Uh, I forgot, PdfDataSource is final, so option B is not even an option
now ;)

Btw, there's a problem with current implementation. After the report is
done, you can't generated another report (e.g. clicking twice on the
same link). Because datasource is the same and it's at the end. So all
further calls to datasource.next() will result in false.
The solution now is either:
a) having datasource that can automatically rewind - not a big deal,
but perhaps problem when you have result set data source
b) using getDataSource as data source factory.
I think there should be more explicit way to specify data source factory
than overriding getDataSource. Or at least it should be mentioned in the
javadoc?
Any ideas?

Checked it out, I really like it. Mine was just a quick hack ;)

top of it, please check out whether you agree (find the patch
attached).

Hi.
There's a slight performace problem with JRResource, that it creates
JasperReport in it's constructor. I've 10 resource links on one
page so
it means that 10 JasperReports will be initialized everytime page is
created, even if none of them gets clicked. The performance penalty is
not small - 400ms.
So I think the JasperReport should be initialized lazyly, only when
the resource is really used.
I've atached "fixed" JRResource, it may not be the best solution, but
it works for me. (Look in the constructor(s) to see how it works)
