Hi,
i have a similar question.
I have a spring bean exposed as web service: it is a singleton and gets the
context injected to work with the http session:
...
@Resource
private WebServiceContext context;
public String login(String username) {
String challenge = auth.login(username);
if (challenge != null) {
((HttpServletRequest)
context.getMessageContext().get(HTTP_REQUEST)).getSession().setAttribute(USERNAME,
username);
...
Is it safe or i should turn the bean into a prototype ?
Thanks,
Nicola
