AxisApache Axis is an implementation of the SOAP ("Simple Object Access Protocol") submission to W3C.
CastorCastor is an Open Source data binding framework for Java[tm]. It's the shortest path between Java objects, XML documents and relational tables. Castor provides Java-to-XML binding, Java-to-SQL persistence, and more.
DWRDWR allows Javascript in a browser to interact with Java on a server and helps you manipulate web pages with the results.
FCKEditorThis HTML text editor brings to the web much of the power of desktop editors like MS Word. It's lightweight and doesn't require any kind of installation on the client computer.
HibernateHibernate is an object-relational mapping (ORM) library for the Java language, providing a framework for mapping an object-oriented domain model to a traditional relational database. Hibernate solves Object-Relational impedance mismatch problems by replacing direct persistence-related database accesses with high-level object handling functions.
HypersonicSQLHSQLDB is the leading SQL relational database engine written in Java. It has a JDBC driver and supports a rich subset of ANSI-92 SQL (BNF tree format) plus SQL 99 and 2003 enhancements. It offers a small (less than 100k in one version for applets), fast database engine which offers both in-memory and disk-based tables and supports embedded and server modes. Additionally, it includes tools such as a minimal web server, in-memory query and management tools (can be run as applets) and a number of demonstration examples.
IBatisThe iBATIS Data Mapper framework makes it easier to use a database with Java and .NET applications. iBATIS couples objects with stored procedures or SQL statements using a XML descriptor. Simplicity is the biggest advantage of the iBATIS Data Mapper over object relational mapping tools.
iTextThis library contains classes that generate documents in the Portable Document Format (PDF) and/or HTML.
JetspeedJetspeed is an Open Source implementation of an Enterprise Information Portal, using Java and XML.
Log4JWith log4j it is possible to enable logging at runtime without modifying the application binary. The log4j package is designed so that these statements can remain in shipped code without incurring a heavy performance cost. Logging behavior can be controlled by editing a configuration file, without touching the application binary.
LuceneApache Lucene 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.

Although the Spring Framework does not enforce any specific programming model, it has become popular in the Java community as an alternative, replacement, or even addition to the Enterprise JavaBean model. By design, the framework offers a lot of freedom to Java developers yet provides well documented and easy-to-use solutions for common practices in the industry.
TomcatApache 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.
TorqueTorque is an object-relational mapper for java. In other words, Torque lets you access and manipulate data in a relational database using java objects.
TurbineTurbine is a servlet based framework that allows experienced Java developers to quickly build web applications. Turbine allows you to use personalize the web sites and to use user logins to restrict access to parts of your application.
