CallableStatement does not run PL/SQL with jdbc:oracle:thin driver

Question

I have a very simple PL/SQL function:
FUNCTION CalculateDistance
(x1 IN NUMBER, y1 IN NUMBER, x2 IN NUMBER, y2 IN NUMBER)
RETURN NUMBER
AS
distance NUMBER;
BEGIN
distance := SQRT(POWER(x1-x2,2) + POWER(y1-y2,2));
return distance;
END;
I call it with:
CallableStatement cs = null;
try {
biomassStatement = con.prepareCall("{ call MYPACKAGE.CalculateDistance(?, ?, ?, ?, ?)}");
cs.setDouble("X1", -367546.78402892);
cs.setDouble("Y1", 150712.8161204);
cs.setDouble("X2", -2155095.49289);
cs.setDouble("Y2", 774013.149084);
cs.registerOutParameter("v_Return", OracleTypes.NUMBER);
cs.execute();
The only answer I get is:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'CALCULATEDISTANCE'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
I tried it with different Data sources (common, pool, XA) and nothing works...
Tried using ojdbc14_g.jar to see if could get more information with no help...
HELP!!!

Answer 1

Hi,
You are calling a FUNCTION, i.e you have one return value (And four arguments)
So according to javadocs
http://download.oracle.com/javase/6/docs/api/java/sql/CallableStatement.html
Your synbtax should be like:
{?= call <procedure-name>[(<arg1>,<arg2>, ...)]}Rigtht now, your call seems to be for a procedure having five arguments.
