Thanks Carsten!

I got my source working now, but it's awfully slow. The source gets a specially modified zip-file from any cocoon source (context used) and after working on it, extracts a file from this zipped package. The slow section seems to be the unzipping part. Also, no caching seems to happen by Cocoon. A web page that called this source 10 times took 20 seconds to load on a fairly fast machine. The zip file is only 84Kb!

Any optimization tips? Didn't think Java's zip-utilities are so slow...

Hi,

I'm writing a custom Source and SourceFactory for Cocoon, which takes uris in this form: mysource:context://foo/bar.zip:mydir/myfile.gif.

The part between the two ":"'s is a "sub-uri", which I need to resolve. How can I do this, so that any Cocoon URI works, for example: cocoon://foo.bar and html://foo.bar ? The Source stuff seems to be changed lately, so what is the right way to go?

Just implement a SourceFactory with your own Source - you can lookup
the SourceResolver in your implementation and use the resolver to
resolve any Cocoon uri. So in your example above, you have a factory
for your mysource: protocol and inside the factory you use the
resolver to resolve the context: protocol.

There is only one subtle trick with using a resolver inside a
source factory: you can't lookup this component inside the service()
method. If you do so, you end up in an initialization loop.
You have to do a lazy look up of the resolver: the first time you
really need it.
