The Template Java Generator or tjava is a Perl module for the generation of Java source code via the Perl Template toolkit.
0.4 is finally out!
It is now possible for anyone to generate Java bean source from simple XML description files, or table schemas in a database, the beans fully parse themselves from and to XML using SAX 1.0!
You will need a beta version of the Template toolkit from CPAN (2.x, 1.x will not work, I'm pretty sure). You can find it here. Scroll down to "Template-Toolkit".
You can find instructions on how to install CPAN modules here.
You can find tjava itself along with any (mostly none) documentation on CPAN and on the SourceForge page.
