So here is what I'm trying to achieve.
1. The tomcat install remains clean. I want to be able to change the
tomcat installation without messing with the app.
2. We want our applications to be decoupled from the libraries which it
needs. ( i understand the pains you are referring to.. this was a bit of
debate, but this is what we want to do).
3. We want our engineering team to manage libs via RPM, not the developers.
tomcat is installed like so via RPM.
/opt/tomcat-6.0.35
/opt/tomcat-7.0.39
/opt/tomcat-7.0.40
/tomcat symlinks to which ever /opt/tomcat-7.0.40
Context entries go in /tomcat/conf/Catalina/localhost/myApp.xml
/web/webapps - holds our webapps. This much works perfectly.
/web/conf/myApp - holds our application configs.
/web/lib - holds any libs that are not part of the base tomcat
installation. This is managed by rpm.
If unpack a war file, and it has contents inside WEB_INF/lib, we will
consider that a broken build.
Everything works, except that my libs are not loading.. I had thought that
I could add /web/lib,/web/lib/*.jar to the common.loader. Am I mistaken by
this?
Thanks,
Dan
