So the JDBC component basically assumes the body of the message is the
SQL to execute.

If you want to query/poll a database and send messages on you could
use the JPA component...

which does exactly that. The idea is you write a JPA entity bean for
the table you want to poll; then when the message is processed, the
row is deleted. (You can use queries and update the entity when its
finished if you prefer).

Another option if you are more comfortable with iBatis than
hibernate/openjpa/toplink is to use the ibatis component...

in both cases the idea is generally to make a bean to represent a row.

We could write an SDO component and use that to avoid the user having
to write a bean...
