Answer 1

I have the same problem:
Just like in Toystore Demo I am calling the following method in my VO:
   * Find an account by username and password, leaving the account
   * as the current row in the rowset if found. BUT EVEN IF WE FIND ACCOUNT BY
   * USERNAME AND PASSWORD, IT WILL RETURN FALSE IF THE ACCOUNT IS DISABLED!!!!
   * @param username the username
   * @param password the user's password
   * @return whether the user account exists or not
  public boolean findAccountByUsernamePassword(String username, String password) {
     * We're expecting either zero or 1 row here, so indicate that
     * by setting the max fetch size to 1.
    setMaxFetchSize(1);
    setWhereClause("staff_id = :0 and passw = :1");
    setWhereClauseParam(0, username);
    setWhereClauseParam(1, password);
    executeQuery();
    RowSet rs = this.getRowSet();
    String userEnabled = new String("N");  // Default setting
    if (rs != null){
      int currentSlot = rs.getCurrentRowSlot();
      Row r = rs.getCurrentRow();
      if (r == null){
         r=rs.first();
         currentSlot = rs.getCurrentRowSlot();
      //check if we found the user
      if (currentSlot == SLOT_VALID){
        Object[] av = r.getAttributeValues();
        LoginUtils.userLoggedIn    = av[0].toString();  // '0' is username
        LoginUtils.userFirstName   = av[1].toString();  // '1' is user first name
        LoginUtils.userAccessLevel = av[6].toString();  // '6' is user level
        LoginUtils.userEnabled     = av[7].toString();  // '7' is user level
        userEnabled = av[7].toString();
    boolean found = (first() != null) & userEnabled.equals("Y");
    setWhereClause(null);
    setWhereClauseParams(null);
    setMaxFetchSize(0);
    return found;
  }It gives the same exception...
JBO-27122: SQL error during statement preparation. Statement: SELECT Staff.STAFF_ID, Staff.FIRST_NAME, Staff.MIDDLE_NAME, Staff.LAST_NAME, Staff.POSITION, Staff.PASSW, Staff.USER_LEVEL, Staff.ENABLED, Staff.PHONE, Staff.EMAIL FROM STAFF Staff WHERE (Staff.STAFF_ID = :0 and Staff.PASSW = :1)
This worked in 10.0.1.2 but now it does not work in 10.0.1.3!!!
