Metacat

The current readme for Metacat 1.2 says: The build.xml file now has a
property named datafilepath. It should be set
to the location of where you want your data files stored. If you are an
existing user, this directory should be /<tomcatdir>/webapps/metacat/data
where <tomcatdir> is the your tomcat installation directory where
your webapps directory is located and 'metacat' is the name of your servlet
instance."

It should be changed to something like:

Your datafiles should not be stored in the /<tomcatdir>/webapps/metacat/
path but somewhere else in order to prevent a webuser from access to stored
data. For unix users, the data directory needs to be writeable by whatever
user is running tomcat.
