Apache Tomcat: Enabling Scripting Languages in JSPs
summary
A JSP taglib implements a JSR-223 taglib for JSP that lets any javax.script or BSF engine run as if it were a servlet, receiving request, response and out; it loads scripts from files with caching/compilation options and emits detailed debug bindings. It runs under works on Tomcat 9 and 10 (javax vs jakarta namespaces), the provided demo WAR with SQLite inserts from Rex, JavaScript, Groovy, Jython, PHP shows cross-language sharing of a DB connection, and a known Jython argument bug requires arguments="false".
