Spring Framework & BIRT
By Jason Weathersby and Josh Long Introduction Eclipse’s Business Intelligence and Reporting Tools (BIRT) project is an open-source project based on the popular Eclipse IDE. The BIRT project had its first major release in the summer of 2005 and has garnered over ten million downloads since its inception.Solr TM is the popular, blazing fast open source enterprise search platform from the Apache Lucene TM project. Its major features include powerful full-text search, hit highlighting, faceted search, near real-time indexing, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly reliable, scalable and fault tolerant, providing distributed indexing, replication and load-balanced querying, automated failover and recovery, centralized configuration and more. Solr powers the search and navigation features of many of the world's largest internet sites. Solr is written in Java and runs as a standalone full-text search server within a servlet container such as Tomcat.
Welcome to Solr
Lucene - Overview
Apache Lucene TM is a high-performance, full-featured text search engine library written entirely in Java. It is a technology suitable for nearly any application that requires full-text search, especially cross-platform.Commons Logging - Overview
The Logging Component When writing a library it is very useful to log information. However there are many logging implementations out there, and a library cannot impose the use of a particular one on the overall application that the library is a part of. The Logging package is an ultra-thin bridge between different logging implementations.
End of life The Commons HttpClient project is now end of life, and is no longer being developed. It has been replaced by the Apache HttpComponents project in its HttpClient and HttpCore modules, which offer better performance and more flexibility. Introduction The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant protocol used on the Internet today.

Commons Collections The Java Collections Framework was a major addition in JDK 1.2. It added many powerful data structures that accelerate development of most significant Java applications. Since that time it has become the recognised standard for collection handling in Java. Commons-Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities.

Commons Chain - Overview
Commons Chain A popular technique for organizing the execution of complex processing flows is the "Chain of Responsibility" pattern, as described (among many other places) in the classic "Gang of Four" design patterns book. Although the fundamental API contracts required to implement this design patten are extremely simple, it is useful to have a base API that facilitates using the pattern, and (more importantly) encouraging composition of command implementations from multiple diverse sources. Towards that end, the Chain API models a computation as a series of "commands" that can be combined into a "chain". The API for a command consists of a single method ( execute() ), which is passed a "context" parameter containing the dynamic state of the computation, and whose return value is a boolean that determines whether or not processing for the current chain has been completed (true), or whether processing should be delegated to the next command in the chain (false).
Commons CLI The Apache Commons CLI library provides an API for parsing command line options passed to programs. It's also able to print help messages detailing the options available for a command line tool. Commons CLI supports different types of options: POSIX like options (ie. tar -zxvf foo.tar.gz ) GNU like long options (ie. du --human-readable --max-depth=1 ) Java like properties (ie. java -Djava.awt.headless=true -Djava.net.useSystemProxies=true Foo ) Short options with value attached (ie. gcc -O2 foo.c ) long options with single hyphen (ie. ant -projecthelp ) A typical help message displayed by Commons CLI looks like this:

BeanUtils - Commons
Commons BeanUtils Most Java developers are used to creating Java classes that conform to the JavaBeans naming patterns for property getters and setters. It is natural to then access these methods directly, using calls to the corresponding getXxx and setXxx methods.
Axis2 - Apache Axis2/Java - Next Generation Web Services
Apache Axis2™ is a Web Services / SOAP / WSDL engine, the successor to the widely used Apache Axis SOAP stack. There are two implementations of the Apache Axis2 Web services engine - Apache Axis2/Java and Apache Axis2/C While you will find all the information on Apache Axis2/Java here, you can visit the Apache Axis2/C Web site for Axis2/C implementation information.Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new . You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts.
guice - Guice (pronounced 'juice') is a lightweight dependency injection framework for Java 5 and above, brought to you by Google.
Articles Index The major theme of version 5 of the Java Platform, Enterprise Edition (Java EE, formerly referred to as J2EE) is ease of development. Changes throughout the platform make the development of enterprise Java technology applications much easier, with far less coding. Significantly, these simplifications have not changed the platform's power: The Java EE 5 platform maintains all the functional richness of the previous version, J2EE 1.4.
