I don't need to mount images "dynamicaly" (at the moment of the user click).
For example
I have image logo.png and it's loaded just once when app start and mounted at
some url path. This path
is still same, not needed to be loaded dynamicaly "when user click". For this
purpose this 'mountResource("/images/logo.png", new
PackageResourceReference(Images.class, "logo.png"))'
works perfect. Now this image is in DB and I need to do same think. I have data
(from DB), I have mount
point (from DB), but can't mount on url:
AppStart.get().getSharedResources().add(imagePath, imageData);
Looks that wicket "somethink do" because this events about images in log:
127.0.0.1 - - [04/Nov/2013:23:52:09 +0100] "GET /images/images/headerbackground.png
HTTP/1.1" 302 -
127.0.0.1 - - [04/Nov/2013:23:52:09 +0100] "GET
/images/images/headerbackground.png?52 HTTP/1.1" 200 9077
127.0.0.1 - - [04/Nov/2013:23:52:09 +0100] "GET /images/images/cz-ico.gif
HTTP/1.1" 302 -
127.0.0.1 - - [04/Nov/2013:23:52:09 +0100] "GET /images/images/icon-fb.png
HTTP/1.1" 302 -
but don't know what's wrong with
'WebApplication.get().getSharedResources().add(imagePath, imageData)'

Martin, thank, I have read it (have the book), but don't find any info why
this:
I am not sure we talk about the same thing.
The blog article is not related to any book. And additionally it shows how
to load images from DB dynamically. It doesn't use shared resources though.
All you have to do is to mount a resource reference that listens at
"/images/${imageName}" and then put <img src="/images/logo.png"/> in your
.html.
AppStart.get().getSharedResources().add(imagePath, imageData);
from my code below not working.
Guess that example is for dynamicly loaded images but my example is for
static
images in database (website logo etc) not for dynamic loaded images.
Originaly I have done it in this way:
mountResource("/images/logo.png", new PackageResourceReference(Images.class,
"logo.png"));
and it works smoothly. Now I moved images into database and looking for
way how to serve them.
In fact, I have image data but not know hot to mount this data into
defined path:
AppStart.get().getSharedResources().add(imagePath, imageData)

Hi folks!
I'm using wicket 1.5.10, tomcat 7 and Java 6. In my code i do:
public final class Images{
public static void mountGlobalStaticImages(){
//loading images from database works perfect
List<Object> imagesParams = GlobalTemplatesDAO.getGlobalImages();
for(Object record : imagesParams){
Map<String, Object> image = (Map<String, Object>) record;
//it's path like '/images/mylogo.png'
String imagePath = (String) image.get("file_mount_point");
//ComponentDynamicImage is extended DynamicImageResource, looks it
works (it provides required byte[] data)
ComponentDynamicImage imageData = new
ComponentDynamicImage((byte[])
image.get("file_data"));
//problem is here: looks that it mount image isn't in app and in
log
is http status code '302'
//AppStart is extended WebApplication class
AppStart.get().getSharedResources().add(imagePath, imageData);
}
}
}
Problem is that images isn't here, in localhost_access_log.2013-11-
04.txt
are lines:
127.0.0.1 - - [04/Nov/2013:23:52:09 +0100] "GET

How to mount them properly? As far as i know problem is in
'AppStart.get().
getSharedResources().add(imagePath, imageData)'
but not know how to do it properly.
