Error: zimlet description not found: com_zimbra_sms.xml

[crossany]

I edit the com_zimbra_sms in my window OS, I use the WinRAR to zip the
com_zimbra_sms folder to com_zimbra_sms.zip and use the WinSCP to my zimbra server .I su - zimbra and zmzimletctl deploy com_zimbra_sms.zip
the error display like this : Error: zimlet description not found: com_zimbra_sms.xml. I just zip the com_zimbra_sms.xml to the com_zimbra_sms.zip,and I use chown -R zimbra:zimbra com_zimbra_sms.
So I hope somebody cam tell us why ?
I just try to do something for zimlet

Sounds like your zip file missed the XML file, or you forgot to zip up the directory as a whole.
