Red Hat NETSCAPE ENTERPRISE SERVER 6.0 - PROGRAMMER GUIDE TO SERVLETS Uživatelský manuál stáhnout pdf (Strana 60)

iPlanet Web Server 6.0 supported both types of deployment schemes, but the 4.x

implementation (referred to as legacy servlets) was marked as deprecated (See Chapter 8:

“Legacy Servlet and JSP Conguration” of the iPlanet Web Server, Enterprise Edition

Programmer's Guide to Servlets).

Sun Java System Web Server 6.1 does not support Legacy Servlets. The legacy-style properties

les for the server you want to migrate - servlet.properties, context.properties, and

rules.properties - are removed during migration.

Because there is no one-to-one mapping for all of the features, legacy servlets cannot be

migrated automatically.

For documentation and samples to help you migrate your 4.x legacy-style servlets to the web

applications structure in Sun Java System Web Server 6.1, see the Sun Java System Web

Server 6.1 SP9 Programmer’s Guide to Web Applications.

Search Migration

Because the search engine used in Sun Java System Web Server 6.0 is replaced by a new search

engine in Sun Java System Web Server 6.1, existing search collections and indexes are not

migrated during the migration process. To use the Search functionality in Sun Java System Web

Server 6.1, you create and congure new search collections and indexes. For more information,

see the Sun Java System Web Server 6.1 SP9 Administrator’s Guide.

Security

Sun Java System Web Server provides new at le authentication and closer integration of

native access control with web application security constraints. However, core authentication

and authorization support is the same as in the version 6.0 release.

Sun Java System Web Server 6.1, apart from providing ACL-based authentication, also

leverages the security model dened in the J2SE Specication to provide several features that

help you develop and deploy secure Java Web applications. The J2SE/Servlet-based access

control infrastructure relies on the use of security realms.

In Sun Java System Web Server 6.1, authentication is performed by Java security realms which

are congured through AUTHREALM entries in the server.xml le. In case any such rules have

been set, authorization is performed by access control rules in the deployment descriptor le

web.xml,.

For more information about security-related features in Sun Java System Web Server 6.1, see

the Sun Java System Web Server 6.1 SP9 Administrator’s Guide and the Sun Java System Web

Server 6.1 SP9 Programmer’s Guide.
