Java EE perspective in Eclipse version 2.1.1 Does Eclipse 2.1.1 supports Java Enterprise Edition (Java EE) perspective? I didn't find this perspective when I downloaded eclipse 2.1.1 from eclipse archives website. I've to use this very old version of eclipse because I'm working on a legacy application and it uses some very old eclipse plugins that are only supported in older versions released before the year 2003. Any support regarding this would be highly appreciated.

No. WTP's original code contribution to Eclipse took place in 2004. Prior to that, its contents lived in other commercial products and Open Source projects, and the perspective definition itself and a lot of the associated Java EE support was in an IBM commercial product.

I can't say for sure because this is so old, but I would think it very unlikely.
Eclipse 2 had a different way of describing plugin dependencies which newer plugins don't use, so anything that is not built for Eclipse 2  won't work.
