Hi Guan,

You've found a bug: the contents of thredds.war/WEB-INF/altContent/startup/
are *supposed* to be copied over to TOMCAT_ROOT/content/tredds/ if that
directory doesn't already exist, but that's never happening. We'll get a
fix for that in the next release (4.5.2).

In the meantime, you can simply copy over those files yourself to get
around the bug.

Thanks for the report!
