This includes applications of Java EE applications (based on application servers), the application of java-based desktop applications, and Java Webstart methods.

IK expression was originally born to enhance the flexibility of the workflow engine, such as JBPM, for process configuration. Make it possible to change the execution logic condition as flexibly as the configuration period during the process run time. The extended IK expression can also be applied to dynamic condition configurations for a variety of conventional business systems, such as situations where graphical configuration applications are required, or scenarios that simulate formula operations for Excel spreadsheets.
