XOM API for Processing XML with Java

[Luca Passani <passani AT eunet.no>]

Hello,

I have a servlet that uses HttpSessions to keep track of user data. I 
save Document objects in the session and when I restart tomcat I see 
this in the logs:

SEVERE: IOException while loading persisted sessions: 
java.io.WriteAbortedException: writing aborted; 
java.io.NotSerializableException: nu.xom.Document
java.io.WriteAbortedException: writing aborted; 
java.io.NotSerializableException: nu.xom.Document
       at 
java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1278)
       at java.io.ObjectInputStream.readObject(ObjectInputStream.java:324)
       at java.util.HashMap.readObject(HashMap.java:1006)

       at 
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
          :

if I remember correctly there was a lot of discussions in the past about 
how XOM objects cannot be serialized.
Now, this is not a real issue for me yet, but is there a way I can avoid 
messages like this in my logs?

thanks

Luca
