uninstall tomcat

Hello!

I use Plesk to configure a server. Sometimes (I think)tomcat produce a lot of CPU usage.

Did I need Tomcat7 on my server ?
If not, how can I remove it?

I tried to uninstall it from the components. But I think it is still there. For example I find it afer some updates as a running process. Before I try to stop it with the command: /usr/local/psa/admin/bin/tomcatmng --stop

Thanks for help.

Regards Chris
