Hello and sorry to barge in...

I am but a humble tinkerer who wants to customise the Web Export plugin a bit
before
outputting his library.

Specifically, I'm wanting to add a barcode into each book's page on export,
something that
will probably be of little use eventually, but might give me some limited
personal
satisfaction (and I do have a barcode scanner, so it isn't just for aesthetic
reasons). I can
generate ISBN barcodes in a standard web page easily enough by calling a PHP
page to
generate an image on the fly, (eg: "<img src=barcode.php?code=1583671021>"), but
am
stumped as to how I can actually modify Web Exporter.app in the first place to
place the
relevant code on each book's page.

I've opened up the package, gone to src/resources/Java/net/aetherial/books/
webexporter/WebExporter.java and played around with that file in a way that my
enfeebled
mind considered would output what I wanted, but this hasn't made any difference
to the
output of the Web Exporter.

Could someone just point me on the right track? Do I need to *do* something
(other than
save) with the modified Java file before the modifications will take effect? I
feel just
providing the ability for people with limited understanding of css and html to
customise
some elements of the Web Exporter would lend enormous flexibility to the
software, but at
the moment it all seems just a bit over my head.

Kind Regards,
James.
