Hi all,
Thanks for the replies! I checked out your link Barry - it doesn't seem to
be exactly what I want. (I'll explain later in the reply... I'm still new
to mailing lists).
Thiago & Jens:
How I'm doing fetching-code-outside is someone writes a .java file that
implements an interface. Say it has function a, b and c they have to
implement. They then compile this into a class, put it into a program and
link it to the set of data they want to render. Then, when using the web
interface the application will detect when its loading the set of data and
load it into its own class (not overwriting), create a new instance and
then use functions a, b and c to render the data into the webpage. This is
already working - but currently how it is done is that the user has to
hardcode their HTML into the .class file and do things like \"<div>" +
escapeHTML(data) + "</div>";\ instead of it having a template system where
they could go <div>${data}</div> and then the application would use the
tapestry template/component system.
An example usage for this would be, for example, a library that wants to
digitize its pages and then have it available online to be viewed through
the application. The library could store the files in an XML format like
so: http://da.viddiaz.com/example.xml and then use the following
hypothetical code and .tml to render it: http://da.viddiaz.com/code.txt
http://da.viddiaz.com/code.tml
Then this library could have different sets of data that wouldn't match
this exact set of data - it might have sets of emails (so then you could
write an email renderer), MARC data and so on. These examples are basic -
in the real world the data is a lot more complex! I hope this makes a bit
more sense why I would need to take this approach.
In regards to the Dynamic component, I must have messed up using it. Still
though, the problem would be getting it linked up to the .class file that
is loaded so that the user could then use tapestry in there (otherwise the
ComponentResources would be the .tml file that loaded it, not the
dynamically loaded one).
The stack trace I was getting is here, although I don't think it's really
useful: http://da.viddiaz.com/stacktrace.txt
Thanks,
David.
