-----------------------------------------------------------

+1 for using lightweight db library instead of JPA which is overkill for this. Using JDBC directly is very painful. There is also Spring's jdbcTemplate, although downside is we have to add a big Spring dependency.

[~sharadag] We are already using Apache dbutils in lens server module. Would that be sufficient? Otherwise we have two different libraries for the same purpose in different modules.
