ActiveJDBC

ActiveJDBC is a Java implementation of the Active Record design pattern developed by Igor Polevoy. It was inspired by ActiveRecord ORM from Ruby on Rails. It is based on convention over configuration.

Writing models

Similar to Ruby on Rails, ActiveJDBC infers metadata from a database. The result is that models do not require setters and getters.

Creation of and saving new records in a table:

Employee e = new Employee();
e.set("first_name", "John");
e.set("last_name", "Doe");
e.saveIt();

or the same on one line:

Employee.createIt("first_name", "John", "last_name", "Doe");

And for updating an existing record:

Employee e = Employee.findFirst("first_name = ?", "John");
e.set("last_name", "Steinbeck").saveIt();

ActiveJDBC does not have a query language. Search criteria are written in abbreviated SQL.

List<Employee> employees = Employee.where("first_name = ?", "John");

While ActiveJDBC is a general purpose Java ORM, it served as a first building block for JavaLite.
