Hi all,
We want to implement tomcat clustering, but we cannot because the application
is commercial, and it does not support serializable objects. In short, it does
not work with tomcat's standard clustering technology. Is there any known
reliable way to share session state, cookies, etc., between tomcat instances,
without using tomcat's native clustering facilities, and without having access
to the application code? I know it's probably a dumb question, but I must ask.
What are you trying to achieve?
Sharing the load between multiple servers?
Fail over (with data loss) if one server fails?
Fail over without data loss if one server fails?
The first two can be done. The third would require some tool that could
reliably serialize any Java object regardless of whether it was
serializable. I haven't come across such a tool but that doesn't mean
one doesn't exist.
