MUC and PubSub
The last release of the Tigase server included 2 our components: PubSub and MUC.
Unfortunately both components were not working with Apache Derby database. Due to a small bug. On top of that there was name change for the main class of the MUC component in the mean time I was not aware of. This causes configuration to be incorrectly generated by the installer.
We are going to release a big fix version today or at latest tomorrow for the Tigase server. In mean time for all those keen to get both components working ASAP I am giving both files to download below this article. If you want to install them, remove tigase-pubsub.jar and tigase-muc.jar from your libs/ directory and put there files downloaded from here.
For the MUC component you have to also edit init.properties file and replace MUCService with MUCComponent. Don't forget to remove the existing XML config file after before restarting the server if you edited the init.properties.
We are sorry for all the inconvenience that could caused.
