Re: [Babeldoc-devel] Babeldoc development

[Bruce M. <br...@mc...>]

Dejan, All:

I am about to make the first release of the RC1 codebase.  This code
is now completely restructured and is ready for the public.  The finishing 
touches will include crypto and j2ee support and I dont know about the 
j2ee.  The last significant hurdle breached today was how babeldoc finds 
its modules when running in a web container.  I introduced a system 
property that tells babeldoc module handling code to scan one or more 
directories for candidate files.  This sounds like a major hack but its 
actuall quite subtle.  Heres the deal:

a Servlet in Tomcat/catalina needs to have all of its libraries in the 
./shared/lib or in the webapp/<war>/WEB-INF/lib directory.  Now, I opted 
to put all the code in shared lib to avoid very bloated war files  and to 
encourage code sharing.  The catalina script to start the web container 
gets started with the environment variable JAVA_OPTS which has the sytem 
property of the directory to scan, which is the shared lib.  As babeldoc 
starts, it scans this directory and finds all the modules.  There is NO 
other way for 3rd party modules to get stuff into the classpath (the 
catalina script disregards the CLASSPATH).

How do we automate the copying over of the libs and the wars to the 
catalina directory.  This is handled by a script which is copied from the 
web/bin directory to the build/bin directory.  It has a number of tokens 
(of the form @token-name@) which get filled in by the build scripts when 
the copy is performed.  The values for the tokens come from the 
modules/web/build.properties file but can be overriden in a top-level 
file, called locals.properties.  These properties tell the script where to 
find catalina, the location of the shared directory and the actual name of 
the script to start catalina. 

so to build and deploy the babeldoc web stuff do this:

c:\babeldoc>build
c:\babeldoc>build\bin\catalina start

this assumes that catalina is in a directory:
\babeldoc\..\tomcat.v4.1

fair enough.

Bruce.
