Ok perfect, will do that. Used the ResultSaver class for reference to get
familiar with plugin development,

Great, will do. Not sure why it was looking for the default org.apache
package. The code was originally in org.apache, but then moved to a new one,
re-archived the jar in lib/ext (with JMeter closed) and then started JMeter
again. possibly cached classes somewhere?

Table creation.

Users may wish to use Derby or Oracle or some other database.

So long as the appropriate column names and types are created, the
rest of the code should then work with any JDBC database.

JMeter does not cache classes between runs.
