ATG Dynamo integration for JBuilder is a JBuilder 5 plugin that makes it easy to deploy J2EE applications to the ATG Dynamo Application Server version 5.1 (DAS). It can be installed and run with the other JBuilder 5 plugins such as BEA WebLogicServer 5.1, BEA WLS 6, IBM WebSphere 3.5, Borland AS 4.5, etc.
Jatha is a macro preprocessor for Java. It's different from most macro systems because it doesn't just perform textual substituation the way C macros do; instead, in Jatha, each macro is processed by custom Java code that you write yourself. It allows you to have very smart macros. You can put Jatha macros inside any kind of file--Java source files, C++ source files, plain text, etc. Jatha is not intended for use in Web sites or HTML, because it is not designed to do macro expansions whenever a page is requested.
Admin is entirely written in Java. It uses Swing GUI Components and JDBC to connect to databases. It has been succesfully tested with MySQL, Derby, InstantDB, Oracle, Empress, MS SQL Server, and PostgreSQL. You can have a tree view of the RDBMS or pick a single instance to have a look at its metadata. It allows you to create, modify, and drop tables and to create indices on a table. The dynamic form makes it easy to enter data into a certain table, and the guided query makes it easy to retrieve data from a table and to export it. Java developers will probably enjoy the code generator doing an OO relational wrapper and a swing GUI for them. There is a tool with which SQL statements can be enriched with a few commands, generating a GUI to easily select data from a DB. You can also export and import data and transport it from one DBMS to another.
GNU Lightning is a library that generates assembly language code at run time. It is very fast, making it ideal for Just-In-Time compilers, and it abstracts over the target CPU, as it exposes to the clients a standardized RISC instruction set (inspired by the MIPS and SPARC chips).
