Java EE LoadBalancer Project on java.net The Java EE LoadBalancer Filter is a pure J2EE Web Component for high traffic environments. Java Server Performance depends on CPU & Memory allocation of Traffic. Tuning Performance is also a borderline Process in reference to stability. Java EE LoadBalancer addresses this with Monitoring and Run-time Customizing of key parameters (response time & throughput). Traffic is directed among a Semaphore mechanism[from E.W.Dijkstra] to protect memory critical resources. Fail-over strategies are implemented and customizable while calibration process. Via jconsole essential Visibility into Java Web Transactions is supported across your Web Application infrastructure. You can identify performance problems and balance your Java Web Server. The LoadBalancer can be easily deployed over loadbalancer.jar registration in Web-Inf/lib directory of the Web Application and administrated in every Web Application using web.xml registration and configuration. The LoadBalancer runs on all Java Web Containers without any modification and requires a Servlet Specification 2.3 or later. The LoadBalancer supports HTTP and JMX Monitoring and JMX Run-time Customizing of LoadBalancer Parameters. Historical Profiling is supported via file logging using the java.util.logging facility. Using this loadbalancing practice is no hardware or software architecture changes required.

The complete segregation of a script's variables from those in the lexical scope of the embedding Java program greatly hinders the use of scripting languages in large-scale applications. This article describes the use and development of "InScript" -- a tool that enables embedded scripts in any JSR-223 language to read and write Java variables naturally, without requiring manually programmed "put()"s and "get()"s to move values to and from the script engine. The freedom to use Java variables in scripts makes it easy to customize programs, or even implement large portions of programs, with scripts.
The term "first-class function" is now very well-known, partly because of the renewed interest in functional-programming languages (Scala, Clojure, Erlang, etc.). But a quick google search shows that the only well-known meaning of "first-class code" is a category of airline travel that includes "Supersonic or First Class Suite (currently only on the Airbus A380)"! Well, for the purposes of this article, script embedded in a Java program is not "first-class code" because it can not use in-scope Java variables unless the variables have been put into the script engine by explicit program action. This article describes the use and development of "InScript" -- a tool that enables scripts in any JSR-223 supported language to use in-scope variables from the embedding Java program naturally -- without the need for any manually programmed action on the Java variables.
