OFMeet 0.3.8 has been compiled with Java 8, while your Openfire instance is running on Java 7. I am busy putting out a new version of OFMeet that is compiled with Java 7. That will resolve this issue.

As a work around, you could upgrade the version of Java that you have installed (which generically is a good thing^© anyway).

Rafael_Ugalde_Beriai · February 4, 2016, 1:40pm

Ok, I will try it and comment the result.

guus · February 4, 2016, 4:18pm

OFMeet version 0.3.9 is now available for download at Ignite Realtime: Openfire Plugins

This version will fix the problem.

Rafael_Ugalde_Beriai · February 5, 2016, 7:19am

Great, It’s working with 0.3.9 and java 7.

Thanks.
