Subject [jira] Commented: (GERONIMO-4846) form based security for the web application does not work with Jetty WADI clustering.
Date Fri, 30 Oct 2009 15:49:59 GMT


Trygve Hardersen commented on GERONIMO-4846:

I've not tested WADI with Jetty7 for a while now but last time I checked it behaved very differently
from Jetty6. With Jetty7 I can't used form-based security, with Jetty6 I can. 

You're right this is not part of the spec but if you can't use WADI with form-based security
it must be documented as a change between 2.1 and 2.2 I think. I can do another test if you

The first problem is that$SessionAuthentication
and are not serializable,
so they can not be sent across the network. I made these classes serializable, and then login
works as long as there is only one member in the cluster (well, not really a cluster...).
When there are multiple members in the cluster, login fails because there is no valid constructor
I tried to add a default constructor, but it's an inner class, and it seems to me like theAuthenticator
and UserIdentity properties are required for it to work so I did not try to extract the class.
> As I said login works as long as there's only one member in the cluster, but logout does
not. Calling javax.servlet.http.HttpSession#invalidate() throws an exception, because the
curent session can not be found:
> java.lang.AssertionError: Session [org.apache.geronimo.clustering.wadi.WADISessionAdaptor@7f488ddb]
is undefined
> org.codehaus.wadi.replication.manager.ReplicationKeyNotFoundException: Key [ccge2q2w9dz2]
does not exist
> I am attaching the patch for the WADIJettyClusteringBuilder (WADIJettyClusteringBuilder.patch)
and a sample project JGS (jgs.tar.gz) that demonstrates the security problems I'm experiencing.
The web-formlogin-clustering-plugin of the JGS project uses form based security and WADI clustering.
The /customer page is protected, and to access it one must login with any username and password,
as long as they are the same. Use test/test for instance. To test session invalidation, manually
enter the URL /logout.
> It would be very helpful if someone can comment on the usability of WADI clustering in
combination with Jetty7. To me it seems like it has not been tested much, and I think going
back to Jetty6 again is the best option for us, unless the issues described above can be easily
