JGeometry and SDO_BUFFER of geodetic coordinates

Question

I can successfully execute SQL that will create a "circle" around a geodetic lat/long using the SDO_BUFFER. The goal is to persist the resulting "circle" that SDO_BUFFER calculates. However, even using JGeometry, I still get the error "Too Many Values" when inserting over JDBC.
How can I execute the following SQL via JDBC? I'm using the JGeometry to "wrap" the point; however, I don't see how to use SDO_BUFFER.
The following is the prepared statement:
insert into t1 (?, ?, SDO_GEOM.SDO_BUFFER(?), ?, ?, ?, ?, ?)
// create a JGeometry for the point reprenting the lat/long
JGeometry landmarkGeo = JGeometry.createPoint(new double[]{latLong.getLongitude(), latLong.getLatitude()}, JGeometry.GTYPE_POINT, 8307);
STRUCT struct = JGeometry.store(landmarkGeo, conn);
stmt.setObject(3, struct);

Answer 1

Your call to sdo_buffer is not correct (syntax error), so it ends up
sending too many values to the table.
> insert into t1 (?, ?, SDO_GEOM.SDO_BUFFER(?), ?, ?, ?, ?, ?)
This closing ")" for sdo_buffer is not in the right place.
Depending on which signature you are using for buffer, move
the ")" to the right place.
How many columns are there in your table ?
