DynamicWebResource in WWB

[zabian]

Hi,
I would like to put something like ResourceLink in the WicketWebBeans
list to return DynamicWebResource to the client, actually generate
some PDF document.
Do you know any good idea how to do it using WWB (ajaxTarget, form,
bean) approach?

You can combine WWB with regular Wicket on the same page. WWB's components are just regular Wicket components. This way you can take advantage of the best of both worlds.  Alternately, you could create an action in WWB. When the action is clicked, you generate the PDF and return it.

Thanks for reply,
I know I can combine Wicket with WWB, but i would like to have this
link on WWB generated list, so I think I suppose to use WWB action.
The problem is how to return generated file to the client. Should I
write usual servlet and send request to it when the action is clicked?

I can't see any help, so because I found the solution I would like to
share with you:

public class PDFResource extends DynamicWebResource{
........
}

And this snipet to put into an action:

IResourceStream resourceStream = new PDFResource
(bean).getResourceStream();
getRequestCycle().setRequestTarget( new ResourceStreamRequestTarget
(resourceStream) {
public String getFileName() {
return bean.getNumber() + ".pdf"; } });

Actually the solution I found originally was:
IResourceStream resourceStream = new ByteArrayResourceStream(pdf,
"application/pdf");

where pdf is an array of bytes
byte[] pdf = ...;

but I couldn't find ByteArrayResourceStream class.
Does anybody know where I can find it?

Hi zabian,

Check this post:

http://www.mail-archive.com/us...@wicket.apache.org/msg24529.html

Also I suggest you to check this site:

http://grepcode.com/

it's great for navigating java source code and searching for
classes.

Hth,

Thank you, It was really helpful, because I use FOP in my application.
grepcode.com - really nice tool.
I was using similar - http://koders.com for browsing sources and
another useful http://findjar.com for looking for missing classes and
libraries.
