There is problem with some missing XSD schemas on located on geronimo
web server.
if you use schema location to make Eclipse validate XML document it
complains
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1
http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1">
that it can not find geronimo-naming-1.2.xsd and geronimo-module-1.2.xsd
these both files are referenced from
http://geronimo.apache.org/xml/ns/j2ee/web-2.0.1 Other referenced files
seems to be at correct location. Please upload these two too. There
might be more missing files, if i will spot one, i will mail you.
