Werner,
Yes, I'm obtaining a Database connection to a HttpSession. Each HttpSession gets it's own Database connection. I'm getting this exception, but the data is stored in the database. I configured Tomcat to use Cookies for my website and I don't get the exception anymore.
What do you mean, with change the usage of Castor? How can I use the connection with Tomcat? Do you have an example?
regards,
markus

Markus,
you get this exception because Database(Impl) simply isn't serializable, and imho shouldn't be either.
Can you just briefly explain why you are getting this exception ? Or even better, what's the problem you are trying to solve. It looks like you are binding a
Database instance (as obtained via JDO.getDatabase() to a HttpSession, correct ? If that's the case, I'd consider to change your usage of Castor, as
obtaining Database instances from JDO is not expensive at all (especially when using a connection pool with Tomcat).
Regards
Werner

NotSerializableException
HI,
I get an NotSerializable using castor within an EJB in Tomcat 4.1.27. Any Ideas why? What is the workaround?
thanks,
markus
