Re: Mount files outside container
You mean you want Wicket to serve up files from outside of your webapp
directory? We do that at work with images. I just created a special
image resource class that basically just streams back the file
contents from the disk. Try something like this:
public class FileImageResource extends DynamicImageResource
{
private static final long serialVersionUID = 1L;
private final String path;
public FileImageResource( File file, String format )
{
super(format);
this.path = file.getAbsolutePath();
setCacheable(true);
setLastModifiedTime(Time.valueOf(file.lastModified()));
}
protected byte[] getImageData()
{
return FileUtils.getFileContents(new File(path));
}
}

Clicking "add to cart" repeatedly
I am new to Wicket (but not new to HTML, Java and Spring). I tried to follow the examples in the ebook of "Wicket in Action". Everything is fine until Chapter 3. I followed the cheese application which demonstrates a plain shopping cart. I compiled and ran the front page successfully (including the Index.html and Index.java, up to page 60). I could "add to cart" and "remove" successfully. So far so good. When I clicked "add to cart" repeatedly and slowly, it was still good. But If I clicked quickly enough, the following bunch of "Unexpected RuntimeException" appeared. I am not sure this is particular to this specific example or is general for other Wicket components. Did I miss something? Does anyone come across something similar? This is important if I am to propose Wicket in a serious project. Thank you very much!

Re: Mount files outside container
Thank you very much for the suggestion. By doing this I must add all my images from Wicket code. Let's say I want to server a logo, background image or something like that. And just do it via my markup file. Can this be achieved or do I have to use a servlet? -- View this message in context: http://www.nabble.com/Mount-files-outside-container-tp19232069p19233284.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

This is weird: The ClassNotFoundException suggests a classloader error, could be a bug in Tomcat though. Can you please post the whole stack trace?

Re: Mount files outside container
I would think you would have to use a servlet (unless they're in some location that can be served by your web browser).

Header contributions despite failed RENDER authorization
Hello, I have been playing around with authorization strategies and I have noticed that even though components that are not authorized to RENDER, its header contributions are still going through. I understand that isVisible != RENDER as discussed in previous threads however I feel there is a practical need to be able to prevent header contributions from going through if a component is not rendered. My case in point is that I have certain heavy components that should not be rendered to users not logged in and I would prefer that all the excess javascript, css and other header contributions are not displayed. As a temporary work around and I am overriding isVisible in these heavy components and doing the necessary authorization checks there. Although it works, it isn't very elegant as my authorization strategy is now decoupled across the whole application. Any thoughts on this are appreciated!

Re: Wizard question
Edward,
You could try something like:
class Step1 extends WizardStep {
public Step1() {
super("Step 1", "How many?");
add(new TextField("numberOfThings"));
}
};
class Step2 extends WizardStep {
public Step2() {
super("Things", "Now Enter As Many 'Things' As You Opted For");
add(new Loop("things", new
ComponentPropertyModel("numberOfThings")) {
@Override
protected void populateItem(LoopItem item) {
IModel model = thingModel(item.getIteration()); //
create model or reuse existing
item.add(new TextField("thing", model));
}
});
};
}
... where some ancestor has a CompoundPropertyModel whose model object has a
"numberOfThings" property and this model object's setNumberOfThings method
may also manage a list of models backed by "thing"s. Does that make sense?
Hej core devs, I was wondering when I'd use the Loop class - is this a
decent abuse of it?!

Re: Clicking "add to cart" repeatedly
I have gotten ClassNotFoundException several times. I repeatedly get it with 2 browser tabs opened and accessing the same page and doing some actions on the same page. I havent received any response from the Wicket team on this yet. I have also seen it happening with pressing back and forward buttons a few times. wil2008 wrote: > > I am new to Wicket (but not new to HTML, Java and Spring). > I tried to follow the examples in the ebook of "Wicket in Action". > Everything is fine until Chapter 3.
