In reply to soumit. The full error message is:

ORA-30563: outer join operator (+) is not allowed here
30563. 00000 - "outer join operator (+) is not allowed here"
*Cause:    An attempt was made to reference (+) in either the select-list,
           CONNECT BY clause, START WITH clause, or ORDER BY clause.
*Action:   Do not use the operator in the select-list, CONNECT BY clause,
           START WITH clause, or ORDER BY clause.

IMHO the error message is good. I suggest to follow the instructions under "Action".

In reply to Lokesh. Yes. Simply remove the (+) in the order by clause. For example:

SELECT d.deptno, d.dname, d.loc, e.ename
  FROM dept d, emp e
 WHERE d.deptno = e.deptno (+)
 ORDER BY e.ename NULLS FIRST;
