During migration you can choose to install either the JDK that is bundled with Sun Java System

Web Server 6.1 (JDK 1.4.2_13) or install a custom JDK. If you install the server with a custom

JDK, the javahome setting of the migrated instance refers to the custom JDK path (taken from

the javahome setting of the Administration Server). Otherwise the javahome setting points to

/bin/https/jdk.

Sun Java System Web Server 6.1 supports the Java Development Kit (JDK) version 1.4 and

above. It does not support a standalone Java Runtime Environment (JRE).

In the Sun Java System Web Server 6.1 this data is stored in the server.xml le.

The JAVA element in the new server.xml le contains the JDK conguration information

copied from the start-jvm le of the migrated instance.

The JVMOPTIONS element in the new server.xml le contains the JVM options information

from the jvm12.conf le of the migrated instance.

If the previous version of your server was congured to use JDK 1.4.1 or above, the NSES_JDK

path from the server’s start-jvm le is copied into the Sun Java System Web Server 6.1

server.xml le, otherwise, the JDK path points to server-root/bin/https/jdk, which is the

default JDK path in Sun Java System Web Server 6.1.

For information about the mapping of the start-jvm and jvm12.conf les with the

server.xml le in Sun Java System Web Server 6.1, refer to the Sun Java System Web Server 6.1

Administrator’s Conguration File Reference.

Java Server Pages

Sun Java System Web Server 6.1 supports Java Server Pages (JSP) 1.2 specication. The JSP092

object representing JSP version 0.92 is no longer supported in Sun Java System Web Server 6.1

and is deleted during migration.

Style examples using JSP 1.2 can be found in the following directory:

server_root/plugins/servlets/examples/web-apps/.

Legacy Servlets

Sun Java System Web Server 6.1 supports the Servlet 2.3 specication.

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.
