How can I add Websphere 6.1 server/runtime to Eclipse?

I'm currently using RAD 7.0.x.x but I would like to switch to Eclipse开发者_运维知识库. As far as I managed to Google, there's no way to do it (there is an example which shows it's possible by making a Genreic Server/Runtime, but that option is not available in Eclipse Galileo 3.5.2.). I could try Helios, but before downloading and installing would like to find out if this is even possible (as far as I know, it's possible to use WebSphere 6.0, but not 6.1/7).

It seems you can not, the last supported version is 6.0.
