The JSF core tag set only defines tags that correspond to basic HTML controls. There's no basic HTML control for a tabbed container.
A number of third-party extension libraries such as RichFaces and IceFaces do provide tab container controls, however.
You really need to upgrade that project, however. JSF1.0 has serious differences in its internal operation relative to later versions, even other 1.x releases. And you won't find much support for JSF 1.0 these days.
An IDE is no substitute for an Intelligent Developer.
