Unfortunately, Java and Tomcat are not supported on the regular Sonic web hosting platform. We do offer a "Custom Hosting" solution that allows HTTPS/SSL and some extra extensions to the usual Apache web server, but it is not a dedicated server with root access, which is usually needed for Tomcat applications.
Depending on your needs, another option is to co-locate your own server(s) at Sonic - see the following page for more info:https://sonic.com/business/colocation
