Answer 1

You must register the input/output parameters like this and then call stored procedure/function
CallableStatement cstStat = this.con.prepareCall("{? = call some_package.some_function(?) }");
cstStat.registerOutParameter(1, java.sql.Types.VARCHAR);
cstStat.setString(2, Name);
int res = cstStat.executeUpdate();
String outParam = cstStat.getString(1);
