Hi Kim,
Thanks for the observation.
As BaseX WebSocket support is tightly coupled with Jetty, newer WAR files cannot be deployed with other web servers anymore (namely, Tomcat, Jboss, possibly others). I’ve opened an issue to get this fixed in a future release [1].
Best, Christian

I tried adding the Ecplise websocket API jar to the lib folder without success. Any ideas?
We rely on the RESTXQ for our implementations and find the dba web application very convenient for accessing the logs and managing the database.
Thank you.
