Changing Tomcat sizing settings in vSphere 5.1, no GUI anymore

Hi all,

I am looking for information on changing the Tomcat settings "Initial memory pool", "Maximum memory pool" and "Thread stack" in vSphere 5.1. In vCenter 5.0 and earlier this can be done through a GUI (Start> All Programs> VMware> VMware Tomcat> Configure Tomcat.) but in vCenter 5.1 this is not available anymore. It looks like I need to edit the wrapper.conf for the various components but I can't find what to change/add in these files.

Regards,
