 Lotus products for IBM i (i5/OS)
| | |
IBM provides a number of enhancements to Domino and WebSphere to more tightly integrate these two products. This page outlines the current key integration points and includes a compilation of links to general Domino and WebSphere integration information and more specific information on their implementations on System i.
For coexistence information between Domino, WebSphere and i5/OS, see the Domino and WebSphere release compatibility Web page.
With Domino 6 and later releases, WebSphere and Domino are even more tightly integrated. Domino users are entitled to a restricted-license version of WebSphere Application Server. WebSphere is the strategic direction with regard to Domino and J2EE (JSPs, EJBs and Servlets). For information regarding the restricted license that is available for using WebSphere with Domino 6, see the Domino 6 and 7/WebSphere Entitlement FAQ.
The four cornerstones of Domino and WebSphere integration available on System i with Domino 6 and later releases include:
Single Signon (SSO)
From the end user’s perspective, true integration mandates that the user is authenticated once, then is free to access all authorized resources in the web domain, without having to re-authenticate. A feature to allow this, called Single Signon (SSO), allows a user to sign on only one time when accessing applications that are shared between WebSphere and Domino.
This feature is available with Domino 6 for i5/OS and later release with WAS 5.0 Express, WAS 5.1, 6.0, 6.1 ND and Base and later release:
For WAS 5.0 Express:
For WAS 5.1:
For WAS 6.0:
For WAS 6.1:
WebSphere servlet access to Domino databases
WebSphere applications can access Domino databases using the Lotus-supplied Java classes. There is an article in the January 2001 edition of the WebSphere Advisor magazine – Tips for Working with Domino Objects – that discusses this topic. The article offers two approaches to accessing Domino objects from WebSphere; local or remote. Using remote access is strongly recommend since it offers simpler setup, a higher degree of portability, and more flexibility with security.
This feature is available on System i with Domino 6 for i5/OS and later releases and WAS 5.0 Express, WAS 5.1, 6.0, 6.1 ND and Base and later release:
Using Domino HTTP Server to access WebSphere resources
WebSphere can be configured to use the Domino HTTP server instead of the IBM System i HTTP Server using the Domino Web Server API (DSAPI). This is one way to converge your web servers to just a single instance, potentially reducing administrative overhead.
This feature is available on System i with Domino 6 for i5/OS and later releases and WAS 5.0 Express, WAS 5.1, 6.0, 6.1 ND and Base and later release:
IBM HTTP Server (powered by Apache) Domino plugin
With Domino 6 and later releases, the IBM HTTP Server (powered by Apache) is also supported. This is a significant improvement over the support provided with IBM HTTP Server (original) in Domino R5. One key value add is the ability to easily setup and configure one HTTP Server to manage both Domino and WebSphere requests.
For more information, see the HTTP Server (powered by Apache) plugin for Domino on i5/OS.
