Creating a point geometry with coordinate transformation using JDBC

Question

If I execute the following SQL statement using a tool such as TOAD then I get a correct value for the point in the oracle column.
INSERT INTO node (id, position) VALUES (53, SDO_CS.TRANSFORM(SDO_GEOMETRY(2001, 26910, SDO_POINT_TYPE(489535.0, 5457841.0, NULL), NULL, NULL), 4269))
Point geometry:
(2001, 4269, (-123.143865452971, 49.2732377100255, ), , )
If I execute the same statement using JDBC in a Statement or PreparedStatement the Point in the oracle column has 0,0 for the coordinates.
Point: geometry
(2001, 4269, (0, 0, ), , )
In both cases the SQL is exactly the same.
my JDBC code is
String insertSql = "INSERT INTO node (id, position) VALUES (" + id
+ ", SDO_CS.TRANSFORM(SDO_GEOMETRY(2001, " + geometrySrid
+ ", SDO_POINT_TYPE(" + coordinate2d.x + ", " + coordinate2d.y
+ ", NULL), NULL, NULL), " + srid + "))";
Statement insertStatement = connection.createStatement();
try {
insertStatement.execute(insertSql);
} finally {
JdbcUtils.closeStatement(insertStatement);
connection.commit();
Any ideas why this is happening?
I've tried to do the coordinate transformation in a separate call and pass in the STRUCT returned from that, using JGeometry to create a STRUCT for the value, using a WKT geometry and none of these approaches seem to work

Paul,
I have seen this work using JGeometry and STRUCT objects with PreparedStatements. Here's some sample code that seems to work just fine:
ResultSet rs = null;
try {
PreparedStatement ps =
getConn().prepareStatement("select SDO_CS.TRANSFORM(?, ?) from dual");
/* constucts JGeometry objects using simple points (doubles) and SRID
* Per the Javadoc, JGeometry objects can be constructed using the same
* notation and signature as SDO_GEOMETRY objects -
* JGeometry(int gtype, int srid, double x, double y, double z, int[] elemInfo, double[] ordinates) */
JGeometry j_geom1 = new JGeometry(-122.4, 37.8, 8265);
int newSRID = 4269;
//convert JGeometry instances to DB STRUCT
STRUCT obj1 = JGeometry.store(j_geom1, getConn());
ps.setObject(1, obj1);
ps.setInt(2, newSRID);
rs = ps.executeQuery();
while (rs.next()) {
//System.out.println(rs.getString(1));
STRUCT st = (oracle.sql.STRUCT) rs.getObject(1);
JGeometry j_geom = JGeometry.load(st);
System.out.println(j_geom);
ps.close();
rs.close();
conn.close();
} catch (Exception e) {
System.err.print(e);
Hope this helps.
