Lotus Domino Designer 8: Web Agents and Web Services
Lotus Training Overview

The Domino HTTP server task is extremely versatile. In addition to its HTML rendering tasks, it also executes several types of design elements coded in Java or LotusScript:

  • Agents run by a Formís WebQueryOpen and WebQuerySave events.
  • Agents run by the ?OpenAgent URL command.
  • Web Services that run in response to a SOAP request message.
This course covers the development and security of these design elements. You will also learn debugging and run time error handling techniques.

This course also takes a close look at Web Service client requirements and teaches you how to code a simple Web Service client using a SOAP toolkit.

Lotus Training Course goals

In this course, you will learn how to: This course will teach you how to:
  • Describe the differences and application of Agents run from a Formís WebQueryOpen and WebQuerySave events and those run from the ?OpenAgent URL command.
  • Code Agents run by the Formís WebQueryOpen event to work within the document context as well as perform lookups to other databases.
  • Conditionally run WebQueryOpen Agents depending on document state.
  • Define the server, database, and Agent security measures and ensure that Agents are run in the proper context.
  • Code Agents run by the Formís WebQuerySave event to translate and validate user entries and provide useful feedback to users and redirect them to natural landing points in the application.
  • Code Agents run by the ?OpenAgent URL command to perform powerful actions and produce reports from Domino data, and learn different ways that a browser can run the ?OpenAgent command.
  • Debug Agent code and add run time error handling routines as well as how to analyze Agent-specific browser errors.
  • Define the key components and protocols of Web Services technology.
  • Use Web Services Explorer to perform basic testing of a Web Service.
  • Describe the differences between the various Web Services programming models and SOAP message formats as they apply to Web Services design element properties.
  • Code Web Services using LotusScript that accept simple and complex data types as parameters.
  • Code a simple Web Services client that runs from a browser and uses a SOAP toolkit.
  • Import a WSDL to create a LotusScript library that can be used by Notes or Domino to consume a Web Service.
  • Debug Web Services provider and client code and handle runtime code errors as well as SOAP faults.
  • Employ the Remote Debugging, Agent Logging, Profiling, and DDM Probe features to fully analyze Agent and Web Service operation and performance.
Lotus Training Audience

This course is designed for experienced programmers well versed in using Domino Designer 8. It assumes that you have:
  • thorough knowledge of the Domino Designer 8 development environment, including Form and View design, as well as how to use properties boxes, and how to set the ACL
  • mastered the Topics covered in these courses:
  • Domino Designer 8: Basic Notes Applications
  • Domino Designer 8: Basic Browser Applications
  • knowledge of Web technologies, including servers, browsers, HTML, Cascading Style Sheets, and some basic JavaScript.
While mastery is not expected, you should have a working understanding of LotusScript and the various Notes product objects.

This course is part of a series of Domino Designer 8 training courses. Follow these paths to master all aspects of developing applications using Domino Designer:



Domino Designer 8: Basic Notes Applications provides the base knowledge for this additional training:


Client Track

  • Configure Domino to use DB2 as a database engine and build applications that access relational data, DB2 for Domino 8 Administrators and Developers.
  • Specialize in programming Notes applications to respond to built-in user interface features, Domino Designer 8: Special Notes Features.
  • Convert an application written for Notes clients to be used in browsers, Domino Designer 8: Basic Browser Applications.
  • Provide data to cutting-edge Web applications, Domino Designer 8: Web Agents and Web Services.
Language Track. These languages apply to both Notes and browser clients:

  • Learn sophisticated application techniques that fully exploit the formula language in Domino Designer 8: Formula Language.
  • Develop sophisticated applications and Agents with LotusScript in Domino Designer 8: LotusScript.
  • Add powerful client-side scripting to browser applications in Domino Designer 8: JavaScript.
Course design

This is a lecture/lab course that follows a task-oriented approach. During the many course exercises you will create a working application from the ground up. As you learn about various aspects of Domino Designer, you will immediately apply the concepts and techniques as you work on your application.
