Database error on Server

Hi everyone,

 

While setting up a rm server I am getting this error while trying to set up a Realm for a web app:

 

Database error occurred while loading domain: JBAS014300: Could not find EJB with id {[52, 110, 77, 79, 33, 116, 77, 50, -84, -50, 114, 43, -115, -124, 45, 65]

 

I attach the server log.

 

I think the problem originated when I loaded a web app which I was using in another computer, and it didn't find the realm. The strange thing is that after this error, the server fails to load ANY realm, and I have no option but to restart it.

 

Thanks in advance,

    It seems the server log got lost, can you upload it?
    Did you try to Logout and Login again?

    Happy Mining,

    Did not work with login and log out. Previously I have closed all the browser, cleared all cache, then it worked. However, it is not working anymore. Why rapidminer is not solving this issue. It seems to me this issue very old. Here is the same issue 2 years earlier

    Hi. Sorry for that. Unfortunately, webapps are based on quite old technology, which poses challenges that are hard to solve. We have decided, going forward, to propose our users a different path, through our dashboarding capabilities. See here for a description. It's more modern technology and look (based on Grafana) and we encourage our users to use that, rather than webapps. Dashboards are deployed by default as part of the new RapidMiner AI Hub. They are easier to set up (no realms, for instance) and they provide similar visualization capabilities. I know it takes some time to migrate, but, especially if you're starting anything new, please use Dashboards.
