It depends on which operating system you're using and how you've
installed Tomcat.
Can you tell us which it is?

There is a (minor) difference between the two: JAVA
You can actually use JAVA_OPTS or CATALINA_OPTS to add the options and
the options only apply to JDK 1.5 or above. I don't think the version

In putting #1 into the JAVA_OPTS (which it appears that is the CATALINA_OPTS
for our implementation), it doesn't appear to work, as Tomcat doesn't
restart. It could be our version -- which is currently 5.0.30. please let
me know if there are other steps we need to take here as well.

Thanks! I've corrected the entries.

Tip #8:
You tell the users about the tomcat-users.xml file for adding the role
info but never tell them where to enter the RemoteAddrValve in order to
restrict IPs.

Chris,
Yes I agree that the extent at which #6 is implemented probably
depends a lot on the size of the app (namely the number of libraries).
There's already a link to the Tomcat original documentation for #3
although I noticed I forgot the link for #2.

Well... be careful on the use of the shared/common classloader. It
works as long as all the apps can use the same version of a library. If
there are changes to the API and you have the library in the shared or
common classloaders you'll have to upgrade all the webapps at once.

Good stuff
