The request.getAttribute("") problem in SSO interface

[Migrated From Jforum.net]

I write a filter fitering all the *.page, and write code in it like this

request.setAttribute("aa","bb")

.then I write another class named "SSODemo" implements SSO interface.
In SSODemo's "authenticateUser(RequestContext request)" method I want to get the attribute "aa" by this code

request.getAttribute("aa")

, however, the return value is null, is there some thing i missed?


Thanks.

one thing could be that you wrote the setAttribute after you already used the filter chaining ... so the request is at the server at a time before you modified it
