Subject [Fwd: progress report on XSLTC]]

Strange. This was addressed to the dev list, but it does not appear in 
my local list archive. Anyway, these are great news, kudos for the XSLTC 
team for the work they have been doing so far.

Anyone volunteering for testing the new xsltc.jar? I can make it 
available somewhere for the brave :-)

Thanks again Tom,

Hi,

Making progress. I took the xsltc-enabled war file Gianugo sent me
yesterday, fixed the syntax used for calling the static external
java functions in book2menu.xsl, and was able to reproduce a
problem in XSLTC when clicking in the Doucmentation link on the
splash page.

Santiago came up with a fix for the problem which was due to
XSLTC returning a null local name. With the one line fix, I was
able to get a lot further.

The Documentation link (with fix for null local name) now works.

HTML, XHTML, PDF, XLS, and SVG JPEG all worked

Search link -- didn't work, giving following error because XSLTC doesn't 
support nonstatic external Java functions.
  Compiler warning(s):

Samples -> Hello World -- blew up but doesn't look like its XSLTC's 
problem.

We'll have to look into this broken pipe problem.

Adding support for nonstatic external java functions looks important and
is on our list.

I've attached a version of xsltc.jar with the fix for the null local 
name. You
may want to use it to see how far you can get. There may be somethings 
you can
change on your side.

Tom
