Hello David, There are tools/scripts which try to automate the process of chrooting an application, i.e, guessing libraries needed and so on. But they usually require additional work (fine-tunning, etc), trial&error tests, etc. Being Tomcat/Java a common application (at least amongst this list's users), I had supposed some of you have already done this work and could share with me their findings/work, so I could anticipate problems, issues, etc.
