How can I find out my Tomcat-Version, if Tomcat-Directory is renamed?

[hootch0815]

Hello @ all.
I don't know the version of a tomcat-server. Usually there runs 3 tomcat, and thus the directories are renamed from tomcat-4.x.x.y to tomcat.cleintxy.
I have to know, what versions are running.
Can everybody help me in this simple but having problem?

My problem is solved by myself.
I have typed in my browser:

http://server-ip:spec.-port/applicationname

and can see, it ist the 4.1.18

Thats it!
Bye
