Subject Re: 3.0 annotations ?
Date Tue, 04 Aug 2009 20:22:46 GMT
Thanks - so objectweb instead of BCEL.
I'll try it out - it's a bit different from what I had in mind, it looks
like xbean-finder first finds all classes and
than reads the files using the class loader ( but not Class.forName, which
is good ) and keeps track of all annotations.

I was thinking of a simple File/zip based scanning, without any class loader
- and just select the few
annotations we need and write a web.xml fragment as it goes, without keeping
anything in memory.
I guess in 3.0 a deploy tool / phase is absolutely needed - we can't have
tomcat scan all files
each time it starts up, so the user will have to do something to re-initiate
the scanning. Like touch
web.xml, or run a re-deploy tool.

 I'm curious - why objectweb and not BCEL ?
