Sun Java System Web Server 7.0 Update 6

Web Server 7.0 Update 6 is backward compatible with Web Server versions back to 7.0.

Web Server has no mandatory dependencies on other Java ES products, but it can optionally use Directory Server (in Directory Server Enterprise Edition) to provide LDAP-based authentication. When Directory Server is used, Web Server 7.0 Update 4 supports Directory Server versions 6.x.
