The error is inside the webapp. The error message is following:
20040714 01:43:46 ERROR - Exception Message
[java.lang.NoClassDefFoundError
at com.xxx.Manager.getUser(Manager.java:525)
Line 525 in Manager.java has the following code:
User user = new User();
The class User is a java bean that implements Serializable. Later in a
servlet the user object is put under session as an attribute.
If the session is still active and TC is restarted, I get the above
exception. There are no problems if the session is cleaned in the
webapp.
Also, this started hapenning only after the User object was made to
implement serializable. There are no problems if the User object
doesn't
implement Serializable.
Does TC behave different for serialized objects?
Thanks

Hi,
TC persists the session, yes, but that doesn't explain a
ClassNotFoundException. Is the CNFE in your own code? If so post the
relevant chunk.
