Apache Tomcat: Enabling Scripting Languages in JSPs

The Java Server Page (JSP) technology allows Java programmers to write webserver applications by injecting Java code into HTML or XML pages which then get translated into Java programs, compiled and executed each time a client request refers to that JSP. This presentation introduces a new taglib which makes it possible to use any Java scripting language (exploiting either the Java scripting framework or the Apache Bean Scripting framework) in JSPs in addition to or instead of Java thereby serving client requests in the client's request thread. The taglib allows among other things to fetch the script code from files and invoke such programs with the servlet's service method arguments (request and response).
