This chapter explains the procedures of using CA Rule Engine in detail, both from the client side and from the rulebase side. Starting with a sample business scenario, this tutorial explains the authoring of RDL rulebase with the infix rule language and the Infix2RDL tool, the use of the WrapperMaker tool to generate the Java classes that wrap the rulebase classes, the addition of session details to the generated template session class and the invocation of inferencing services.
A properly installed CA Rule Engine distribution is required to follow the steps in this tutorial. See Install and Configure CA Rule Engine for more information. In addition, if drag and drop invocation of tool scripts is not used, it is also necessary to add the bin folder of the CA Rule Engine distribution on the PATH. In order to run the resulting application, it is also necessary to make sure the current folder, or “.”, have been put on the CLASSPATH.
All tutorial related files are located in the tutorial folder of the CA Rule Engine distribution kit.
