It depends on your service, if you have shared JSP or Java web hosting.
When you ftp or SSH in, you are dropped
/home/username/
Upload your tomcat webapp here:
AppBase: /home/username/yourdomain.com/tomcat/webapps/
You may utilize the existing ROOT webapp or create your one via .war package. It is best practice to create your own web app instead of using ROOT.
Or you can use Tomcat Control within your Siteworx control panel to upload your war file.
