How can I return multiple values with PL/SQL Web Services

Question

Hi,
I'm new to developping Web Services. I'm doing some tests with JDeveloper and OC4J on my local machine with a Web Services based on a PL/SQL function within a package. Right now that function only returns one value. So the xml response only has one output.
I'd like to know how can I return multiple values with my PL/SQL Web Service. For example, if I want to return an employee's name and id? And that the xml contains two output : <employee>, <empid>?

ps : I have searched the forum and I couldn't find an answer to this question, if that has been discussed AND answered before, can you please post the link? Thanks

Alright, I actually found my answer. Since this was asked I think as a followup somewhere else I'll give my answer.
It is very simple, all you have to do is create an Object Type and then Return that object type. After that, JDeveloper will take care of everything and you will have an xml response with multiple values. Here
{color:#ff0000}
create or replace TYPE person AS OBJECT
( id_interv number,
first_name VARCHAR2(50),
last_name VARCHAR2(50),
date_birth date
);{color}
Then your function used in your Web Service should look something like this :
{color:#ff0000}
function info_emp (p_empno IN VARCHAR2) RETURN person AS
l_emp person := person(-1,'','','');
BEGIN
SELECT first_name
,last_name
,emp_no
INTO l_emp.first_name
,l_emp.last_name
,l_emp.emp_no
FROM emp
WHERE upper(emp_no) = upper (emp_no);
{color}
{color:#ff0000}
RETURN l_emp;
EXCEPTION WHEN NO_DATA_FOUND THEN
l_emp := person (-1,'n/a','n/a','n/a');
RETURN l_emp ;
END info_emp;{color}
{color:#ff0000}{color:#000000}After that, this is what the xml response looks like :{color}{color}
&lt;first_name xsi:type="xsd:string"&gt;John&lt;/first_name&gt;
&lt;last_name xsi:type="xsd:string"&gt;Doe&lt;/last_name&gt;
&lt;emp_no xsi:type="xsd:string"&gt;0250193&lt;/emp_no&gt;
