Hi,
according to this document, I made the following Resource class that works perfectly:
@Scope(ScopeType.APPLICATION)
@Name("imageDelivery")
@BypassInterceptors
public class ImageDelivery extends AbstractResource {
/**
* The maximum width allowed for image rescaling
*/
private static final int MAX_IMAGE_WIDTH = 1024;
@Override
public String getResourcePath() {
return "/imageDelivery";
}
@Override
public void getResource(final HttpServletRequest request, final HttpServletResponse response)
throws ServletException, IOException {
new ContextualHttpServletRequest(request) {
@Override
public void process() throws IOException {
doWork(request, response);
}
}.run();
}
private void doWork(HttpServletRequest request, HttpServletResponse response) throws IOException {
}
}
Then I had to call a Seam component called uiOptions that looks like this:
@Name("uiOptions")
@Scope(ScopeType.CONVERSATION)
@Synchronized
public class UIOptions {
@In FacesContext facesContext;
...etc...
}
I get the component from the doWork method using this code:
UIOptions uiOptions = (UIOptions) Component.getInstance("uiOptions", true);The problem is that when I call some method of uiOptions that use facesContext it give me the following error:
org.jboss.seam.RequiredException: @In attribute requires non-null value: uiOptions.facesContext
so facesContext doesn't exists (is null) on injecting from a resource call, if I use uiOptions in the normal way (for example inside XHTML) it works perfectly...
Any idea on how to make it works?
Thanks a lot!
