Error calling StoredProcedure with parameters (3 replies)

I have set up a new MySql database and defined a test stored procedure. I can call stored procedures that take no parameters, but if I call one that takes at least one parameter I get an index exception.

       Connection c = connector.getConnection();
       CallableStatement cs = c.prepareCall("{ call fms.OneParam(?)}");
       cs.registerOutParameter(1, java.sql.Types.INTEGER);
       cs.execute();   <== FAILS WITH SQLException
       int param1 = cs.getInt(1);
       return param1;

The exception I receive is the following:

java.sql.SQLException Parameter index of 1 is out of range (1, 0)

The stored procedure looks like:

CREATE DEFINER=`root`@`localhost` PROCEDURE `OneParam`(
        OUT ecode INT)
BEGIN

 SET ecode = 5;

END

And the user I am connecting with has execute permissions on the stored procedures.

Additional info:
1) Installed using xampp
2) Using MySql 5.5

More Info
-----------
I noticed that if I go into MySql Admin and look at the stored procedures as 'root' everything is fine. But if I log in as 'webuser' I cannot see the body of the stored procedures. I have assigned ALL privileges to the user, but he still cannot see the body. I exported the database and changed the creator to 'webuser' restored the database and still could not see the procedure body as 'webuser'.

Yet More info
-------------
I have removed the calls to the stored procedures and put the SQL directly in my code and I still get the same error message.

      Connection c = null;
      PreparedStatement ps = null;
      try {
         c = connector.getConnection();
         ps = c.prepareStatement(INSERT_USER_REC);
         ps.setString(1, reginfo.getLicKey());
         ps.setString(2, reginfo.getEmailAddress().toString());
         ps.setString(3, reginfo.getFirstName());
         ps.setString(4, reginfo.getLastName());
         int rtn = ps.executeUpdate();
      } finally {
         if (c != null) { connector.closeConnection(c); }
         if (ps != null) { ps.close(); } // also closes the result set
      }
