Thank you Bas.
Here my implementation: maybe it will help someone:
public class AvatarResourceReference extends ResourceReference {
private final IUserService userService;
public AvatarResourceReference(IUserService userService) {
super(AvatarResourceReference.class.getName());
this.userService = userService;
}
@Override
public IResource getResource() {
return new AbstractResource() {
@Override
protected ResourceResponse newResourceResponse(Attributes
attributes) {
final ResourceResponse res = new ResourceResponse();
// Check if the user has the role for the DASHBOARD
// FIXME Add authorization with ROLES
// if
(!AuthenticatedWebSession.get().getRoles().contains("DASHBOARD")) {
// res.setError(HttpServletResponse.SC_FORBIDDEN);
// return res;
// }
// If the user PID est missing the request, return an HTTP error
final StringValue userPidValue =
attributes.getParameters().get("userPid");
if (userPidValue.isEmpty()) {
res.setError(HttpServletResponse.SC_NOT_FOUND);
return res;
}
// Search the requested user. If not found, return an error
final Optional<UserProfile> userProfile =
userService.findUserByPid(userPidValue.toString());
if (userProfile.isEmpty()) {
res.setError(HttpServletResponse.SC_NOT_FOUND);
return res;
}
final UserProfile user = userProfile.get();
if (user.getAvatar() != null) {
res.setContentType(user.getAvatar().getContentType());
} else {
res.setContentType("image/png");
}
res.setWriteCallback(new WriteCallback() {
@Override
public void writeData(Attributes attributes) throws
IOException {
attributes.getResponse().write(getUserAvatar(user));
}
});
return res;
}
};
}
private byte[] getUserAvatar(UserProfile userProfile) {
if (userProfile.getAvatar() != null) {
return userProfile.getAvatar().getData();
} else {
try {
return
IOUtils.toByteArray(Objects.requireNonNull(UserListPanel.class.getResourceAsStream("avatar-unknown.png")));
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
}
I'm using MarcGiffing framework. Here the initiailization of the resource
reference:
public void init(WebApplication webApplication) {
webApplication.mountResource(String.format("/dashboard/resources/%s/${userPid}",
AvatarResourceReference.class.getName()), new
AvatarResourceReference(userService));
}

Objet : Re: Image without page versioning
Hi!
Since you are using an image component with a component-local resource, this
will always require the page to be versioned.
The url that is generated for the image will be page-specific, to be able to
let the image component call the byte array resource.
If you wish to keep the page stateless, you’ll need to use a mounted resource
for this.
You can create a mounted resource that gets the active user from the session
(or return a 404 when the user is not logged in); Or you can build a stateless
version which has some unique user identifier in the url.
