634 IBM Eserver i5 and iSeries System Handbook

Product positioning: WebSphere Application Server and Jakarta

Tomcat

The strategic Web application server from IBM is WebSphere Application Server.

The latest version of WebSphere Application Server is Version 5.1. All

WebSphere Application Server offerings support Servlets, JSPs, EJBs, and

more.

Some iSeries customers want a basic, no-cost Web application server that

supports servlets and JavaServer Pages. Relying on the IBM HTTP Server

(powered by Apache) as its Web server, the Apache Software Foundation’s

Jakarta Tomcat provides a basic Web application server for iSeries customers.

Jakarta Tomcat is available with OS/400 and at no additional cost to customers.

Jakarta Tomcat is offered as a way for iSeries customers to “get started” with

Java server-side components and Web application serving. Customers should

select WebSphere Application Server when they need to deploy on demand

business solutions that are J2EE compliant, provide the most function, and

deliver the highest levels of reliability, scalability, and security.

If an IBM or Solution Developer application requires WebSphere Application

Server as the base Web application server, do not consider Jakarta Tomcat as

an alternative Web application server. Examples of IBM products that require

WebSphere Application Server as the base Web application server include

WebSphere Commerce, WebSphere Payment Manager, and WebSphere Host

Publisher.

Customers who require a robust and scalable Web application server can select

WebSphere Application Server. Jakarta Tomcat provides fewer functions and

capabilities compared to the IBM WebSphere Application Server. For example,

Jakarta Tomcat does not support Enterprise JavaBeans, is not J2EE compliant,

and does not provide Domino integration.

For more information, see iSeries e-business Handbook: A Technology and

Product Reference, SG24-5694.
