Hm, possibly easiest would be to create the resource when it is
requested only.
What component are you using to integrate the resource in your page?

IMHO ResourceStreamResource#internalGetResourceStream() should check for
an already created stream and return that one. The way it is implemented
now looks like a bug.

I also cannot only return a new IResourceStream when it's not instantiated
yet in my ResourceStreamResource, because the AttachmentInputStream from
Ektorp is not serializable, I get errors if I try that. As far as my
knowledge goes I see myself with no option left..

Thanks for the idea, but I can't do that. That would make my resources
static and all attachments would be loaded at page load. I did that at the
beginning, and of course that's a very flawed concept because I would run
into huge performance and memory-problems even with just one user.
So I need the ResourceStreamResource to be dynamic. I don't get why the *
getResourceStream()* is called multiple times.. the javadoc for that
method says
Lazy or dynamic initialization (...)
How can I get proper dynamic resource then?

Beware that ResourceStreamResource#**getResourceStream() is called
multiple times.
Probably easiest is to create the resource stream in
CouchDbAttachmentStreamResourc**e's constructor and pass it to super.

Hi,
I wanted to, but I can't because then I don't have the stream to close
it.
If I don't close the stream returned by the Ektorp getAttachment()
method I
will have memory leaks.

Without looking to deep into this you should create the InputStream in
CouchDbResourceStream#****getInputStream() instead of the constructor.

Hi, short question this time: I have several ResourceLinks to
ResourceStreamResources on a page. When I click on one of those links,
the
resource streams attachments dynamically out of my database.
That's working quite well now, however the stream (and whatever
happens in
the method returning the streams) is called 2-4 times. E.g. opening an
image results in 4 queries to the CouchDB database. I don't really see
that
happening when I'm playing an mp3 file with a flash-player pointing to
the
URL of the resource.
Does anyone have an idea why? I'm only instantiating the resource once,
for
any link I only use that one resource.
Here's my custom ResourceStreamResource: http://pastebin.com/9BB7LEiV
And here my custom IResouceStream: http://pastebin.com/Z7GvzGja
Thanks!
