Calling PL/SQL function from external Java class

Question

I was wondering if I was able to call a pl/sql function from an external java class? If so, would you be able to tell me briefly on how to go about it. I know I can call java methods that are internally stored in the db from pl/sql, but I was hoping I could call pl/sql from external java. Thanks,
Kelly

Ok, I made the changes, but I'm now getting the following error:
Error code = 1403
Error message = ORA-01403: no data found
ORA-06512: at "IOBOARD.GETSTATUS", line 6
ORA-06512: at line 1
The ora-01403 I don't understand because there is data for the name Kelly.Brace.
ora-06512 error: at string line string.
Here's what the code looks like after I made the changes:
String sql = "{?=call ioboard.GetStatus(?)}";
      // create a Statement object
      myStatement = myConnection.prepareCall( sql );
      myStatement.setString( 1, "Kelly.Brace" );
      myStatement.registerOutParameter(2, java.sql.Types.LONGVARCHAR );
      // create a ResultSet object, and populate it with the
      // result of a SELECT statement
      ResultSet myResultSet = myStatement.executeQuery();
      // retrieve the row from the ResultSet using the
      // next() method
      myResultSet.next();
      // retrieve the user from the row in the ResultSet using the
      // getString() method
      String status = myResultSet.getString(1);
      System.out.println("Hello Kelly, your status is: " + status);
      // close this ResultSet object using the close() method
      myResultSet.close();Here's what the function looks like:
CREATE OR REPLACE FUNCTION GetStatus( user_name in varchar2)
RETURN VARCHAR2
is
v_status varchar2(10);
BEGIN
select iob_location into v_status
from ioboard.iob_user
where iob_username = user_name;
  RETURN( v_status);
END;This works perfectly in the SQL Window:
select iob_location
from ioboard.iob_user
where iob_username = 'Kelly.Brace';
