Vanessa,

Thanks for the resource. However, as I've been told, in-process/JNI 
is/will be deprecated and isn't recommended with Tomcat 5.5 and Apache 
2.x, and it appears that this particular configuration is trying to do 
that. Perhaps I've heard wrong. But I guess the confusion underscores 
the lack of documentation surrounding this area of Tomcat.
