Installing Glassfish or Tomcat

[Gasuco]

Hi forum;

I need to install Glassfish open source edition v3.1 or Tomcat 7.0.11 in a VPS which has Plesk v.10, its there a sw package to do this from plesk?? if i install any of these sw from the binaries will problems occur if plesk is already installed??

Please expose your experiences with Plesk v.10 and this SW...

Thanks before hand.
