Viewobject - Stored Procedure with sys_refcursor out

Question

Hi,
I have been trying to call an Oracle stored procedure which returns sys_refcursor as an out parameter.
Even though I register out parameter in callStoreFunction method, I am getting "PLS-00306: wrong number or types of arguments in call".
You can find piece of codes below.
Could you please help?
Thanks in advance.
Stored Procedure;*
CREATE OR REPLACE PROCEDURE SP_GET_PRODUCT_DETAIL_BY_ID(
ID_in IN NUMBER,
p_product_refcur OUT SYS_REFCURSOR
IS
BEGIN
OPEN p_product_refcur FOR SELECT * FROM PRODUCT_DETAIL WHERE ID = ID_in;
END SP_GET_PRODUCT_DETAIL_BY_ID;
Java Code*
The code that calls function method;
ResultSet rs = (ResultSet)callStoredFunction(OracleTypes.CURSOR,"SP_GET_PRODUCT_DETAIL_BY_ID(?)",new Object[]{new Number(3)});
Call function method;
protected Object callStoredFunction(int sqlReturnType, String stmt, Object[] bindVars) {
CallableStatement st = null;
try {
System.out.println("222222");
// 1. Create a JDBC CallabledStatement
st = getDBTransaction().createCallableStatement("begin ? := " + stmt + ";end;", 0);
// 2. Register the first bind variable for the return value
st.registerOutParameter(1, sqlReturnType);
if (bindVars != null) {
// 3. Loop over values for the bind variables passed in, if any
for (int z = 0; z < bindVars.length; z++) {
// 4. Set the value of user-supplied bind vars in the stmt
st.setObject(z+2, bindVars[z]);
// 5. Set the value of user-supplied bind vars in the stmt
st.executeUpdate();
// 6. Return the value of the first bind variable
return st.getObject(1);
} catch (SQLException e) {
e.printStackTrace();
throw new JboException(e);
} finally {
if (st != null) {
try {
// 7. Close the statement
st.close();
} catch (SQLException e) {
e.printStackTrace();
}

Hi mate,
Sorry about that. My Jdev version is 11.1.2.3.0.
The use case is that I am trying to call a SP from a VO which is triggered from App Module. I have a bind parameter in App Module for SP input, but at the moment I am using a static value for test purpose.
I am able to make a call from App Module to SP via VO but got an error as I am calling with wrong parameters.
Stored Procedure;_
CREATE OR REPLACE PROCEDURE SP_GET_PRODUCT_DETAIL_BY_ID(
   ID_in IN NUMBER,
   p_product_refcur OUT SYS_REFCURSOR
IS
BEGIN
   OPEN p_product_refcur FOR SELECT * FROM PRODUCT_DETAIL WHERE ID = ID_in;
END SP_GET_PRODUCT_DETAIL_BY_ID;
Java Code_
The code that calls function method;
ResultSet rs = (ResultSet)callStoredFunction(OracleTypes.CURSOR,"SP_GET_PRODUCT_DETAIL_BY_ID(?)",new Object[]{new Number(3)});
Call function method;
protected Object callStoredFunction(int sqlReturnType, String stmt, Object[] bindVars) {
   CallableStatement st = null;
   try {
      // 1. Create a JDBC CallabledStatement
      st = getDBTransaction().createCallableStatement("begin ? := " + stmt + ";end;", 0);
      // 2. Register the first bind variable for the return value
      st.registerOutParameter(1, sqlReturnType);
      if (bindVars != null) {
         // 3. Loop over values for the bind variables passed in, if any
         for (int z = 0; z < bindVars.length; z++) {
            // 4. Set the value of user-supplied bind vars in the stmt
            st.setObject(z+2, bindVars[z]);
      // 5. Set the value of user-supplied bind vars in the stmt
      st.executeUpdate();
      // 6. Return the value of the first bind variable
      return st.getObject(1);
      } catch (SQLException e) {
         e.printStackTrace();
         throw new JboException(e);
      } finally {
         if (st != null) {
            try {
               // 7. Close the statement
               st.close();
            } catch (SQLException e) {
               e.printStackTrace();
The exact error;
java.sql.SQLException: ORA-06550: line 1, column 14:
PLS-00306: wrong number or types of arguments in call to 'SP_GET_PRODUCT_DETAIL_BY_ID'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignoredThanks alot.
