Sequoia provides high availability and performance scalability for databases. It is is the continuation of the C-JDBC project. It provides transparent database clustering (partitioning, replication, etc.). It works with any Java application without code modification and with any database engine. It has been successfully tested with Tomcat, JBoss, JOnAS, WebSphere, MySQL, PostgreSQL, Apache Derby, HSQLDB, SAP DB, Oracle, DB2, Sybase, MS SQL Server, Firebird, and more.
Expresso Framework is an open standards-based J2EE architectural framework that allows the developer to concentrate on application logic. It is a library of extensible Java Server application framework components for creating database-driven Web applications based on open standards. Expresso integrates with Apache Jakarta Struts, which emphasizes presentation and application configuration, and bringing a powerful tag library to Expresso. Expresso adds capabilities for security, robust object-relational mapping, background job handling and scheduling, self-tests, logging integration, automated table manipulation, database connection pooling, email connectivity, event notification, error handling, caching, internationalization, XML automation, testing, registration objects, configuration management, workflow, automatic database maintenance, and a JSP tag library.
Velocity is a Java-based template engine. It permits anyone to use the simple yet powerful template language to reference objects defined in Java code. When Velocity is used for Web development, Web designers can work in parallel with Java programmers to develop Web sites according to the Model-View-Controller (MVC) model, meaning that Web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the Web pages, making the web site more maintainable over the long run and providing a viable alternative to Java Server Pages (JSPs) or PHP. Velocity also provides template services for the Turbine Web application framework, making a template service that allows Web applications to be developed according to a true MVC model.
The Java Application Monitor (JAMon) is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications. JAMon can be used to determine application performance bottlenecks, user/application interactions, and application scalability. JAMon gathers summary statistics such as hits, execution times (total, average, minimum, maximum, standard deviation), and simultaneous application requests. JAMon statistics are displayed in the sortable JAMon report.
jPersist is an extremely powerful object-relational database persistence API that manages to avoid the need for configuration and annotation; mapping is automatic (A-O/RM). It uses JDBC, and can work with any relational database and any type of connection resource. It uses information obtained from the database to handle mapping between the database and Java objects, so mapping configuration is not needed, and annotation is not needed. In fact, there is no configuration needed at all.
Uncle Unc is a framework for working with trees of objects. Existing services such as filesystems, code libraries, networks, log files, mailboxes and directories can be mapped onto this object tree, as can some traditional desktop applications. User interfaces work directly with the object tree, offering best of breed interface design (e.g. filtering, breadcrumb bars, paging, sorting, and file-explorer-like views) across the full range of services. The framework promotes clean design, completeness of representation, and reusability of both front end and back end code.
Atris Framework is a fully functional platform independent GUI framework based on the Java/Swing API. It provides an advanced GUI screen editor with features including an abstract data layer, pre-built Design Patterns, data set to visual component mappings, window management (tiling, last position/size memory), database/app server login control, preference management, advanced table and tree management, advanced data relationship management, automated management of standard CRUD operations, launching GUI applications from Web sites directly, table sorting, column ordering, table searching, in-table editing, and the ability to import existing visual components in addition to many other features.
Liberty Data Base Connectivity is a JDBC driver that provides vendor-independent database access. With LDBC, applications will just work on all major databases without source code changes. It is based on ANSI SQL and JDBC. It is very easy to use and learn, small and fast, and based on standards.
