Why Is Integration With Domino Important?
 Each cornerstone Lotus product fulfills distinct customer needs
 Domino - Established, well-known app development and messaging system
 Portal - Innovative way to integrate apps running on a variety of systems
 Workplace – Build vertically-integrated, collaborating apps on a portal base
 “Blended” Domino / Portal / Workplace apps will be very common
 The appdev mix is based on a customer’s specific business needs
• Varies from customer to customer
• Will vary over time
 Domino plays a long-term role in our plans
 Will be providing enhancements, new tools, etc. for years and years to come
 We are committed to preserving and enhancing your Domino investment

Integrating Domino With Other Products
1 Use the Domino Designer
To extend and integrate new features into existing Domino applications
2/3 Use the CAPI and its Extension Manager
To add your own server tasks and to enhance the behavior of a Domino server
4 Use a program that interfaces with Domino’s HTTP task
To get Domino data back as HTML or XML and to invoke Domino application agents
5 Use a locally-installed Notes client or Domino server to use NRPC
To have C/C++, VB, and Java programs work with remote Domino apps via NRPC
6 Use NCSO.jar and Domino’s DIIOP task
To have your Java programs work with remote Domino apps without having to have a
locally-installed copy of the Notes client or the Domino server

“remote”
Java
program
A Server-side Implementation Of The Notes Client
 A web browser provides the user interface
 URL commands with arguments are sent by the browser to Domino
 Domino returns a page of HTML
 Can emulate much of what the “rich” Notes Client can do
 But still limited by browser limitations and server latency
 Have introduced web-oriented design elements to help close the gap
 Most useful command for integration – ReadViewEntries
 Returns view entries as XML
 In many cases this is more convenient and useful than using the Java
backend classes
 We are investigating putting ReadViewEntries into the other APIs
15
Portal Integration Uses Domino HTTP In Two Ways
 Run existing Domino web applications
 Some issues to resolve, but we have a roadmap to resolve them
• Domino Web Application Portlet (DWAP)
• More about DWAP later in the presentation
 Get view data via the ReadViewEntries command
 Used by the Lotus Collaborative Components API
16

NRPC
Notes Remote
Procedure Calls
17
NRPC – Notes Remote Procedure Calls
 Standalone C, C++,
VB, and Java
programs call APIs
of locally-installed
Domino function
libraries
 Domino, in turn,
uses NRPC to call
the equivalent
service on a remote

Using NRPC From An External System
 Install the Notes Client or Domino Server on the system
 This is just to get NOS’ dynamic link libraries onto the system so that
your program can call into them
 You do not actually need to run Domino or Notes, just install it
 Works well in small standalone or client-like applications
 Gives standalone C, C++, Java, and VB programs a way to integrate
Domino data into their applications
 Can be problematic when used by complex server systems
 It is like having two servers run in the same process space
• Servers often assume the can use all available resources, so
there may be conflicts over memory usage, signal handlers, etc.
 WAS applications will experience problems running Domino locally
24
Connecting To Domino
Remote Java
Domino’s DIIOP Task
25
DIIOP – What Is It?
 Common Object Request Broker Architecture (CORBA)
 It’s a specification and not a product
 Controlled by OMG consortium (Object Management Group)
 Main purpose
• Allow objects on servers invoked remotely by Clients
• Data transfer between Object Oriented systems
 CORBA’s Internet Inter-Orb Protocol (IIOP)
 Defines how Orbs talk across the wire to each other
 DIIOP is Domino’s implementation of IIOP
 Provides a platform-independent industry-standard way for Java
programs to access Domino backend objects across a network
26
Local Versus Remote Java
 One Domino Java API, two implementations
 Use Notes.jar to link to a local copy of Domino backend classes
 Use NCSO.jar (Notes Client Side Objects) coupled with DIIOP to
give your Java programs access to remote Domino backend classes
Non-Domino system

DIIOP And Domino-WAS Integration
 The primary way for Java programs in WAS to access Domino
 Useful for Websphere apps leveraging Domino data using JSP tags
 Needed for Portal applications using Domino infrastructure
 We’ve made many improvements to DIIOP in Domino 6.0x
 6.0 removed the need to run HTTP task in order to get the IOR
• Running HTTP was a concern for some users
 Significantly improved scaleability and removed many performance
bottlenecks
 More improvements planned for 7.0x and beyond
 We will address session timeout issue in the next release
 We are investigating removing more performance bottlenecks
28
Integrating With Domino
DXL
A new integration option
29
Domino XML Language (DXL)
 Domino content represented as XML
 Tags and attributes for Domino databases, documents, design
elements, fields (text, numbers, richtext, …), etc.
 Can export DXL from Domino and import DXL to Domino
 A powerful new way to manipulate Domino content using XML
 Nearly all Domino content is available, not just those objects
available through the traditional APIs
• Goal is to represent 100% of Domino data as DXL
 Available now
 Available in CAPI and LotusScript since N/D 6.0
 Available in VB, local Java, and remote Java since N/D 6.5
• Various Lotus Portal and Workplace apps are just now starting to
use DXL to integrate with Domino data
 Investigating adding a ReadDXL URL command for the HTTP task

46
DWAP Resolves Issues
Running Existing Web Applications Well As Portlets
 Reverse proxy issue
 The Portal Server is an example of a reverse proxy server
• All request from outside the enterprise should funnel through it
and none should directly access backend systems
• Most existing web apps, including Domino web apps, prepare
browser pages with HTML links directly back to themselves
− This is especially hard to detect when there is Javascript in
the page that generates links dynamically on the browser
 HTML table issues
 The Portal Server uses HTML tables to layout portlets in a page
• Namespace collisions can occur when combining HTML from
different backend systems that do not know about each other
• Many existing web apps generate tags not allowed in table cells
− Some examples: HEAD, FRAME, FRAMESET, etc.
47
Domino Web Application Portlet
Coming in Domino 6.5.1, Q1 2004
 Designed to allow Domino web apps to be surfaced in a
LWP/Portal environment
 Delivered as iframe first, web clipper in later releases
 A low cost and more efficient way to resolve issues rather than using
additional reverse-proxy servers and iframes
 Implements a reverse-proxy portlet
 DWAP uses a set of rules to map Domino generated URLs to
Workplace/Portal such that all requests are channeled through Portal
 This new technology will eventually become part of the Portal core
 Security features
 SSO – supports SSO between Workplace/Portal and Domino
 SSL – supportS secure transfer of data between Workplace/Portal and
Domino
48
Domino Web Application Portlet – View mode

49
Portlets and Portlet Builders
 Out-of-the-box portlets
 Portlets can be installed and used
immediately.
 Faster development
 Business power users create portlets
through the portal UI
 Access to SAP, PeopleSoft, JDBC,
Domino, Siebel
 Fast execution
 Portlets use connectors to access
application through application's own
native interface.
 UI flexibility
 Look and feel of portlet can be
customized.
 Takes advantage of front-end
integration portal technology like Click
to Action and People Awareness
50
Portlet Builder for Domino
 A portlet to build Domino portlets
Simple Web interface to create portlets that access / manipulate data
in Domino
No programming required
