Answer 1

This indicates a problem with the deployment of the publish transaction (so it goes wrong on the content delivery side of the solution not on the content management side).

Troubleshooting such issues can be a difficult process especially "over the wire" like you are asking us to do here...

I will limit my answer to general guidelines on how to troubleshoot deployer issues:

1. Does this happen for all pages that you unpublish? Across all publications? Or only for some page? What makes this page "special" compared to others (if applicable)?
2. Does this happen always or is it a random occurrence?
3. Are there any non-standard extensions to the storage mechanism or the deployer? Does disabling these solve the problem?
4. How do your storage and deployer configuration compare to the "default" configuration supplied as samples as part of the Tridion installation sources?
5. Have you enabled debug logging of the deployer application? This usually reveals additional information about what it is doing when the error occurs...
6. Does the "lib" folder of your deployer application have all of the libs that Tridion provides in the Tridion installation sources for this role?

Usually problems of this nature revolve around either - incorrect configuration settings in the storage configuration - missing/incorrect jar files in the lib folder
