Feed4TestNG makes it easy to write parameterized tests for the TestNG framework and feed them with predefined or randomly generated test data: test case data can be read from Excel or CSV files and equivalence class tests can be defined easily. Setup is based on Java annotations and easy to learn, apply, and maintain. Annotations defined in the "Bean Validation" JSR 303, Java 7 and Benerator are automatically recognized and generated smoke test data will match the constraints. By connecting to Benerator, you can configure generation of complex valid and invalid data sets.
Netbeans Java SQL Generator is a plugin that automatically generates SQL code (currently for MySQL and PostgreSQL) and Java database methods (such as insertIntoTable, update, delete, and createTable) from variables in a Java class. It comes with many options and possibilities to customize the generated SQL and code for your needs. It works with Netbeans version 6.9 or later on any Netbeans supported system.
SerfJ provides a very easy way of developing Java REST Web applications. It helps you to develop your application over an elegant MVC architecture, giving more importance to convention than configuration. This means, for example, you will not need configuration files or annotations in order to specify which view serves a controller's method. However, SerfJ is very flexible, so if you want to jump over those conventions, you can configure the behavior of your applications as you like. The framework tries to meet the JSR 311 specification, but it doesn't follow every point of the specification, because the purpose is to have a very intuitive library, and some some aspects of the specification are out of the scope of SerfJ.
