Jakarta Expression Language

Jakarta Expression Language (JEXL) is a scripting and template engine for Java. JEXL allows embedding expressions in text without the need to compile Java code. This expression language simplifies development by providing an easy-to-use syntax that lets developers access objects and perform operations within templates or scripts. It was originally part of the Jakarta project, which encompassed several open-source technologies related to enterprise application development under Apache before being rebranded as Jakarta EE.
