Access and Error Logs

The access and error server log les records the activity of the Server. During migration, new

access logs are created. Error logs from the 4.1server-instance/logs directory is copied to the

server-instance/logs in Sun Java System Web Server 6.1.

Conguration Files

Certain directives found in the iPlanet Web Server 4.1 magnus.conf le are now located in the

Sun Java System Web Server 6.1 server.xml le. During the migration process, these directives

are automatically removed from the 6.1 server’s magnus.conf le and added to the server.xml

le.

In addition, Init functions located in the iPlanet Web Server 4.1 obj.conf le are moved to the

Sun Java System Web Server 6.1 magnus.conf le.

For a list of deprecated directives, see the Sun Java System Web Server 6.1 SP9 Administrator’s

Conguration File Reference.

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

the Sun Java System Web Server 6.1 magnus.conf le.

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 Java

System Web Server 6.1. JSPs must be rewritten according to the version 1.2 standard. In

addition, Sun recommends 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

specication. This specication did not include web applications. A deployment scheme was

developed to make servlet deployment simpler. With the advent of Java Web Applications

(.war les) and their deployment descriptors, it is no longer necessary to maintain a proprietary

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 Conguration” of the iPlanet Web Server, Enterprise Edition Programmer's

Guide to Servlets.
