Many Apache projects support interaction with a relational database. Creating a new connection for each user can be time consuming (often requiring multiple seconds of clock time), in order to perform a database transaction that might take milliseconds. Opening a connection per user can be unfeasible in a publicly-hosted Internet application where the number of simultaneous users can be very large. Accordingly, developers often wish to share a "pool" of open connections between all of the application's current users. The number of users actually performing a request at any given time is usually a very small percentage of the total number of active users, and during request processing is the only time that a database connection is required. The application itself logs into the DBMS, and handles any user account issues internally.
ECJ is the the Eclipse Compiler for Java. It is also known as the JDT Core batch compiler.
systemd is a system and service manager that runs as PID 1 and starts the rest of the system.
JSON.simple is a simple Java toolkit for JSON. You can use JSON.simple to encode or decode JSON text. * Full compliance with JSON specification (RFC4627) and reliable * Provides multiple functionalities such as encode, decode/parse and escape JSON text while keeping the library lightweight * Flexible, simple and easy to use by reusing Map and List interfaces * Supports streaming output of JSON text * Stoppable SAX-like interface for streaming input of JSON text * Heap based parser * High performance (see performance testing) * No dependency on external libraries * Both of the source code and the binary are JDK1.2 compatible
Apache Hadoop is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. This package provides a server that provides HTTP REST API support for the complete FileSystem/FileContext interface in HDFS.
Apache Servlet/JSP Engine, RI for Servlet 4.0/JSP 2.3 API
Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process. Tomcat is developed in an open and participatory environment and released under the Apache Software License version 2.0. Tomcat is intended to be a collaboration of the best-of-breed developers from around the world.
JNI wrappers for Apache Portable Runtime for Tomcat
Tomcat can use the Apache Portable Runtime to provide superior scalability, performance, and better integration with native server technologies. The Apache Portable Runtime is a highly portable library that is at the heart of Apache HTTP Server 2.x. APR has many uses, including access to advanced IO functionality (such as sendfile, epoll and OpenSSL), OS level functionality (random number generation, system status, etc), and native process handling (shared memory, NT pipes and Unix sockets). These features allows making Tomcat a general purpose webserver, will enable much better integration with other native web technologies, and overall make Java much more viable as a full fledged webserver platform rather than simply a backend focused technology.
