Hi,

I am trying to deploy xwiki-enterprise-wiki-1.3 via the import page on xwiki 1.3 using oracle as the backend database.
But encountered the following errors message, it is seem to be caused by the oracle database does not accept null value.
How can i resolve this issue?

The errors message is as follow:
