Re: XMLC 2.2 Alpha 2 and Examples released (Download location)

Hi David,

Turns out that I am able to get it to build.  I also had to remove
xerces-1.4.4-xmlc-2.1.jar from JAVA_HOME/jre/lib/endorsed which I have
there for Building Barracuda/XMLC-2.1 apps.  I also had to remove
XercesImpl.jar from ANT_HOME/lib.  The xml-apis.jar was fine to
leave there.  Note that previously with xerces-1.4.4-xmlc-2.1.jar in
the endorsed directory I didn't have to remove the existing Xerces jar
from ANT_HOME/lib since the Xerces I put in the endorsed dir overrode
Ant's local version of Xerces.

I guess this situation isn't too bad, but Ant-1.5.1 comes with
Xerces-2.x.x and telling users to delete XercesImpl.jar from ANT_HOME/lib
when other apps might need that existing isn't so good.  Also, I am
concerned about the fact that putting the Xerces version that come with
XMLC into Java's endorsed dir doesn't work.  I wonder if it has to
do with the fact that we can't specify a classpath on the <xmlc ...
/> task?  Hmm.... Weirdness abounds with this classloading
stuff.

Anyway, now that I can build I guess I'll check this reloading stuff
out!

later,

Jake
