I'm looking for example of jee web applications that has pre-configuration feature.

I mean first time opening web application in the browser, jump to installation / configuration page and allow

1. configute all of parameters, like database, user, password etc

2. run db script

3. other installation tasks

I do such analyze to know, which way is preferrable - add web-based pre-configuration feature to web application or build classic installer. (InstallAnywhere, Install4j)
