MyJgui is a GUI (graphical user interface) for MySQL. It aims to be easy to use for new users as well as experts. You can store multiple connections that can be used simultaneously. Stored passwords are encrypted using symmetric encryption. Underlying databases and tables are displayed in a tree structure with the connections being the first level nodes. MyJgui is capable of easy data manipulation through a grid. It has a unique feature of bookmarking parametrical queries (sqlmarks). The documentation (user guide) is quite comprehensive and kept up-to-date.
The goal of the Apache Tomcat Project is to provide commercial-quality server solutions based on the Java Platform that are developed in an open and cooperative fashion. Tomcat 3.x is an implementation of the Java Servlet 2.2 and JavaServer Pages 1.1 Specifications. Tomcat 4.x is an implementation of the Java Servlet 2.3 and JavaServer Pages 1.2 Specifications, and is a re-implementation of the Tomcat servlet engine from the ground up. The current branch, Tomcat 5.x, is an implementation of the Java Servlet 2.4 and JavaServer Pages 2.0 specifications, with increased attention to scalability, reliability, and management functionality.
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.
ProGuard is a shrinker, optimizer, obfuscator, and preverifier for Java bytecode. It detects and removes unused classes, fields, methods, and attributes. It optimizes methods and removes dead code. It renames the remaining classes, fields, and methods using short, meaningless names. Finally, it preverifies the processed code for Java 6 or higher, or for Java Micro Edition. The resulting code is more compact, more efficient, and more difficult to reverse-engineer. Advantages of ProGuard compared to other Java shrinkers and obfuscators are compact template-based configuration, memory efficiency, and speed. It is mostly popular for embedded development and for commercial development, and is integrated in Oracle's Wireless Toolkit, in Intel's TXE SDK, and in Google's Android SDK.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
jEdit is an Open Source text editor written in Java. It has many useful features, such as syntax highlighting, bracket matching, regular expression searching, multiple file search and replace, folding, and keyboard macros. jEdit also includes a powerful plugin architecture that allows more than 80 plugins to be downloaded and installed from within the editor.
