I just had the same problem the other day, you can fix this by adding a "User Specified XML Catalog Entry"
for the spring-2.2.xsd in Eclipse:

"XML" -> "XML Catalog"
you can check the XML Catalog Entries for
the spring-2.2.xsd file, if it is missing you can add it from the latest src tarball, its at
Thanks Michael, your suggestion is of great help.
