Costin,

You can invoke Tomcat's main() directly. commons-launcher.jar is only 
required for the Launcher. The Launcher is really only a substitute for 
the old shell scripts. Ultimately, the Launcher uses reflection to 
invoke Tomcat's main() method.

So, commons-launcher.jar is only a dependency if you want to distribute 
the catalina.[sh|bat] scripts in that are in the bin directory.

If you are embedding Tomcat 5 (like Sun does with J2EE), you do not need 
commons-launcher.jar at all. Or, if you want to ship Tomcat with your 
own customized scripts (like Sun does with JWSDP), you do not need 
commons-launcher.jar either.

Hope that clears things up,

Patrick
