RE: Barracuda: Html template compilation and classes reloading

In addition to what Jan has mentioned, Tomcat provides dynamic installation 
of contexts through Tomcat's Manager app.  In fact, Barracuda uses the 
Tomcat ant manager tasks to do this directly from the build.  So, what you 
can do is start Tomcat, edit Barracuda's build.properties file to specify a 
manager username and password of a Tomcat user (in tomcat-users.xml) which 
has an existing role of "manager", and then do the following....

ant install

That will build Barracuda and install it to Tomcat.  This make things go 
really fast.

You can then either remove or reload by doing, respectively...

ant remove
or
ant reload


BTW, this is also available for Diez' contrib project...

ant contrib -Dsubproject=dbroggisch -Dsutarget=install

Note that in the CVS on BarracudaMVC, this would be, respectively...

ant catalina-install

ant contrib -Dsubproject=dbroggisch -Dsutarget=catalina-install


And make sure to check out the stuff that Richard Kunze was talking about 
with the XMLC-2.2alpha3 reloading stuff.  Very cool!!!  Richard and David 
Li are doing a great job on it!!!  I also contributed a couple things to 
David Li's example app which fixes some classloading issues.  Not sure if 
that is all in CVS yet and it isn't in the latest alpha3, but it should be 
there soon.
