jetspeed and struts

[Naresh Agarwal <na...@rediffmail.com>]

Hi

I'm new to the world of portals/web apps.

What is a portal framework? What is the difference between a portal framework like jetspeed and struts?

I'm looking for a tool/framework, which can help in development of a category of websites, which has basic features as follows:

1) Allows user/partner login and user/partner profiles
2) Uploading and downloading of data along with access control
3) Other features of a typical web site, like browsing with in a web site etc, fast loading of pages etc. 

What will be right choice for developing such web sites - a portal framework like jetspeed or struts web application framework?

Any leads/pointers will be greatly appreciated.

thanks,
Naresh
