Chapter 4 Migrating Your Enterprise Server 55

JavaServer Pages

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

Web Server 4.1 and Enterprise Server 6.0 JSPs are written in JSP 1.1. Version 0.92 is

no longer supported in

Enterprise Server 6.0. JSPs must be rewritten according to

the version 1.1 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.

Any JSPs you have written in 0.92 will still work on Enterprise Server 6.0 as long as

they are in a designated legacy directory. To designate a directory as a legacy

directory, access the Class Manager, click the Services tab, and click Legacy JSP

Directory. Use this page to designate your legacy directories.

JSPs written in JSP 1.1 that are part of a web application can reside in any directory

that the server can serve from.

JSP 1.1 samples are in server_root/

plugins/samples/servlets/jsp.10.

Java Servlets

Enterprise Server 6.0 deprecates but maintains backward compatibility for the

iPlanet Web Server 4.1 style of servlets configuration using

servlets.properties,

rules.properties and contexts.properties files. These files may not be

supported in future releases of the product. For more information, see the Netscape

Enterprise Server Programmer’s Guide to Servlets.

Simple Session Manager

Simple Session Manager and JDBC Session Manager are supported by Enterprise

Server

6.0, but deprecated. Users are encouraged to use NESSession Manager

instead, which is described in the Netscape Enterprise Server Programmer’s Guide to

Servlets.

If your iPlanet Web Server 4.x web applications specified

SimpleSessionManager,

you should change the name of the class to

NESSessionManager. You then have the

option of adding persistence. Other

Init attributes such as timeOut and

reapInterval are unchanged.

If your iPlanet Web Server 4.x web application specified

JDBCSessionManager,

you should change the name of the class to NESSessionManager and add the

following attribute to the

init-param element of the session manager:

session-data-store=’com.netscape.server.http.session.JdbcStore’

Other attributes such as provider and url remain unchanged.
