Object-Graph Navigation Language (OGNL) is an open-source Expression Language (EL) for Java, which, while using simpler expressions than the full range of those supported by the Java language, allows getting and setting properties (through defined setProperty and getProperty methods, found in JavaBeans), and execution of methods of Java classes.
Создан OGNL Technology как язык выражений () для языка Java, который позволяет манипулировать свойствами (через JavaBeans методы "setProperty" и "getProperty"), и обращаться к методам классов Java.
