mediaOutput").toCharArray(), 0,
| 11, 5, 45);
| ImageIO.write(img, "jpeg", out);
| }
|
|
the following to my interface...
public void renderImage(OutputStream out, Object data) throws
IOException;
|
|
and then deployed it.
If anyone has allready done this I would really appreciate a small example.
