Solved : Zimbra Chat Problems after Patching

Posted by

Another problem on Zimbra 8.8.15 is Zimbra chat. This problem occurs after patching to P6. When you login to Zimbra Webmail, you will get this error

in the mailbox.log, you will find this error

com.zimbra.common.service.ServiceException: unknown document: ZxChatRequest
	at com.zimbra.common.service.ServiceException.UNKNOWN_DOCUMENT(
	at com.zimbra.soap.SoapEngine.dispatchRequest(

As mentioned in the Zimbra forum, the problem can be resolved by following the steps below

mv /opt/zimbra/lib/ext/openchat/zal.jar /tmp
cp -rp /opt/zimbra/lib/ext/zimbradrive/zal.jar /opt/zimbra/lib/ext/openchat/zal.jar
su - zimbra
zmmailboxdctl restart

If you can’t find zal.jar, please install zimbra-drive first

yum install zimbra-drive (for CentOS)
apt install zimbra-drive (for Ubuntu)

Then, you can copy zal.jar from the zimbradrive folder as mentioned above.

Good luck 🙂
