There a number of additional classes being discovered by javap (above the list you supplied). Yes, that list was just the top level classes. There's lots of extras that get referenced by those classes. Do you want these to be typecast to 'Any'? In the short term, yes. In the longer term we'll need to be more flexible. I envisage a 'type map' file that, for each Java type, specifies the corresponding Perl6 type (either builtin or in a module). Any types not in the file would generate a warning and map to Any. Feel free to add that in! I'd guess it would be straight-forward. Rakudo currently doesn't support 'Array of' - so the returns parameters are now returning 'Array' without a type, I've included the type info in a comment at the end of line. Method parameters just get the appropriate sigil now. Typecasting was causing several multi methods to end up with the same signature, I've amended the generator to remove the duplicates. Great. I added them to a copy of the list and it starts bring in stuff like the Java print system classes etc. when run against java2perl. Not quite sure what you mean there Dave. Do you want a snapshot of what I've done so far, or would you rather wait until it's more complete? Commit early, commit often :) What sort of Google account do I need to commit? Go to google.com. Click 'Sign in' in the top righthand corner. Click 'Create an account now'. Enter your email address etc. Send me the email address when you're done. Or, if you already have a google account, just send me one of the email addresses associated with the account. Thanks! Tim.
Re: DBDI Status
Tim
Attached is a modified copy of the Generator::Std that emits current
perl6. It's been amended to add the correct sigils and 'use' statements.
Do you want to give it a try and see if it does what you want?

Is there a particular reference implementation of java.sql(x) you're
planning on running the java2perl on? A quick google shows a reference API
but no obvious reference implementation.
Any implementation that has the classes will do. java2perl6 is only
concerned with the class interfaces. It just runs javap on the class
you give it, parses the class and interfaces definitions it outputs, and
writes corresponding perl6 clasess and roles definitions.
Try running
java2perl6 --outdir jdbc --recurse --nest java.sql.Connection
I've just checked in a file I had on my disk that lists all the
java.sql and javax.sql classess, so you can run
java2perl6 --outdir jdbc --recurse --nest $(cat jdbc_classes.txt)

Hi
Hi Dave.
Has anything happened with a Parrot JDBC implementation?
Is Parrot stable enough yet?
Has anyone mapped out the minimun subset of JDBC that would be required
to get DBI working in Perl6?
Here's the (current) plan...
1. Dust off java2perl6
http://search.cpan.org/perldoc?java2perl6
http://code.google.com/p/java2perl6/
and update it to generate valid current perl6 code.
2. Add a type aliasing mechanism (ie for the Java URL type use a Perl
Str type) to java2perl6 so we don't have to implement loads of Java
types before we can get started.
3. Write some kind of very dumb Hello World skeleton JDBC driver,
as a proof of concept that uses the interfaces generated by java2perl
4. Refactor Simon Cozens's SQLite3 DBDI driver to use ('consume') the
generated JDBC interfaces.
http://dev.simon-cozens.org/6pan/browser/trunk/DBDI/DBDI/Driver/SQLite3.pm
That's not working right now, so here's a cached version:
http://google.com/search?q=cache:T8FN2WYvgm0J:dev.simon-cozens.org/6pan/browser/trunk/DBDI/DBDI/Driver/SQLite3.pm
Making a move on this has been high on my list of pre-OSCON tasks
but working on NYTProf has remained a higher priority (there are some
great new features in the next release).
If anyone wants to help out with 1 and 2, you'd be more than welcome!
