Older MySQL JDBC Driver issues with INSERT, UPDATE, DELETE

I haven’t worked on my wife’s recipe site in ages. Originally written as an experiment with JSP and Java, I think my mom and Karen are the only people that use it (which is fine with me). In any case, I recently moved it to a new host and saw a weird issue pop up in catalina.out where any INSERT, UPDATE or DELETE statements were erroring out with the message:

java.sql.SQLException: Can not issue data manipulation statements with executeQuery()

Turns out that earlier versions of the MySQL JDBC driver allowed you to run INSERT / UPDATE / DELETE statements using the executeQuery() method of the PreparedStatement class, which violated the JDBC specification, but worked nonetheless. The newer versions are JDBC compliant and don’t allow that behavior, which causes the above mentioned SQL exception. More from the MySQL forums.
