This Services Gatekeeper course is a self-paced, offline course. Currently, only the course practices are available. The practices are provided in a PDF file and include step-by-step instructions. With its detailed, hands-on tutorials, you will walk away with a complete environment, suitable for prototyping and testing.

The Audience

The audience for this course are application developers, system architects, and integration developers who want to understand Services Gatekeeper.

Prerequisites

There are no mandatory prerequisites for this course.

The Practice Instructions

This Services Gatekeeper course is a self-paced, offline course. The practice instructions are provided as PDF files and include step-by-step instructions. With its detailed, hands-on tutorials, you will walk away with a complete environment that is suitable for prototyping and testing.

The Practice Environment

The practices use a virtual machine that you download and setup. The software that runs the virtual machines is Oracle VM Virtual Box. You need to have administrative rights on your computer to be able to disable or reconfigure any local firewall or CPU-intensive background processes, if necessary. The virtual machines require a computer that fulfills the following specifications:

• Operating System: Windows, Linux, OS X, or Solaris
• CPU: Preferably a dual core, at least 2 GHz
• RAM: At least 8 GB of RAM
• Hard Drive: At least 20 GB of free space

The Practice Structure

Interceptor Examples

This lab package contains the source code and build files for a couple of interceptor examples.
The instructions, which also are in the lab package, helps you unpack, compile, deploy and test the following interceptor examples:

• The Request Parameter Interceptor
  This interceptor unpacks the SMS message and appends a text to the end of the message.
• The Singleton Counter Interceptor
  This interceptor uses another class, Counter, which is a singleton. With each invocation of the interceptor, the number in the counter is increased and written to standard output.
• The Reject Dirty Message interceptor
  This interceptor unpacks the SMS message and if the message contains a word that is considered inappropriate, the whole message is rejected.
• The Request Context Attributes Interceptor
  This interceptor scans the Service Provider and and Application service level agreements (SLAs) and look for a couple of extra context attributes and prints the values of these to standard output.

These interceptors will help you get started to write, compile and deploy your own custom interceptors.

EDR Listeners

This lab package contains the source code and build files for two EDR listeners, one standalone and one deployable..

The instructions, which also are in the lab package, helps you unpack, compile, deploy and test these EDR listeners.

These EDR listeners will help you get started to write, compile and deploy your own custom EDR listeners.
