Tomcat, Synaptic Package Manager: help

[alis]

Hi
I have a big problem that raise a big question for me.

Question: What is the different between Tomcat that is installed by Synaptic Package Manager and Tomcat that is downloaded from tomcat.apache.org ?

Problem: I have a web application (Liferay4) that I can easily install it on Tomcat from tomcat.apache.org but I can't yet (after trying for a week) install it on Tomcat installed by Synaptic Package Manager.

there probably isnt any difference.
from what i can gather, manually installing a download from a website means you have to install its dependencys seperately.
when you install a program through synaptic package manager you will install the dependancys with the program aswell.
this also means you can uninstall the dependencys with synaptic aswell weheras if you have to manually uninstall it you will leave the dependancys installed leaving rubbish consuming space.

im new to ubuntu myself so if im wrong im sorry and someone will have to correct me

I'm not sure about diffrences but one that I have founded is that there is no "catalina.properties" in CATALINA_HOME/conf.

And a similer question: Where SPM gets Tomcat form and how it know how to install it?
