i have something similar, an image servlet, rather than re write to load
from wicket, see what i did
add(new Image("imageFromServlet", new ServletImageDynamicResource());
private final class ServletImageDynamicResource extends DynamicImageResource
{
private byte[] imagegif = null;
protected byte[] getImageData() {
if (imagegif != null) {
return imagegif ;
}
imagegif = loadGIFData();
return imagegif ;
}
private final byte[] loadGIFData() {
ByteArrayOutputStream outgif = new ByteArrayOutputStream();
InputStream in = null;
try {
java.net.URL url = new java.net.URL("
http://localhost:8084/app/imgservlet";);
URLConnection huc = url.openConnection();
huc.setRequestProperty("user-agent", "Mozilla(MSIE)");
in = huc.getInputStream();
int i = 0;
while((i = in.read()) != -1 )
{
outgif.write(i);
}
} catch (IOException ex) {
ex.printStackTrace();
} finally{
}
}
return outgif.toByteArray();
}
}
