Installing Rule Designer
You must install Rule Designer into an existing instance of Eclipse. As a rule developer, you work in Rule Designer to create decision services that use rules to implement your business logic.
You can install Rule Designer online or offline. After you install it, you set up its security.
You install Rule Designer into Eclipse 2023-12. Use at least Eclipse Modeling Tool or Eclipse IDE for Enterprise Java and Web Developers.
Eclipse 2023-12 uses Java Development Kit (JDK) 17. You can download the JDK from IBM Semeru Runtimes Downloads.
If you install Rule Designer in an Eclipse
environment that does not use an English locale:
- The Eclipse messages remain in the language of your Eclipse environment.
- If Rule Designer provides the verbalizer for the language, you can create rule artifacts in this language. If a verbalizer for this language does not exist, the rule artifacts that you create are in English.
- Rule Designer messages appear in the locale if it is supported. Otherwise, they appear in English.
- To change the locale so that everything is in English, add the osgi.nl=en_US property to the <Eclipse_InstallDir>/configuration/config.ini file, and then restart Rule Designer.
Using this installation of Rule Designer you can:
- Write a Java™ XOM that references XOM annotations and the decision engine API. For more information, see Adding annotations to the XOM.
- Run and debug decision operations. For more information, see Running and debugging decision operations.
Restriction: You cannot generate a Java client
project to run rulesets through the rule engine API or the Rule Execution Server API.
