Tomcat -Installanywhere

Hello guys,
I would like to know if anyone can help me out in packaging something like setup.exe that can install all the files needed for the project and update the tomcat config files.
-update the server.xml file for adding new context
-setting up the paths for tomcat
-install my project in tomcat.
-setting up the paths for jdk home
-user should be able to select wether he wants to install tomcat, jdk etc.
i am using tomcat 4.0 , win2000.
any sort of light is thankful

Having a web-application you should build a *.war file shouldn't you?
If you changed something extra in tomcats configfiles you need to remember it and give it as installation note.
packaging this into an installation.exe file, is something I would like to know too. E.g. the installation of sun Java packages is done like this with accept, path info (registry additions) etc.
One solution is: buy a install make program.
There seems to be a Java install possibility:
java -jar "file".jar install
Altogether (sorry), your question was not totally clear to me.
