Alfresco deployment on Tomcat

I'm building Alfresco from source and want to deploy it on Tomcat. Can please anybody explain this to me ? There is not enough information about it here .

APP_TOMCAT_HOME (can be used to host the Slingshot webapp)

VIRTUAL_TOMCAT_HOME (NOTE: this must be a totally separate installation of Tomcat; it is required for virtualization) 

I suppose that APP_TOMCAT_HOME can be the same location as TOMCAT_HOME, but what about the virtualization ? What is it about ? Why ?

I found this thread and it is like :

Forget about virtualization server

• In that case, the build script deploys stuff in to ${env.var.that.is.not.set}

I end up with

java.lang.ClassNotFoundException: org.apache.catalina.storeconfig.StoreConfigLifecycleListener

From what I read in here Virtualization_Server_FAQ , I don't need it at all, but the build script kinda count on the VIRTUAL_TOMCAT_HOME variable and it deploys some tomcat 5.x stuff like common and server directories

Finally I tried to find what is going on in this wiki entry but it is also "out of context" ...

This is How far I got :

Thank you

The virtualization server is a customized Tomcat instance that is used to run the Java application that implements the presentation layer of structured content managed through a WCM project in Alfresco. The ant script provides a way to apply the customizations to a standard Tomcat distributions to enable it to work as a virtualization server. You can safely ignore it, most likely.

APP_TOMCAT_HOME should point to a Tomcat distribution folder that will host Alfresco Share, while TOMCAT_HOME will host Alfresco Repository. They can be the same server.

I was able to reproduce the very same issue, which appears to occur when the Tomcat process runs out of memory during Alfresco deployment. Try again with increased memory limits, like:

tomcat-6.0.29$ export JAVA_OPTS="-Xmx512m -XX:MaxPermSize=160m"
tomcat-6.0.29$ bin/startup.sh

Have a look also to the suggested JVM settings.
