Can I reference environment variables in eclipse while defining a (tomcat) server?

I 开发者_运维问答am using eclipse Galileo. The "New Server Runtime Environment" dialog box contains three fields:

• Name
• Tomcat installation directory
• JRE

I would like to set the tomcat installation directory relative to an environment variable I have set in my OS (win xp).

Can this be possibly done?

I don't think so. I suggest to open a feature request against the Web Tools Project WTP. It should be a simple fix.
