Found solution for Glassfish exceptions during initialization
Thanks to the information posted in Amy Roh's and Jean-Francois Arcand's blogs I have successfully integrated Glassfish with Apache to support multiple virtual hosts. Everything has been working fine until I started converting my webapps' webservices to use JAX-WS provided by Glassfish instead of Apache Axis.
To make a long story short Glassfish started throwing exceptions during appserver startup. Today I found the cause of the problem and a possible solution. In case anyone else is having the same problem I have posted a possible workaround in the comments section of Amy 's blog, FYI (http://weblogs.java.net/blog/amyroh/archive/2006/08/glassfish_suppo.html)
