Found this one in my application.log:

1/30/05 5:19 PM ...: Error persisting state java.io.NotSerializableException: com.ecyrd.jspwiki.PageLock at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278) at com.evermind.server.ApplicationServer._wv(Unknown Source) at com.evermind.server.http.EvermindHttpSession._en(Unknown Source) at com.evermind._ah._tnc(Unknown Source) at com.evermind._ah._bre(Unknown Source) at com.evermind._ah._hf(Unknown Source) at com.evermind._ab._hf(Unknown Source) at com.evermind._ae._hf(Unknown Source) at com.evermind.server.ApplicationServer._hf(Unknown Source) at com.evermind._ie.run(Unknown Source) at java.lang.Thread.run(Thread.java:536)

If you are putting something into the session, it must be Serializable.


No, it does not have to be. Look at the javadocs and spec... The servlet container should not attempt to serialize non-serializable objects.

Besides, I think that it's okay that the page lock is lost in serialization. It may be that this can be a problem in some clustering systems, but I doubt anyone wants to run a clustered version of JSPWIki...
