This sample demonstrates how to run a simple stateless rule session on a Java EE application server.

Time required

10 minutes

Prerequisites

You must have Rule Execution Server installed to use this sample. The product comes with a WebSphere Liberty sample server that includes Rule Execution Server. You can use the sample on a different application server, but you must first install Rule Execution Server on the server.

Description

In this sample, you learn how to run a simple stateless rule session from a web application for several application servers:

WebSphere Liberty 16 (sample server)
WebSphere® Application Server 8.5.5
Oracle WebLogic Server 12.1.13
Tomcat 8

If your application server supports Enterprise JavaBeans (EJB), you can run the sample on the web by using Java™ Server Pages (JSP) or a Java client.

Important: For the remote client to work, you must first deploy the appropriate rule session beans to the target application server.

The sample includes these key features:

Java EE rule sessions
Stateless EJB3 sessions
Package Enterprise JavaBeans (EJB) components and Java EE applications to use Decision Server
Ruleset archives (.dsar files)
A Java XOM (execution object model) for the shop model
Execution report: IlrExecutionTrace
