Re: [jetty-users] Jetty server 7.1.3: NonSerializableException thrown when running JAAS and Session Clustering with DB together
Jesse,
      I am resetting the config right now since I have added the whole jetty server folder as a part of my web project. 
      I will let you know when I get the result.

      Thanks,

      Mike J.

Thanks a lot.
One quick question: is this file working for my Windows Vista System? I can unzip it using 7-zip but not sure if it is for windows also.
Another question: Since for jetty server 7 or above, there is no a jetty server plugin for Eclipse ( there is one for jetty server 6.x), I must bound the jetty server myself with my web project by using Eclipse's Launching config if I want to run debugging mode, I was wondering if there is one such plugin soon?

Best regards,

Mike J.

I am pushing up a snapshot with that fix you can try out if you like..its uploaded as I write this so give it a few minutes to finish

I suspect I'll be re-rolling the 7.2.0 release today so this fix will be included in that release if it works for you

let me know if that fix takes care of the problem I did a quick poke around for any others like that but didn't see anything jump out

Hi, All
     I have used the jetty server 7.1.3 as the app server for a while. First the JAAS (Java Authentication and Authorization service) is used and it worked with no error. 
     Secondly, we tried to use the Session Clustering with Database, a feature offered by the jetty server also. It's for the case in which there are multiple server instances running in a load balancing environment. The DB is used as a persistent storage for the session's attributes so the attributes can be shared by the server instances.

     However, when the JAAS and Session Clustering with DB are in effect at the same time, a NonSerializableException  was thrown as follows,

   Debugging into the code, it was found that the problem was caused in the following steps:


   1). In the process of the JAAS, the code sets a class: SessionAuthentication as a session attribute. SessionAuthentication is implemented as a serializable object but its member, DefaultUserIdentity is not. So the SessionAuthentication is not a serializable object at all;

   2). In Session Clustering with DB process, the JDBCSessionManager tried to save all the sessions' attributes-all of them must be serializable-to the database. However, one of the attribute, SessionAuthentication, is not a serialiable object, so the above exception is thrown and the process is interrupted.


   Kindly hope you can help me for this.


   Thanks,


   M. J.
