ClassNotFoundException when replacing with IM Gateway plugin.

Installation and Setup

Hi,

I found out today that the IM gateway plugin is discontinued and Kraken is the continuation of it. I uninstalled IM gateway and installed Kraken. And then I restarted Openfire.

However, when I login, I am getting the below mentioned exception. I downloaded smack lib from trunk, but still the org.jivesoftware.smackx.workgroup.site.* classes are nowhere to be found. I'm not sure where they come from, but all the smackx.jar files I looked into do not have these classes.

Any help in resolving this issue is heartily appreciated.

Exception:
