rsmapper RS-Mapper simple ORM

RS Mapper is a Java library to provide JDBC operations just like complex ORMs like Hibernate. But in much simplier way. It's also alternative for Spring JdbcTemplate but RS Mapper is a bit richer because JDBC operations can construct populated entity objects without need to write ResultSet.getObject or PreparedStatement.setObject calls.
