Export/Import Problem

[Kane, David]

Folks,

Folks,

I am trying to export content from one XWiki instance and import into
another instance.  After I have uploaded the XAR into the second
instance and select the archive to import, I see no change on the web
page.  If I look at the application server log, I see the following set
of error messages.  Does anyone have any suggestions about what might be
going on?

Both instances are using the same XWiki build (1.0 Beta-5.2310).  I've
already increased the max_allowed_packet to 16M in mysql, and so I think
the archive is getting attached correctly.  

Sincerely,
David Kane
