ParameterNotBound exception when using reflection to set params

Question

I'm using the JDBC type 4 thin driver going to 8.1.6 on Win2K.
I have an EJB method that uses reflection to do the set<type> methods on the PreparedStatement to set the positional parameters for a SQL query statement.
The first time the method executes, I get a ParameterNotBound exception. I've used the debugger to determine that all the parameters are bound - at least the set<type> methods have been called.
The wierd thing is that all subsequent calls to the the SQL query method work fine.
Does anyone here know where in the PreparedStatement class are the parameters bound. What data element? I'm trying use the debugger to determine what's different the first time the method is called.
Thanks,
Rich Bolen

Congrats Darek!
That function really works... here is my program test:
package integracao.sap.teste;
import java.util.Properties;
import integracao.sap.config.ConfigUtil;
import integracao.sap.funcao.RFC_READ_TABLE;
import com.sap.mw.jco.IRepository;
import com.sap.mw.jco.JCO;
public class TestJCOError {
     private static Properties config;
     private static JCO.Client createJCOClient(){
          JCO.Client client = JCO.createClient(config.getProperty("numClient"), config.getProperty("user"), config.getProperty("password"), "EN", config.getProperty("host"), config.getProperty("numPrograma"));
          return (client);
@param args
     public static void main(String[] args) {
          config = ConfigUtil.getConfig();
          JCO.Client client = createJCOClient();
          client.connect();
          IRepository repository = JCO.createRepository("REP", client);
          JCO.Function func = RFC_READ_TABLE.createFunction(repository);
          func.getImportParameterList().setValue("MARC", "QUERY_TABLE");
          func.getImportParameterList().setValue(";",    "DELIMITER");
          func.getTableParameterList().getTable("OPTIONS").appendRow();
          func.getTableParameterList().getTable("OPTIONS").setValue("MATNR = '000000000000000011'", "TEXT");
          func.getTableParameterList().getTable("FIELDS").appendRow();
          func.getTableParameterList().getTable("FIELDS").setValue("MATNR", "FIELDNAME");
          client.execute(func);
          JCO.Table table = func.getTableParameterList().getTable("DATA");
          System.out.println("NumRows: " + table.getNumRows());
          System.out.println("Content: " + table.getValue("WA"));
Result:
NumRows: 1
Content: 000000000000000011
Hope it helps everybody!
