Multiple tomcat/tomee instances are running well on Windows 2008 R2 Server
for me.

- does 'not' reboot every 3 days at all
- only reboots automatically at 3am when there is a Windows update for the
Windows 2008 R2 Server
- my apps shut down with no issues and restart (via Windows Service for
each tomcat/tomee instance) with no issues
- the embedded Apache Derby database is/has never corrupted due to loss of
power or restart (for Windows update)
- never had to set or maintain TOMCAT_HOME and/or TOMCAT_BASE environment
- i only set/maintain JAVA_HOME and JRE_HOME environment variables
(whenever there is a Java version update)
- my 2 apps (and/or tomee instances) run under 500MB and 1GB of RAM,
respectively, and CPU seem to max out between 4 to 10% (on average)
- Java EE 6 full blown stack (JPA, JSF, JMS) running on main tomee instance
using under 1 GB of RAM
- Java EE 6 RESTful + JMS running on 2nd tomee instance using under 500MB
of RAM
- use tomcat7w.exe and tomee4restw.exe to start, stop, edit the Windows
Services for the tomcat/tomee instances
- Windows = piece of cake (for me)
- as Andre' mentioned, use Remote Desktop connection to connect to the
Windows 2008 R2 Server
- i remove default tomcat/tomee web app (ROOT folder, etc...) and deploy my
WAR to webapps folder
- i'm loving tomcat/tomee on Windows Server
- have 32 GB of RAM available, only using (approximately) 4GB because of my
java heap settings for both tomcat/tomee settings
