I use it for configuration purposes.

I wrote a JdbcSupport API latelty, that does automatic bean mapping for a ResultSet.

As per convention, I matched the property names of the JavaBeans to the columns. For example:



would map to the sql columns firstName and lastName.

If these however do not match, for instance if the sql columns are names first_name and last_name, I used an annotation for the mapping:



I don't know if that is the best example, but I hope it makes it clear a bit.

Welcome to JavaRanch.

See Annotations in Sun's Java Tutorials.
