Summary of Migration-Related Changes

86 Sun ONE Web Server 6.1 • Installation and Migration Guide • August 2003

Java Server Pages

iPlanet Web Server 4.0 Java Server Pages (JSPs) were written in JSP 0.92. The

iPlanet Web Server 4.1 and 6.0 JSPs are written in JSP 1.2. Version 0.92 is no longer

supported in Sun ONE Web Server 6.1. JSPs must be rewritten according to the

version 1.2 standard. In addition, it is recommended that developers create JSPs as

part of web applications. Style examples can be found in

server_root

/plugins/servlets/examples/web-apps.

JSPs written in JSP 1.2 that are part of a web application can reside in any directory

that the server can serve from.

JSP 1.2 samples are in server_root/

plugins/samples/servlets/jsp.10.

Java Servlets

Netscape Enterprise Server / iPlanet Web Server 4.0 and 4.1 supported the Java

Servlet 2.1 specification. This specification did not include web applications. A

deployment scheme was developed to make servlet deployment simpler. With the

advent of Java Web Applications (

.war files) and their deployment descriptors, it is

no longer necessary to maintain a proprietory deployment system.

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 Configuration” of the iPlanet Web Server,

Enterprise Edition Programmer's Guide to Servlets).

Sun ONE Web Server 6.1 no longer supports Legacy Servlets. The legacy-style

properties files 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 4.1 legacy-style servlets

to the web applications structure, see the Sun ONE Web Server 6.1 Programmer’s

Guide to Web Applications.

NOTE

During migration, multi-line Init directives are compressed to single-line

directives in the Sun ONE Web Server 6.1 magnus.conf file.
